Use this skill to turn moomoo OpenD option data into an actionable gamma map and a plain-language trading note.

This public-safe skill is self-contained. Do not commit personal information, API keys, account data, private RAG files, or any Stocks folder contents to GitHub. It may use a user-specified private RAG folder during a session, but it must not store private source paths, personal positions, original strategy names, private person names/handles, proprietary labels, or private document titles. Generic market concepts such as gamma, GEX, dealer hedging, FVG, KDJ, MACD, RSI, VWAP, and Vegas may be retained.

Experience

Cross-skill calls are operational. When this workflow says to use another market skill, actually load that skill's SKILL.md and required references when available in this package or environment. Do not merely mention the other skill by name in the answer.

Required coordination: for US option/gamma analysis, use this skill as the positioning and option-structure entry point, and add supporting skills based on the analysis workflow, not only on the user's wording. If the analysis is about SPX, SPXW, SPY, QQQ, Nasdaq, Dow, Russell, VIX, Nikkei proxy gamma, or any broad index/ETF gamma map, load macro-news-check because index gamma cannot be read well without current macro and broad-market tape. If the analysis discusses news acceptance, theme crowding, risk-on/risk-off tone, forum/social sentiment, or leader/follower context, load stock-sentiment-analysis. If the final view depends on support/resistance, intraday timing, trend confirmation, failed breakout, or price-action validation, load stock-technical-analysis. Gamma is the positioning map; macro, sentiment, and chart structure decide whether the map is being accepted or rejected.

When official moomoo anomaly skills are installed, use them as an auxiliary scan layer, not as a replacement for the self-calculated gamma map. For user requests involving 异动, 大单, IV, PCR, 聪明钱, unusual options activity, option sentiment, or volatility anomaly, call moomoo-derivatives-anomaly alongside this skill by default. For U.S. stocks, do not request Hong Kong-only warrant / CBBC dimensions; use only U.S.-applicable option dimensions such as option_unusual, option_volatility, option_volume_price, option_sentiment, and option_comprehensive. A full scan can fail if it includes Hong Kong-only dimensions, so narrow the dimensions explicitly when needed.

If the analysis uses 1-minute K-line confirmation from moomoo OpenD, coordinate with stock-technical-analysis: let this skill fetch or compute the option/gamma map, then use the technical skill's framework to judge whether price action accepts, rejects, or only probes a wall, pit, or flip. If the user asks why a U.S. stock moved, whether earnings/guidance/news were accepted, or what explains a price move, route the evidence-gathering entry point to us-stock-move-reason first, then use this skill only for the option-positioning layer.

For ordinary U.S. stock move analysis, ChartExchange-style off-exchange/dark-pool data can be a secondary confirmation layer when price action or option positioning leaves an open question. Use it after confirmed news, macro/sector tape, price/volume, and option/gamma evidence. It is most useful for hidden-liquidity context around unusual volume, unexplained moves, failed news reactions, squeeze candidates, or repeated support/resistance at specific prices.

Mandatory Execution Gate

Before running scripts or writing the final answer, classify the request and load required sibling skills:

• Broad index / ETF gamma (SPX, SPXW, SPY, QQQ, Nasdaq, Dow, Russell, VIX, Nikkei): load macro-news-check first or in parallel, then explicitly merge the macro tape with the gamma map. Do not answer index gamma from gamma data alone.
• 宏观 / 快讯 / rates / FX / commodities / geopolitics / Fed / yields: load macro-news-check. Do not substitute ad hoc web search for this layer.
• 技术面 / intraday execution / "now" / support-resistance / "can it get through" / price action: load stock-technical-analysis unless the user asks for a pure option-positioning dump. Use price action to decide whether a wall/pit is accepted, rejected, or only a battlefield.
• 官方 moomoo 期权异动 / 大单 / IV / PCR / 聪明钱: when moomoo-derivatives-anomaly is available, run it as a parallel anomaly scan using U.S.-applicable option dimensions only; do not include Hong Kong warrant / CBBC dimensions for U.S. stocks.
• 情绪面 / news acceptance / crowding / risk-on or risk-off psychology / expectation gap: load stock-sentiment-analysis when sentiment or expectation gap changes the interpretation.
• 新闻接受度 / 财报 / 指引 / 股价为何涨跌: use us-stock-move-reason as the upstream catalyst workflow, then merge its evidence with this skill's gamma map.
• Dark pool / off-exchange / borrow / FTD / short-volume checks for U.S. stocks: use ChartExchange or the original FINRA/borrow-data source only as a secondary positioning layer. Do not use dark-pool prints or off-exchange share alone as a bullish/bearish signal.
• If a required sibling skill is unavailable, say so and provide a limited gamma-only read. If it is available but not needed, state the reason briefly.

