Break The Bands EA v4.0 for MT5 (XAUUSD, 1H)

I need an Expert Advisor (EA) coded for MetaTrader 5 based on the following specifications:

• Objective: Autonomous trading on Bollinger Band breakouts, robust across trending and consolidating years.

• Architecture:

  • Max 1 open trade at a time

  • Ignore opposite signals if a trade is open

  • Spread filter: always execute

• Indicators (Custom):

  • Bollinger Bands (WMA, length 20, deviation 1.5, source: close)

  • ATR (WMA, length 14)

  • Tick Volume (MA length 20)

• Money Management:

  • Risk % of equity

  • Dynamic lot size calculation

  • SL = Entry ± (2 × ATR), TP = none initially

• Entry Rules:

  • Long: bullish candle covers MA and closes above it

  • Short: bearish candle covers MA and closes below it

• Stop Loss / Take Profit Management:

  • Adaptive SL/TP based on band hits and swing highs/lows (details provided above)
    

    Deliverables:
