# Trading Analysis > Analyze A-share money flow from tick-level data using the trading-analysis CLI, with both historical and real-time modes. Use this skill whenever the user mentions money flow, capital flow, main force inflow/outflow, institutional buying, tick-level analysis, order size classification (super-large/large/medium/small orders), real-time monitoring of capital flow, or wants to know whether smart money is buying or selling a stock. Also use when the user asks about 资金流向, 主力资金, 大单, 超大单, 散户, 逐笔分析, or 实时监控. - Skill: `oopslink/trading-analysis` (Agent Skill) - Install (CLI): `npx skillmds@latest add oopslink/trading-analysis` - Raw SKILL.md: https://api.skillmd.com/api/skills/oopslink/trading-analysis/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: oopslink (https://skillmd.com/u/oopslink) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/oopslink/trading-analysis --- # trading-analysis: Tick-Level Money Flow Analysis ## Architecture ``` trading-analysis CLI | v miniqmt_cli.client.transport (HTTP) | v miniqmt-cli daemon (Windows, port 8765) | v xtquant tick snapshots (3-second intervals) ``` Requires: miniqmt-cli daemon running + SSH tunnel active. Verify with `miniqmt-cli health` before use. ## How It Works 1. Fetches 3-second tick snapshots from the daemon (`/data/ticks`) 2. Diffs adjacent snapshots to get per-interval delta (amount, volume, trade count) 3. Classifies direction: `lastPrice >= ask1` = active buy, `<= bid1` = active sell, else neutral (split 50/50) 4. Hybrid tier assignment: `avg_amount = delta_amount / delta_trades` determines tier, `delta_amount` is accumulated 5. Aggregates buy/sell/net per tier, computes main force net (xlarge + large) and retail net (medium + small) ## Tier Thresholds (Default) | Tier | Average Per-Trade Amount | Label | |------|-------------------------|-------| | Extra-large | >= 100 wan (1,000,000) | 超大单 | | Large | 20 ~ 100 wan | 大单 | | Medium | 4 ~ 20 wan | 中单 | | Small | < 4 wan | 小单 | Thresholds are configurable via `--thresholds`. ## Commands ```bash # Single stock, today, full trading day trading-analysis moneyflow --code 002028.SZ # Specify date (historical) trading-analysis moneyflow --code 002028.SZ --date 20260416 # Custom time range trading-analysis moneyflow --code 002028.SZ --start 093000 --end 110000 # Multiple stocks (outputs per-stock tables + ranking) trading-analysis moneyflow --code 002028.SZ --code 000859.SZ --code 300618.SZ # JSON output trading-analysis moneyflow --code 002028.SZ --format json # Custom thresholds (wan): small/medium boundary, medium/large, large/xlarge trading-analysis moneyflow --code 002028.SZ --thresholds 4,20,100 # Use specific miniqmt-cli client config trading-analysis moneyflow --code 002028.SZ --config ~/.miniqmt_cli/client.toml ``` ### Real-time Mode (--live) Polls the daemon for latest tick snapshots every N seconds, accumulates deltas into a running summary, and displays via Rich Live (in-place terminal refresh). Ctrl+C to stop; prints final summary on exit. ```bash # Single stock real-time (default 10s refresh) trading-analysis moneyflow --code 002028.SZ --live # Multiple stocks real-time ranking trading-analysis moneyflow --code 002028.SZ --code 000859.SZ --code 300618.SZ --live # Custom refresh interval (30 seconds) trading-analysis moneyflow --code 002028.SZ --live --interval 30 ``` - Single stock: full four-tier table, updated in-place - Multiple stocks: compact ranking table sorted by main force net inflow - Requires market hours for meaningful data; outside trading hours the display will show zeros - Combine with `--signal` to get alert-on-trigger behavior; see **Signal Expressions** below. ## Signal Expressions (`--signal`) Live mode supports a minimal expression language for triggering alerts when conditions are met. The expression is evaluated every refresh interval against the running per-stock state. ```bash # Alert when main force is net buying AND price