An Expert Advisor based on Pine Script & MQL5 needed

Here is a brief requirement document for developing an MT5 Expert Advisor (EA) based on the provided UT Bot Alerts Pine Script:

📌 EA Requirement: UT Bot Alerts Strategy (MT5)

🔍 Strategy Overview

This Expert Advisor will replicate the logic of the UT Bot Alerts TradingView indicator using ATR-based trailing stop logic and Heikin Ashi (optional) input for trade signals. It generates buy/sell signals based on price crossing the trailing stop derived from ATR.

🎯 Entry Rules

• Buy Entry:

  • Price ( src ) is above the ATR trailing stop.

  • Price has crossed above the ATR trailing stop (i.e., crossover occurred).

• Sell Entry:

  • Price ( src ) is below the ATR trailing stop.

  • Price has crossed below the ATR trailing stop (i.e., crossunder occurred).

• Heikin Ashi Option:

  • If enabled, signals are calculated using Heikin Ashi candle close values.

🔄 Exit/Close Logic

• Optional trailing stop could be implemented using the same xATRTrailingStop level as a dynamic SL.

• Alternatively, user-defined take profit (TP) and stop loss (SL) levels can be added.

• Only one trade should be active at a time: before opening a new trade in the opposite direction, the current one must be closed.

⚙️ Inputs / Parameters

• KeyValue (a) : Sensitivity multiplier for ATR trailing stop (default: 1.0)

• ATRPeriod (c) : ATR period for trailing stop calculation (default: 10)

• UseHeikinAshi (h) : Boolean flag to use Heikin Ashi candles instead of regular price (default: false)

• LotSize : Fixed or dynamically calculated based on account balance (optionally enable compounding)

• MagicNumber : For identifying EA trades uniquely

• Slippage , MaxOrders , etc.: Standard trade management options

🔔 Alerts (Optional)

• Log/Comment when a buy/sell signal is detected.

🛠️ Additional Features 

• Trailing Stop: Dynamic SL adjustment following ATR logic.

• Dynamic Lot Size: Based on balance or risk percentage.

• Backtest Optimization Inputs: Allow tuning of ATR period, key value, and Heikin Ashi usage.
