Technical Analysis

Technical Analysis

When to use

Activate when a user wants a technical read on a DSE stock: "analyze the chart for GP", "is BEXIMCO technically bullish?", "what do RSI and MACD say?", "run technical analysis". This skill is the technical leg of the dual-mode signal — pair it with momentum-screen for trade setups, or feed its score into signal-synthesizer.

What it does

Implements the six-member Technical Committee plus a Chair (PRD-002 FR-AG-2, FR-AG-13..18):

1. Trend — 50/150/200 SMA stack, price vs 200-day, ADX trend strength (+DI/-DI).
2. Momentum & Oscillator — RSI(14), MACD, ROC(12), MFI(14).
3. Chart Pattern — breakout/breakdown vs 40-bar range, consolidation tightness.
4. Candlestick — hammer, shooting star, bullish engulfing on the latest bars.
5. Levels — 60-bar support/resistance, distance-to-support, range position.
6. Volume & Flow — OBV slope (accumulation/distribution), relative volume vs 20-day avg.

The Chair aggregates members with the weights in scripts/analyze.py (WEIGHTS), notes agreement vs conflict (e.g. "pattern bullish but volume not confirming → downgraded"), and downgrades confidence when members disagree. Output is a Thinking Card (see suite README).

How to run

# input must follow the suite data contract and include at least 30 OHLCV bars
python3 scripts/analyze.py --input data.json --pretty
cat data.json | python3 scripts/analyze.py

Reads ohlcv (required, ≥30 bars; ≥200 for full MA stack), optional microstructure (flags circuit-limit / floor-price conditions) and mode. Returns score (-1..+1), confidence (0..1), rating, sub_scores per member, key_metrics, and reasoning.

Try it now with the shared fixture:

python3 scripts/analyze.py --input ../_fixtures/sample_input.json --pretty

Interpreting output

• score ≥ 0.5 strong_bullish, 0.15..0.5 bullish, -0.15..0.15 neutral, etc.
• Low confidence with a chair_note about conflict means members disagree — treat as "stand aside" rather than a weak buy.
• flags carry confidence penalties (e.g. limited_history_<200_bars, microstructure_circuit_or_floor) — never silently dropped.

Notes

Indicator math lives in scripts/indicators.py (pure Python, reusable). Formula definitions and DSE-specific caveats are in references/INDICATORS.md. Output is educational analysis only, never financial advice.