Final answers for index gamma should include a compact 融合口径 line naming the layers used, for example: 自算 SPXW gamma + macro-news-check tape + stock-technical-analysis price action + stock-sentiment-analysis emotion/expectation gap. This makes skipped or missing skill fusion visible.

DTM SPX Reference

For SPX/SPXW context, first reference the canonical https://daytrading.monster/api/gamma/ interface documented in https://daytrading.monster/api-docs/gamma. Parse its text/plain body as JSON and check its session/update time. It provides current SPX structure, expiry summaries, selected strike levels, Camarilla, and 0DTE five-minute samples. Use price_trajectory.points (timestamp, index_value) to read all available SPX source prices in the returned session; these are price-only points, not interpolated or guaranteed tick-complete. It is a fixed SPX/SPXW reference, not a full strike grid or an arbitrary-ticker endpoint. Keep the existing moomoo collection and computation workflow for full-chain calculations, requested scenario/heatmap detail, and other stocks or ETFs; do not present a DTM snapshot as a local calculation. Reuse an applicable upstream snapshot instead of requesting it twice.

Default Output

Route the request before choosing a script:

• Ordinary US stocks/ETFs: use the installed standalone gamma_report.py collector, if available, or a complete chain from another authorized tool, then interpret the output with the Single-Stock Directional Framework below before giving a bullish/bearish view.
• SPX / SPXW / SP500 / 标普500 / S&P 500 index gamma: do not use gamma_report.py as the final workflow. Use a current SPX/SPXW chain (the external spx_intraday_latest.py collector is one optional route) and spx-intraday: query US..SPX, keep SPX/SPXW strikes directly, infer the spot anchor from SPXW 0DTE put-call parity when the SPX index snapshot is unavailable, and treat SPY only as a sanity check or fallback.

After the U.S. options session closes, never retain an expired same-day SPXW chain in a forward chart or memo. Start from the next listed unexpired expiry; the script uses that front expiry in the existing 0DTE calculation bucket so its Flip, walls, range, and comparison logic remain front-expiry based. Label it as a next-expiry proxy after close, not as live 0DTE.

• Nikkei / 日经 / 日経 / NKY / Nikkei 225 index gamma: do not present raw EWJ ETF strikes as index levels, and do not use a current Nikkei anchor against a stale EWJ close. Use EWJ only as a proxy option book, then convert with a time-aligned bridge: EWJ quote-time value -> NKDmain/Nikkei futures at that same time -> current NIYmain/Nikkei CFD or the user's current index anchor. The external proxy_index_gamma.py collector is optional; reproduce the bridge only from actual time-aligned inputs. The report must state every anchor, ratio, timestamp, and limitation.

Default to a concise chat/terminal text summary. Do not create files as part of this skill unless the user explicitly requests raw JSON export.

For SPX answers, default to the detailed index-gamma format. The answer should be detailed enough to explain claims such as “still negative gamma, 7450 starts neutralizing, 7500 becomes stronger positive gamma” from data. Include:

• SPX anchor and anchor method.
• 0DTE, Next2, Fri2w, and All-window net GEX, net VEX, flip, top walls, and top pits.
• A key-strike cross-section showing 0DTE / Next2 / Fri2w / All GEX and All VEX at nearby decision levels, especially current rounded strikes, major walls, major pits, and user-mentioned levels.
• A distinction between aggregate regime and local strike regime: All still negative can coexist with 7450/7500 locally positive.
• A conclusion that says whether each level is downside acceleration, neutralization/repair threshold, or stronger positive-gamma pinning wall.

