//| SimpleFVG EA – Pure Fair Value Gap Strategy |
|
||||
//| |
|
||||
//| Logic: |
|
||||
//| 1. Scan 3-candle pattern: gap between High[i+2] and Low[i] |
|
||||
//| 2. Bullish FVG: High(candle1) < Low(candle3) + strong candle2 |
|
||||
//| 3. Place Buy Limit at FVG upper edge (Low of candle3) |
|
||||
//| 4. SL = Low(candle1), TP = entry + 2R |
|
||||
//| 5. Invalidation: close below FVG or timeout |
|
||||
//| |
|
||||
//| Bearish FVG: mirror logic |
|
||||
//| SimpleFVG.mq5 – Fair Value Gap Visual Strategy (Test mode) |
|
||||
//| |
|
||||
//| Modules: |
|
||||
//| Config.mqh → Step 0: Inputs, enums, constants |
|
||||
//| Trend.mqh → Step 1: EMA34/EMA89 trend detection |
