Exp_ColorMETRO_MMRec_Duplex - expert for MetaTrader 5

Two identical trading systems (for long and short deals) based on the ColorMETRO indicator signals that can be configured in different ways within a single EA with an ability to change the volume of a forthcoming trade depending on the results of the previous trades for this trading system. The Expert Advisor is a result of further development of the Exp_ColorMETRO_Duplex trading system, the aim of which was to enable changing of the volume of opened positions.

The following Expert Advisor input blocks have been added for that purpose:

input uint    L_TotalMMTriger=5;    //L number of the last Buy deals to calculate stop loss
input uint    L_LossMMTriger=3;     //L number of losing Buy deals to reduce MM
input double  L_SmallMM=0.01;       //L Share of a deposit in a deal in case of loss
input double  L_MM=0.1;             //L Share of a deposit in a deal during normal trading
input MarginMode L_MMMode=LOT;      //L lot setting mode

and

input uint    S_TotalMMTriger=5;    //S number of the last Sell deals to calculate stop loss
input uint    S_LossMMTriger=3;     //S number of losing Sell deals to reduce MM
input double  S_SmallMM=0.01;       //S Share of a deposit in a deal in case of loss
input double  S_MM=0.1;             //S Share of a deposit in a deal during normal trading
input MarginMode S_MMMode=LOT;      //S lot setting mode

In case of such inputs and when selecting from the last five trades, three of which are loss-making in a single direction, the EA opens the next trade in the same direction having the volume of 0.01 lot. If there are less than three loss-making trades out of the last five ones, the position volume is 0.1.

For the Expert Advisor to operate, you should place the compiled ColorMETRO.ex5 indicator files to <terminal_data_directory>\MQL5\Indicators.

The EA default input parameters were used in tests below. Stop Loss and Take Profit were not used in testing.