多日期、同日比较与热力图请求须实际计算逐到期日结构，并读取对应参考；比较只使用实际取得的旧快照。

Use only real listed expiries from the JSON. Each chart column, Flip, Call Wall, and Put Wall must use only contracts expiring on that column's date. The solid foreground/black line is each expiry's gamma flip, not a price forecast; the dashed line is the current SPX anchor. The left All GEX profile must mirror all selected-expiry Call-side GEX right of zero and absolute Put-side GEX left of zero on one shared scale; overlay the raw Net GEX as a thin line. The right heatmap remains Net GEX only. Call Wall is the strike with the largest call-side GEX for that expiry; Put Wall is the strike with the most negative put-side GEX. Do not substitute maximum all-strike OI, which can select far-OTM legacy positions with little current gamma. The heatmap may smooth the visual layer along strikes, but must preserve the raw GEX calculations, Flip, and Call/Put Wall values. Read gamma-heatmap-visualization before changing the range, smoothing, or chart semantics.

When no axis range is explicitly requested, render SPX from floor(spot / 100) * 100 - 300 through ceil(spot / 100) * 100 + 300. For example, an anchor of 7480 renders 7100–7800. Explicit --min-strike and --max-strike remain available for a user-requested audit range.

For Codex inline display, generate the fragment inside the thread-scoped visualization directory and emit ::codex-inline-vis{file="basename.html"} using only the file name. The fragment must use its generated unique root ID with document.getElementById, never document.currentScript. Show desktop CW and PW values on separate rows so adjacent expiry columns remain readable. Do not create or publish a website unless the user explicitly asks for one.

完整计算流程：

• reads stock snapshot, option expirations, option chain, option snapshots, and daily K lines from moomoo OpenD;
• throttles get_option_chain calls and retries once after OpenD frequency-limit errors, because moomoo can reject more than about 10 option-chain requests in 30 seconds;
• chooses the pricing anchor by U.S. session: regular last_price, after-hours after_price, overnight overnight_price, pre-market pre_price, then bid/ask midpoint or regular last as fallback; label it as a pricing anchor, not guaranteed live tradable price;
• gathers option OI, IV, delta, gamma, theta, vega, bid/ask, volume;
• calculates Black-Scholes vanna from live/anchor spot, strike, IV, and DTE because moomoo snapshots may not provide option_vanna;
• selects option expiries by default as: all weeklies within the next 2 calendar weeks when available, plus monthly expiries for the current month and next 2 months; for high-frequency option names also include the next 2 trading-day/daily expiries when listed;
• calculates signed GEX with the common assumption Call = +, Put = -;
• calculates signed VEX with the same directional convention, expressed as spot-equivalent delta-dollar change per 1 vol point IV move;
• calculates option delta exposure (DEX) and approximate charm exposure by strike, plus call/put OI shelves and front-expiry IV smile/skew;
• prints a complete OpenD gamma data group by default: pricing anchor, VT/flip, gamma wall, call wall, put wall, distance to VT/CW/PW, net GEX, net VEX, net DEX, charm/day, gamma pits, vanna zones, DEX zones, charm zones, OI shelves, IV smile/skew, and a conclusion that explicitly combines these dimensions;
• recomputes gamma across a spot-price grid to estimate gamma wall, gamma trough, and gamma flip;
• when JSON output is requested, includes per-strike gex_by_strike and vex_by_strike for each bucket so later runs can detect same-strike support/risk migration instead of only comparing top walls and pits;
• includes a per_expiry section in JSON for each selected expiration date, so future-days gamma reads can say which exact date is weaker or stronger instead of only using Next2 / Fri2w aggregate buckets;
• includes per-expiry call_wall and put_wall from side-specific GEX within that expiry; preserve null when no valid level exists;
• with --by-expiry-report, prints a per-date forward gamma memo that names each selected expiry date, net GEX, flip, main downside risk zone, upper pressure/pinning zone, and a baseline/bearish/repair scenario; use this mode for single stocks too when the user shares or asks about multi-expiry vol-trigger/gamma-wall tables;
• with --compare-json, compares the new snapshot with a prior JSON snapshot and highlights material strike-level changes, including positive-to-negative GEX flips where a prior support/wall has disappeared and become a pit or acceleration risk;
• prints a readable text memo by default; JSON export flags should be used only when the user explicitly asks for raw data.

For SPX 0DTE or quick trading questions, chat/terminal text is the default. Still compute or fetch the chain first when possible.