is above MA20 trading-analysis moneyflow --code 002028.SZ --live \ --signal "main_net > 0 and price > ma20" # Alert on a reversal signal trading-analysis moneyflow --code 002028.SZ --live \ --signal "main_net > 500000 and ma5 > ma20" # Multiple stocks — signal is evaluated per code independently trading-analysis moneyflow --code 002028.SZ --code 000859.SZ --live \ --signal "main_net > 0" ``` **Variables** (all in yuan unless noted): | Variable | Meaning | |----------|---------| | `main_net` | Main force net inflow (xlarge + large tiers) | | `retail_net` | Retail net inflow (medium + small tiers) | | `price` | Latest tick `lastPrice` | | `ma5` / `ma10` / `ma20` / `ma60` | Simple moving average of that many 1-minute closes | **Operators**: `>`, `<`, `>=`, `<=`, `==`, `and`, `or` (lowercase only). **Literals**: integers and floats; numbers are in yuan (e.g. `500000` = 50 wan). **Semantics**: - If any referenced variable is `None` (e.g. MA window not yet filled), the signal is **not triggered** — no false positives during warm-up. - MA windows are auto-detected from the expression; `ma20` triggers a preload of 20 1-minute klines before the live loop starts. - Trigger flips edge-sensitive: the alert fires once when `False → True`. It re-arms when the expression goes back to `False`. **Output**: when triggered, the live display prints a red banner `>>> 002028.SZ 信号触发: <<<` and the footer shows "已触发: [codes]". On Ctrl+C exit, a final summary lists which codes ever triggered. **Limitations**: - No parentheses — precedence is strictly `cmp → and → or` with left-to-right evaluation. - No arithmetic (`+`, `-`, `*`, `/`) inside expressions — compare variables to literal thresholds only. - No historical lookback beyond the MA window (no "price N minutes ago"). ## Parameter Reference | Parameter | Default | Format | |-----------|---------|--------| | `--code` | (required, multiple) | `XXXXXX.SZ` / `XXXXXX.SH` | | `--date` | today | `YYYYMMDD` | | `--start` | `093000` | `HHMMSS` | | `--end` | `150000` | `HHMMSS` | | `--format` | `table` | `table` / `json` / `csv` | | `--thresholds` | `4,20,100` | comma-separated wan | | `--config` | from miniqmt-cli client.toml | path | | `--live` | off | flag | | `--interval` | `10` | seconds | ## Output Example ``` 002028.SZ 2026-04-16 09:30 ~ 15:00 ────────────────────────────────────────────────── 档位 买入(万) 卖出(万) 净流入(万) 方向 超大单 1,230.5 480.2 +750.3 净流入 大单 860.1 920.3 -60.2 净流出 中单 340.7 290.1 +50.6 净流入 小单 180.3 210.8 -30.5 净流出 ────────────────────────────────────────────────── 主力合计 +690.1 净流入 散户合计 +20.1 净流入 统计: 快照 4,800 条 | 有效区间 4,799 | 买入 2,103 | 卖出 2,288 | 中性 408 ``` Multiple stocks append a ranking: ``` ── 主力净流入排名 ── #1 002028.SZ +690.1万 #2 300618.SZ +120.3万 #3 000859.SZ -45.2万 ``` ## Interpreting Results - **主力合计 > 0**: Main force (institutions/large traders) net buying -- bullish signal - **主力合计 < 0**: Main force net selling -- bearish signal - **超大单 dominant**: Likely institutional activity - **大单 dominant without 超大单**: Could be large retail or small institutional - **All activity in 小单/中单**: Retail-driven, no clear institutional signal ## Troubleshooting | Symptom | Cause | Fix | |---------|-------|-----| | "cannot reach daemon" | SSH tunnel or daemon down | `miniqmt-cli health`; restart tunnel/daemon | | "无数据" | Non-trading hours, invalid code, or no cached data | Check code format, try during market hours | | All tiers show 0 | No trading activity in the time range | Widen the time range | | 大单/超大单 always 0 | 3-second avg too small to hit threshold | Lower thresholds: `--thresholds 2,10,50` | | Live mode shows all zeros | Outside trading hours, no new ticks | Run during market hours (09:30-15:00) | | Live mode not updating | Daemon not returning fresh snapshots | Check `miniqmt-cli health`; ensure miniQMT client is open | ## Related Skills - **miniqmt-cli** — The daemon and data source underneath; the only supported way to reach the trading daemon
