I am looking for an experienced MetaTrader 4/5 Expert Advisor (EA) developer to create a trading system for the chart using modified Heiken Ashi candles.

Key Features of the EA:

• Chart Setup:

  • 1-minute timeframe with Heiken Ashi candles.
  • Double smoothing for Heiken Ashi candles:
    • 
      

• Entry Logic:

  • Start with an initial trade size of 0.2 lots.
  • Enter trades when a Heiken Ashi candle closes in the trend direction and breaks a trend line.
  • Re-entry: After stop loss is hit, re-enter based on the next confirmed trend direction and breakout.

• Stop Loss (SL):

  • The stop loss should be placed at the last swing close in the opposite trend direction.
  • Implement a dynamic stop loss
  • Break-even: Once the trade reaches a 1:1 risk-to-reward ratio, move the stop loss to break-even to protect from reversals.

• Take Profit (TP) and Trailing Stop:

  • Use a trailing stop that moves as the market moves in your favor to lock in profits.
  • 
    

• Lot Size Recovery After Loss:

  • If a trade results in a loss, increase the lot size for the next trade by 0.1 lots.
  • Example:
    • First trade (Loss): 0.2 lots → Next trade: 0.3 lots
    • Second trade (Loss): 0.3 lots → Next trade: 0.4 lots
  • Once a profit is made, covering all prior losses, the lot size should return to the original size (0.2 lots).

• Risk Management:

  • Dynamic position sizing based on 1-2% risk per trade, considering the distance to the stop loss.
  • Set maximum slippage to 1-2 pips to ensure accurate execution.
  • Break-even protection should be activated once the trade reaches a 1:1 risk-to-reward ratio.

• 
  

Requirements:

• Expertise in MetaTrader 4/5 and MQL4/MQL5.
• Proven experience in developing high-frequency trading strategies, especially for lower timeframes like the 1-minute chart.
• Knowledge of lot size recovery, dynamic stop loss, and trailing stop loss techniques.
• Ability to create an optimized EA that can adjust to various market conditions while ensuring strong risk management.

Deliverables:

• Fully functional EA with the specified features.
• Source code of the EA for further modification and optimization.
• Backtesting results showing the EA’s performance across different market conditions, particularly focusing on the 1-minute timeframe.
• User manual with installation and configuration instructions for the EA.