Read extra references only when the request needs them:

• For .SPX, SPXW, SPY, ES, SpotGamma/TRACE heatmap, or intraday index judgment, read spx-intraday.
• For a continuous multi-expiry SPX gamma heatmap, visual smoothing, or same-session chart comparison, read gamma-heatmap-visualization.
• For short-dated option value tables, account-recovery option targets, or “what is this call/put worth if price reaches X by time Y”, read option-scenario-tables.
• For U.S. single-stock dark-pool/off-exchange, borrow-fee, short-volume, FTD, or ChartExchange confirmation, use the Dark Pool / Short Data Layer section below.

Single-Stock Directional Framework

For ordinary U.S. stocks and ETFs, the default job is not only to calculate gamma; it is to convert option structure into a directional trading read. Use this framework whenever the user asks 看多还是看空, bullish or bearish, 能不能追, 支撑压力, 未来几天 gamma, or shares third-party gamma screenshots/tables.

Start with the shortest useful answer:

1. State a direct bias: 偏多, 偏空, 中性偏多修复, 中性偏空防守, or 高波动战场.
2. Name the current spot and the one or two levels that decide the bias.
3. Say what changes the conclusion: reclaim/hold above an upper trigger, or lose a lower support/put wall.

Directional labels are incomplete without levels. Whenever using labels such as 中性偏多修复, 偏多钉扎, 中性钉扎, 偏空/高波动, or 高波动战场, immediately attach the price zone that makes the label actionable:

• Current spot / pricing anchor: state the current spot or pricing anchor before the directional label or in the same table row. A level is only actionable relative to spot; say whether spot is below, inside, or above the key zone. Example: 现价 198.18，偏多钉扎，钉扎区 200 附近.
• Pinning zone: name the exact strike or tight range being pinned, usually the nearest dominant GW, CW, PW, or confirmed OI shelf near spot. Example: 偏多钉扎，钉扎区 200 附近.
• Repair / confirmation level: for repair labels, name the level that must be reclaimed or held, usually VT/flip first, then the nearest GW/CW. Example: 中性偏多修复，站稳 295，突破 297.5 才打开上沿.
• Invalidation / downside risk: name the put wall, flip, or gamma pit whose loss invalidates the bullish/neutral read. Example: 跌破 290/284.6 则修复失败.
• Battlefield range: for mixed or high-volatility labels, give the actual range between the nearest support and pressure levels. Example: 高波动战场，260-350 是主战场，跌破 205 扩大下行.

Do not output a direction-only label when current spot, VT, GW, CW, PW, gamma pits, or OI shelves are available. If current spot or precise levels are unavailable, say 现价/关键点位不足 and lower confidence instead of presenting a clean directional label.

Always build the read from these layers, in this order:

1. Spot vs vol trigger: treat the nearest major vol trigger or gamma flip as the regime divider. Spot below the trigger means higher-volatility/negative-gamma risk unless price reclaims it. Spot above the trigger allows repair but still needs confirmation above the nearest wall.
2. Spot vs gamma wall: gamma wall above spot is pressure, pinning, or a repair target; gamma wall below spot is support or a recapture zone. If spot is trapped between a put wall and a call wall, call it a battlefield instead of forcing a strong directional view.
3. Call wall / put wall distance: nearest call wall is the first upside pressure or pinning reference; nearest put wall is the first downside support. A wide gap between walls allows trend movement; a tight gap implies chop/pinning.
4. Per-expiry net GEX: identify which expiry actually dominates. Near-dated negative GEX can overpower longer-dated support and create squeeze/crash-style movement. Mixed positive and negative expiries mean conditional bias, not a clean all-in view.
5. Open interest shelves: use absolute OI to confirm where real option interest clusters. Treat large OI shelves above as pressure/pinning references and below as support/risk zones; do not assume OI alone reveals buyer direction.
6. IV smile and skew: high IV and steep downside skew strengthen the warning that the structure is defensive or volatility-seeking. A large vol smile with both call and put blocks often means long-vol/straddle/strangle positioning, not simple bullishness.
7. Unusual option flow: classify prints as directional only when they are clean single-leg buys/sells and the bid/ask side is visible. Treat multi-leg, condor, butterfly, straddle, strangle, or paired call/put prints as volatility/range trades unless price action proves direction.
8. Delta hedging exposure: use net delta-hedging pressure as a secondary force map. It can confirm where dealer hedging may add buying/selling, but it should not override spot vs trigger/wall structure.

