PA Hunter

PA Hunter detects 13 classical Price Action patterns on any symbol and timeframe, filters them using built-in context rules and an AI model trained on real historical signals.

How It Works

The indicator scans price data for the following patterns:

Reversal patterns: Pin Bar, Engulfing, Morning Star, Evening Star, Railway Tracks, Tweezer Tops/Bottoms, Piercing Line, Dark Cloud Cover, Three Soldiers, Three Crows

Continuation/Neutral: Inside Bar, Doji, Marubozu

Each detected signal passes through a multi-layer filter system before being displayed on the chart.

Signal Quality Score (0–7 stars)

Every signal receives a quality score based on seven criteria:

• Proximity to Support/Resistance zone
• S/R zone confluence (swing + volume)
• EMA trend alignment
• Candle size relative to ATR
• Tick volume confirmation
• Multi-timeframe EMA agreement
• Position in price range

Support and Resistance Zones

The indicator automatically identifies two types of zones:

• Swing zones — based on swing highs and lows
• Volume zones — based on horizontal volume clusters

When both methods confirm the same level, the zone is marked as a confluence zone with higher strength rating.

AI Filter (ONNX)

An embedded LightGBM model trained on 9,000+ real historical signals filters out low-probability setups. The model analyzes pattern type, market context, time of day, volatility and trend direction.

At confidence threshold 0.55, historical win rate on test data: 82%

The AI model can be disabled to view all signals without filtering.

Statistics Dashboard

A movable statistics panel displays real-time signal performance:

• Win rate per pattern type
• Visual progress bars
• Total signals evaluated
• Average signal score

The panel can be dragged to any position on the chart and remembers its location across sessions and timeframe switches.

TP/SL Levels

Each signal displays three horizontal lines:

• Blue solid — entry level (pattern close price)
• Green dashed — take profit (calculated per pattern logic)
• Red dotted — stop loss

Take profit levels are calculated using classical Price Action rules specific to each pattern type.

Smart Filters

• Filter small candles (noise) — removes signals on candles smaller than average
• Only signals at swing extremes — shows signals only at local price extremes
• Bars for swing extreme detection — lookback period for swing detection
• EMA trend alignment filter — requires signal direction to match EMA trend
• EMA period — period for trend EMA (50 recommended)
• Bull only after downmove, Bear after upmove — trend context filter
• Bars to determine trend context — range for context analysis
• Minimum signal score to display — filters out low-quality signals (0–7)
• Maximum bars to analyze — limits historical scan depth

Support and Resistance Zones

• Show S/R zones on chart — enable/disable zone display
• Bars for swing high/low detection — swing detection window
• S/R zone lookback depth — how far back to search for zones
• Volume profile bars — bars used for volume analysis
• Zone merge distance — merges nearby zones within N × ATR
• Zone transparency — visual transparency of zones
• Zone border width — border line width
• Show only strong zones — display only zones with strength 3+

AI Filter (ONNX)

• Enable AI signal filter
• AI model filename — file must be placed in MQL5/Files/ folder
• AI confidence threshold — signals below this value are not displayed
• Show AI probability on signal labels

Alerts

• Alert mode — None / Popup / Push / Both
• Alert only on newly formed signals
• Minimum score to trigger alert

Installation

1. Copy PA_Hunter.mq5 to MQL5/Indicators/ folder
2. Copy all .mqh files to MQL5/Include/ folder
3. Copy pa_hunter_model.onnx to MQL5/Files/ folder
4. Attach the indicator to any chart

The AI model file (pa_hunter_model.onnx) must be present in the MQL5/Files/ folder for the AI filter to work. Without it, the indicator operates in standard mode displaying all filtered signals.
