Modification of grid EA

Hi to all,

I need a modification of an existing grid EA with the following instructions:

Add the following optional external inputs to the attached Expert Advisor:

                                                    input bool          TradeModeAgainstTrend (TMAT) = true;
input int           CounterTrendLotsToStartTMAT = 0.15;
input double        CoefficientForTrendLots = 0.30;
input double        MaxTrendLot = 0.08;
input bool          OneSideTMATOnly = true;
input double        CombinedClosureAmount = 10.0;

Explanation:

If TradeModeAgainstTrend (TMAT) is set to true, enable a mode where, for example:

• Once the total volume of open Buy positions exceeds CounterTrendLotsToStartTMAT (e.g., 0.15 lots), the next Sell position is opened with a lot size equal to CoefficientForTrendLots (e.g., 30%) of the total lots of the currently open Buy positions, but not exceeding MaxTrendLot. If MaxTrendLot = 0, then no maximum lot size restriction should be applied.
• After the Buy basket in our example is completely closed according to the original EA logic, TMAT should be reset, and the next Sell position should start again from 0.01 lots.
• If OneSideTMATOnly is set to true:
  • If Buy lots ≥ the specified limit, only Sell positions should increase.
  • If Sell lots ≥ the specified limit, only Buy positions should increase.
  • Both sides must never increase simultaneously.
• If CombinedClosureAmount is not equal to 0, all currently open Buy and Sell orders should be closed simultaneously once their combined profit reaches the specified dollar amount (CombinedClosureAmount), and TMAT should then be reset.