Use the following directional rules:

• Bullish repair: spot is above the nearest vol trigger or reclaims it, holds above the nearest put wall/support, and has room to the next call wall. Wording: 站上 X 才算修复，第一目标 Y，突破 Y 才看 Z.
• Bearish pressure: spot is below the nearest vol trigger/gamma flip, near-dated net GEX is negative, and losing the nearest put wall opens a lower put wall or gamma trough. Wording: 跌破 X 转空，下一层看 Y/Z.
• Neutral battlefield: spot sits between a nearby put wall and call wall, or per-expiry GEX is mixed. Wording: X-Y 是战场，不追单边；等站上 Y 或跌破 X.
• High-volatility warning: spot is below trigger with negative GEX, IV is high, and option flow shows large puts or long-vol structures. Wording: 不是单纯看空，是波动放大；方向等关键位确认.
• False bullish signal: do not call it bullish only because call wall is far above spot. A far call wall is potential upside/pinning only after spot reclaims trigger and nearby resistance.
• False bearish signal: do not call it bearish only because put OI is large. Put wall below spot can be support until it breaks; after it breaks, it becomes acceleration risk.

For third-party trigger/wall table interpretation, map fields this way:

For a complete OpenD-generated gamma memo, include these dimensions when the data is available:

When the user asks only "看多还是空", answer in this compact structure:

1. 结论: one line, e.g. 中性偏多修复，但不是确认多头.
2. 关键位: 上方确认 X/Y, 下方失守 A/B.
3. 为什么: three bullets maximum, using vol trigger, walls, and per-expiry GEX/flow.
4. 交易口径: one sentence such as 不追，等站上 X；跌破 A 则按偏空处理.

Text Level Map And Session Memory

For SPX/SPXW and other index-style intraday gamma answers, expose the level work as text: short bullets, compact Markdown tables, and a direct bias line. Do not rely on visual-only interpretation.

For forward-looking requests such as 未来几天 gamma, 未来几日 gamma, 后面几天 gamma, 哪天强哪天弱, or a screenshot showing several expiry dates, do not answer only with 0DTE / Next2 / Fri2w tables. Compute per_expiry from the available complete chain. If the corresponding external collector is installed, SPX/SPXW can use spx_intraday_latest.py --by-expiry-report and ordinary stocks can use gamma_report.py --by-expiry-report; these collectors are not bundled. Then answer in this structure:

1. Start with one sentence: 从“未来几天 gamma”角度看：... and say whether the next 1-3 days are repaired, weak, high-volatility, or pressure-first. Name the key repair zone.
2. Add 按具体到期日看： and one short paragraph per expiry date, e.g. 2026-06-09 周二，当天到期, 2026-06-10 周三, 2026-06-11 周四, 2026-06-12 周五. For each date, state: weak/strong label, net GEX direction and rough size, flip, main downside put-gamma risk zones, upper call-gamma pressure/pinning zones, and what price must reclaim to improve.
3. Add 我的推演： with exactly three scenario bullets: 基准情形, 偏空情形, and 修复情形. These scenarios should use dates and levels, not generic statements.
4. End with a plain conclusion such as: 所以按日期结论是：周二最弱，周三/周四仍偏压制，周五有修复窗口但门槛在 7450。

For this mode, avoid dumping every strike or table row. The user wants the trading meaning: which date is structurally weak, where risk migrates, where repair starts, and what would invalidate the weak/strong read.

