ntaffzii Exposure Coach
Overview
A daily market check produces several separate numbers (breadth %, uptrend %, account drawdown state) — this skill combines them into one plain-language read: how much new risk today's conditions support. It's the synthesis step at the end of a market-regime check, not a replacement for the individual skills that feed it.
Not financial advice. This is one configurable heuristic for summarizing market conditions plus your own account's risk state — not a signal to act on mechanically, and not a substitute for judgment about the specific setup in front of you.
When to use
- สรุปภาพรวมตลาดหลังเช็ค breadth และ uptrend แล้ว ว่าวันนี้ควร "เปิดรับความเสี่ยงใหม่" มากแค่ไหน
- Combining a market-regime read with the account's own drawdown state into one exposure-ceiling recommendation
- The synthesis step of a daily/weekly market check (after running market-breadth-analyzer and uptrend-analyzer)
When NOT to use
- Breadth/uptrend numbers haven't been computed yet — run those skills first; this skill has nothing to combine without them
- The user wants a signal for one specific stock — this is a market-wide/account-wide posture read, not a single-name call
Core knowledge
Priority rule: the account's own drawdown state always overrides a favorable market read. A "halt_new_positions" drawdown-gate state produces a "minimal" exposure ceiling regardless of how strong breadth/uptrend look — a personal risk rule isn't meant to be overridden by good market conditions. A "reduced_size" gate state caps the market-derived ceiling one notch lower.
Market-derived ceiling (before any drawdown adjustment):
| Breadth % | Uptrend % | Ceiling |
|---|---|---|
| ≥ 60% | ≥ 50% | High |
| ≥ 40% | ≥ 30% | Moderate |
| below both | — | Low |
These thresholds are a starting heuristic, not a validated model — like the individual skills feeding it, tune them against the user's own strategy history rather than treating them as fixed truth.
Common mistakes
- Treating "high exposure ceiling" as "take every setup available" — it means the market backdrop doesn't argue against new risk, not that any specific trade is good.
- Letting a favorable market read override an active drawdown-gate halt — the priority order matters and is intentional (see Core knowledge).
- Running this skill with stale or mismatched-date breadth/uptrend inputs — the synthesis is only as current as its inputs.
- Treating the ceiling as a percentage of capital to deploy — it's a qualitative posture label (high/moderate/low/minimal), not a sizing formula; use position-sizer for the actual per-trade math.
Code
posture.py — pure logic, no dependencies:
evaluate_posture(breadth_pct, uptrend_pct, drawdown_action="full_size")→PostureResult(exposure_ceiling, reasons)
Run python3 posture.py for the self-test.
Known limitations
- Thresholds are illustrative defaults, not calibrated against any specific strategy or universe — recalibrate before relying on them.
- Only combines the three inputs listed — doesn't account for other regime signals (volatility index level, sector rotation, macro calendar) a fuller market-regime process might use.
- This is a rule-based summary, not a probabilistic forecast — it describes current conditions, not future returns.
