User Manual – Omega Pattern Trader
1. Overview
Omega Pattern Trader is an automated MT5 Expert Advisor (EA) designed to trade based on
Harmonic Patterns (Gartley & Bat) combined with:
• Support/Resistance filtering
• RSI confirmation
• ATR-based Stop Loss, Take Profit, and Trailing Stop
This EA aims to capture high-probability reversal points at the completion of Gartley or Bat
patterns (point D) with additional confirmation from RSI and price zones.
2. Core Logic
1. Pattern Detection
o Uses ZigZag to find swing points (X, A, B, C, D).
o Tests ratios to identify Gartley (AB≈0.618 XA, D≈0.786 XA) or Bat
(AB≈0.382–0.50 XA, D≈0.886 XA) patterns.
2. Support/Resistance Filter
o Confirms that point D is close to a recent high (for sell) or low (for buy).
3. RSI Confirmation
o Buy only if RSI ≤ RSI_Buy_Thresh.
o Sell only if RSI ≥ RSI_Sell_Thresh.
4. Risk & Trade Management
o SL = ATR × StopATR_Multiplier, anchored from point D.
o TP = Risk/Reward ratio (TP_RR × SL distance).
o Trailing stop based on ATR.
o Position size can be fixed lot or risk-based lots (% of free margin).
3. Input Parameters
General Trade Settings
• UseRiskPercent – true = risk-based lot size, false = FixedLot.
• RiskPercent – % of free margin risked per trade.
• FixedLot – lot size if not using risk %.
• Magic – unique trade identifier.
Stop Loss & Take Profit• StopATR_Multiplier – ATR multiplier for Stop Loss distance.
• TP_RR – Take Profit as multiple of SL (Risk/Reward ratio).
• EnableTrailing – enable ATR trailing stop.
• TrailATR_Multiplier – trailing stop distance in ATR multiples.
Pattern Detection
• ZigZagDepth / Deviation / Backstep – ZigZag settings to detect swing points.
• RatioTolerance – % tolerance allowed for harmonic ratio validation.
RSI Filter
• RSIPeriod – RSI calculation period.
• RSI_Buy_Thresh – max RSI for bullish confirmation (default 40).
• RSI_Sell_Thresh – min RSI for bearish confirmation (default 60).
Support/Resistance
• SR_Period – number of bars to check highs/lows.
• SR_Tolerance_Pips – max pip distance allowed from S/R to D.
ATR Settings
• ATR_Period – period for ATR calculation.
Execution
• OneTradePerBar – if true, EA evaluates once per new bar; if false, checks every tick
(with last closed bar data).
4. Recommended Presets
EURUSD – M15
• ZigZagDepth = 12
• RSIPeriod = 14
• RSI_Buy_Thresh = 40
• RSI_Sell_Thresh = 60
• StopATR_Multiplier = 2.0
• TP_RR = 1.2
• RiskPercent = 1.0
XAUUSD (Gold) – H1• ZigZagDepth = 24
• RSIPeriod = 14
• RSI_Buy_Thresh = 35
• RSI_Sell_Thresh = 65
• StopATR_Multiplier = 2.5
• TP_RR = 1.5
• RiskPercent = 0.5
5. Tips for Best Performance
• Use on high-liquidity pairs (EURUSD, GBPUSD, XAUUSD).
• Avoid news spikes – patterns often fail in high volatility events.
• Test on different timeframes – M15 for scalping, H1 for swing trades.
• Optimize ATR multipliers & RSI thresholds per instrument.
6. Limitations
• Pattern detection depends on ZigZag swings – repainting may occur.
• EA does not detect other harmonic types (e.g., Butterfly, Crab).
• Works best in trending or corrective markets, may struggle in choppy sideways ranges.