Key calculated levels:

• Prior-session pivot map: use the prior regular-session high/low/close when available. PP = (H + L + C) / 3, BC = (H + L) / 2, TC = 2 * PP - BC, R1 = 2 * PP - L, S1 = 2 * PP - H, R2 = PP + (H - L), S2 = PP - (H - L). For Camarilla, use unit = 1.1 * (H - L) / 12, then H3 = C + 3 * unit, H4/H5/L4/L5 follow the explicitly selected vendor/formula convention; do not mix variants.
• CPR interpretation: narrow abs(TC-BC) means a larger directional expansion is easier; wide CPR means more chop/mean reversion. Spot above max(TC,BC) is constructive, between the two boundaries is a balance zone, and below min(TC,BC) is weaker unless reclaimed.
• Gamma map: wall above spot is pressure or pinning; wall below spot is support or a recapture zone; negative pit below spot is acceleration risk; flip or vol trigger is the regime divider. Say whether the current spot is above/below flip/trigger and whether GEX is strengthening or weakening.
• Vanna map: combine top positive/negative VEX zones with IV direction, spot versus flip, and price action. Do not describe VEX alone as bullish or bearish. When the user runs this skill multiple times during the same trading day in the same conversation, use earlier same-day results as optional but important context. Compare the new result with the earlier answer when migration could change the judgment, when the user asks "now/again", or when spot is near a wall, pit, flip, or trigger: spot, net GEX, net VEX, flip, nearest wall, nearest pit, and CPR relationship. State what migrated and what strengthened/weakened. If a prior JSON snapshot exists or the user provides one, compare the same fields and contract coverage. An installed external collector may support spx_intraday_latest.py --compare-json ... and --watch-strikes; otherwise compare through the available computation tool. Include any user-specified level such as 7400支撑还在吗. Always check whether the same strike's GEX sign or magnitude changed materially across 0DTE, Next2, Fri2w, and All buckets, but do not mechanically dump same-strike change rows in the final answer. Translate the comparison into what it means and what it may foreshadow: support quality deteriorating or recovering, risk center migrating lower/higher, upper pinning weakening, reflexive selling/buying risk rising, or chop/pinning returning. Treat positive-to-negative GEX migration at an active battlefield strike as 支撑跑路/降级为加速风险, not merely as a lower wall ranking. Treat negative-to-positive migration as 支撑恢复/加速风险缓和, but still require price action to confirm. If no earlier same-day result exists in the conversation or user-provided notes, do not imply there is an internal time series.

Dark Pool / Short Data Layer

Use this layer only for U.S.-listed stocks and ETFs. Do not apply it to A-shares, Japanese stocks, or non-U.S. local listings.

When using ChartExchange, build the URL from both listing venue and ticker. The path shape is:

https://chartexchange.com/symbol/{exchange-lowercase}-{ticker-lowercase}/exchange-volume/dark-pool-levels/

Examples: nyse-anet, nasdaq-nvda, nyse-spy. SPY is a common exception where ChartExchange uses nyse-spy, so search the ticker on ChartExchange or a quote source first when the venue is uncertain, then use the matching venue in the URL. Do not reuse an ANET URL for other tickers without changing both ticker and venue.

Interpretation rules:

• Off Exchange & Dark Pool %: compare today's share with the ticker's own average. A high off-exchange share is common in U.S. equities and is not bullish or bearish by itself.
• Dark Pool Levels: treat high-volume price levels as hidden-liquidity reference zones. They become support/resistance only if later price action confirms acceptance, rejection, or repeated defense.
• Dark Pool Prints: large prints near VWAP, gaps, prior highs/lows, or post-news levels are notable, but the data does not reveal whether the initiating side was accumulation, distribution, internalization, or a cross.
• Short Volume: daily short-sale volume is not short interest and often includes market-maker activity. Use it for flow pressure only, not for outstanding short exposure.
• Short Interest, Borrow Fee, Shares Available, and FTD: use these for squeeze risk. Stronger squeeze evidence is rising borrow fee, shrinking availability, elevated short interest/FTD, and price refusing to break down after heavy short/dark flow.
• Always combine this layer with news acceptance, live price/VWAP, volume, and option/gamma structure. If the conclusion depends on a dark-pool level becoming support/resistance, load stock-technical-analysis and require price confirmation.

Required Interpretation Style

Write like a pre-market trading memo:

1. 结论: direct bias first: bullish, bearish, neutral battlefield, or high-volatility watch. Do not bury the answer behind tables.
2. 关键位: current spot, nearest vol trigger/flip, first call wall, first put wall, and the level that changes the view.
3. 我会怎么做: concrete scenario handling, e.g. “do not chase until it holds X”, “treat X-Y as chop”, “above Z opens next target”.
4. 什么情况说明我错了: exact invalidation levels.
5. 怎么和技术确认配合: use gamma as the map, then confirm entries/exits with stock-technical-analysis concepts such as KDJ, MACD, MA144/Vegas, FVG, volume, and price action.

