Developer finished my EA perfectly on the first try. Works exactly as requested and I’m very happy with the results. Highly recommended!

Tarea técnica

I already have an MT5 EA developed, but it has an error in the lot size calculation for loss recovery. I need an experienced MQL5 coder to modify the existing EA to implement the correct lot size recovery logic.


What I need:


  • Fix the lot size calculation so the EA increases lot size correctly after a losing trade to cover the previous loss plus the fixed profit target.
  • Lot size must be calculated using this formula:
    LotSize = (PreviousLoss + ProfitTarget) / (TakeProfitPips * PipValue)
  • Take profit pips remain fixed; only lot size changes.
  • After recovering losses and hitting the profit target, lot size resets to the default base lot.
  • The EA trades only one position at a time based on existing signals or EMA crossover logic.
  • The EA currently has an option to limit the number of trades opened simultaneously — this feature should be maintained or fixed if necessary.
  • Please follow the formula and logic precisely; no guessing.



If you have experience fixing/modifying money management and trade control in MT5 EAs, please get in touch.