Avoid only dumping tables. The user wants judgment, assumptions, and a clear action framework.

Multi-Stock Gamma Output Contract

When answering a batch request with multiple stocks, ETFs, or mixed tickers, every row must include both:

• Current spot / pricing anchor: the latest usable spot or anchor price used for option calculations, with the source/session caveat when relevant. Do not make the reader infer where price is relative to the levels.
• Gamma sign / regime: positive, negative, or mixed, with Net GEX when available. This is the dealer-hedging/volatility map.
• Directional state / bias: 偏多修复, 中性钉扎, 中性偏空防守, 高波动战场, or another explicit long/short/neutral state derived from spot vs flip/walls/pits. This is the trading interpretation.
• Actionable key levels / zone: the exact pinning area, battlefield range, repair trigger, upside pressure, and/or downside invalidation that justifies the directional state. At minimum, include the nearest VT/flip, GW/CW pressure or pinning reference, and PW/pit support or risk when those fields are available.

Do not let one replace the other. A stock can be 净 GEX 为正 but still 中性偏空/高波动 if spot is below the volatility trigger or trapped under a nearby wall; a stock can be locally positive gamma but still a poor long setup if it has not reclaimed the trigger. In tables, prefer columns like:

Ticker | Spot anchor | Gamma sign / Net GEX | Directional state | Key zone / pinning area | Flip/VT | Upside wall | Downside risk | What changes the view

For batch summaries, group names after the table by directional state, but keep the per-row spot, gamma sign, and key levels visible. If space is limited, abbreviate commentary first; do not omit the spot/anchor, gamma regime, direction, or actionable price zone.

For multi-expiry batch reports, each expiry row must show the date-specific levels, not only the all-expiry levels. Use the expiry's own VT, GW, CW, PW, net GEX, and pits when available. If describing 本周 and 下周, give both periods' gamma sign, directional state, and actionable zone separately because the same ticker can pin this week and become high-volatility next week.

When news or broad risk sentiment is driving the underlying or index, call macro-news-check only when current macro tape can plausibly change the gamma read, such as CPI/PCE/FOMC/central-bank events, Treasury yield shocks, USD moves, oil/gold/geopolitical headlines, index futures breaks, or sudden risk-on/risk-off tape. Use stock-sentiment-analysis if deeper emotion-cycle framing is needed, and add an expectation-gap check before relying on the gamma map: prior market expectation -> actual news -> above expectation / in line or merely landed / below expectation. Apply this to numeric headlines such as orders, CPI/FOMC data, earnings, guidance, and ETF flows, and to qualitative headlines such as regulatory wording, geopolitical tone, management confidence, timing, certainty, and whether the news solves the market's real concern. Gamma explains likely hedging pressure after price moves; it does not by itself explain whether the headline was accepted or rejected.

Gamma Reading Rules

• gamma wall: a price where positive GEX is concentrated; price often slows, pins, or rejects there.
• gamma flip: estimated transition between positive and negative gamma regimes.
• vol trigger: treat as the practical gamma/volatility regime divider. Below it, expect more reflexive/high-volatility behavior; above it, expect repair or pinning if price also holds support.
• call wall: upside pressure/pinning zone first, breakout target second. Do not treat a distant call wall as bullish confirmation until spot reclaims the nearest trigger/resistance.
• put wall: downside support first, acceleration risk after it breaks. Do not treat large put OI as automatically bearish while spot is holding above the wall.
• vanna: estimated change in option delta as IV changes. Moomoo usually provides enough inputs to compute it even when it does not provide a direct option_vanna field.
• VEX: aggregate vanna exposure by strike. Use it to identify where IV crush/IV expansion can force meaningful delta adjustment; do not treat it as a standalone direction signal.
• Positive gamma: more chop/pinning/mean-reversion; avoid chasing into walls without confirmation.
• Negative gamma: more trend amplification; be quicker with stops and avoid casual dip-buying.
• Low-gamma trough: path of least resistance; price may move faster through it.
• Vanna pressure matters most around macro/news vol crushes, 0DTE IV resets, and strong spot moves that also reprice IV. Report the top positive and negative vanna zones alongside gamma walls.

SPX, SPY, And ES Point Conversion

When analyzing SPX with proxy instruments, never hard-code a fixed 10x conversion:

• Prefer .SPX option chains from moomoo as US..SPX when available. Moomoo may reject the SPX index snapshot while still allowing SPX/SPXW option expiries and chains.
• Do not assume OpenD can provide US..SPX real-time 1-minute K-lines. Some OpenD environments can return 暂不支持美股指数 for US..SPX SubType.K_1M / get_cur_kline. For SPX intraday price-action confirmation, use US.SPY 1-minute K-lines as the chart proxy: reuse the existing US.SPY SubType.K_1M subscription when it is still valid; if K-line retrieval says subscription is missing or stale, subscribe/re-subscribe and retry once. Then convert the relevant SPY prices to SPX-equivalent levels with the freshest SPX/SPXW parity anchor or live ES/SPX anchor. State that SPY is the K-line source.
• Treat user requests for SPX, SP500, S&P 500, or 标普500 gamma as SPX-index-option requests by default. Query US..SPX expiries/chains first and use the returned SPX/SPXW strikes directly; do not default to SPY options just because the SPX index snapshot is unavailable.
• When US..SPX chains are available, do not use SPY conversion for SPX/SP500 gamma. SPY/ES/CFD conversion is only a fallback when the SPX/SPXW chain is unavailable, permission-blocked, or user-provided data is explicitly proxy-based.
• For same-day intraday/0DTE gamma, prefer PM-settled SPXW contracts from the US..SPX chain. On dates that also list AM-settled monthly SPX contracts, exclude the AM-settled series from the intraday pin/gamma map unless the user specifically asks about AM settlement.
• Use live SPX/ES/CFD price as the spot anchor for index levels, then use SPX option strikes directly whenever possible.
• If using SPY options as a proxy, compute the same-day conversion ratio from simultaneous prices: SPX_equiv = SPY_strike * (current_SPX_or_ES_anchor / current_SPY_price).
• If using ES as the price anchor, remember ES can trade at a futures basis versus SPX cash. State the anchor and basis explicitly, e.g. “SPY 734 with ES/SPX anchor 7355 implies ratio about 10.02 today.”
• If live SPX/ES is unavailable, an external SPX/SPY ratio such as prior close from Yahoo Finance, Investing.com, Barchart, or another current quote source can be used as an approximate fallback. Clearly state the source/time and that it is not a live simultaneous conversion.
• Recompute the ratio every session and after large moves; do not carry yesterday's ratio into today's levels.

Nikkei / EWJ Proxy Conversion

• Treat Nikkei, 日经, 日経, NKY, Nikkei 225, and 日经225 gamma requests as index-proxy work, not a plain EWJ ETF gamma request.
• Use US.EWJ options as the proxy book only because moomoo may not provide the domestic Nikkei option chain. The conversion must be time-aligned: Nikkei_equiv = EWJ_strike * (NKD_at_EWJ_quote_time / EWJ_quote_spot) * (current_NIY_or_CFD_anchor / current_NKD).
• After the US regular/options session has closed, exclude EWJ contracts that expired on that US trading date from any forward-looking Japan-session gamma map. Use only still-open expiries, normally the next listed weekly/monthly expiry such as 2026-05-29 and later. Same-day expired EWJ contracts are useful only for analyzing that US session before expiry, not for the next Japan session.
• Prefer NKDmain as the bridge because it is the USD Nikkei futures line closer to the US/EWJ session. Use NIYmain or the user's Nikkei CFD/index quote as the final current anchor when available.
• If EWJ has already closed, do not pair its closing price with the current Nikkei CFD directly. Use the Nikkei futures/CFD value at EWJ's quote timestamp to form the EWJ-to-NKD ratio, then bridge from current NKD to current NIY/CFD.
• If using Japan cash close as the anchor, pair it only with an EWJ overnight/24h quote from the same timestamp. If no real EWJ quote exists at Japan close, do not mix Japan cash close with the later US regular-session EWJ close.
• Moomoo may recognize US.NKDmain and US.NIYmain but return permission errors. If that happens, ask the user for: NKD at EWJ close/update time, current NKD, and current NIY or Nikkei CFD.
• If time-aligned anchors are una
