Exp_ColorXPWMA_Digit_NN3_MMRec - MetaTrader 5 için Uzman Danışman

Three independent trading systems using ColorXPWMA_Digit indicators 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. Trading signals are formed when a bar closes if a trend has changed (which is displayed by any of the three indicators changing its color).

The blocks of input EA variables are added for managing volumes of opened positions. For example, for the first system:

input uint    A_BuyTotalMMTriger=5; //A number of the last Buy deals to calculate stop loss
input uint    A_BuyLossMMTriger=3;  //A number of losing Buy deals to reduce MM
input uint    A_SellTotalMMTriger=5;//A number of the last Sell deals to calculate stop loss
input uint    A_SellLossMMTriger=3; //A number of losing Sell deals to reduce MM
input double  A_SmallMM=0.01;       //A share of a deposit in a deal in case of loss
input double  A_MM=0.1;             //A share of a deposit in a deal during normal trading
input MarginMode A_MMMode=LOT;      //A 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.

The similar inputs are available for the second trading system:

input uint    B_BuyTotalMMTriger=5; //B number of the last Buy deals to calculate stop loss
input uint    B_BuyLossMMTriger=3;  //B number of losing Buy deals to reduce MM
input uint    B_SellTotalMMTriger=5;//B number of the last Sell deals to calculate stop loss
input uint    B_SellLossMMTriger=3; //B number of losing Sell deals to reduce MM
input double  B_SmallMM=0.01;       //B share of a deposit in a deal in case of loss
input double  B_MM=0.1;             //B share of a deposit in a deal during normal trading
input MarginMode B_MMMode=LOT;      //B lot setting mode

The C_ prefix is used in the inputs for the third system.

The most optimal option for setting up such an EA is configuring it on each trading system separately disabling other two applying the appropriate switches in the form of the following parameters:

input bool    B_BuyPosOpen=true;    //B permission to enter long positions
input bool    B_SellPosOpen=true;   //B permission to enter short positions

by setting them to false.

For the generated EA to operate correctly, the compiled ColorXPWMA_Digit.ex5 indicator file must be available under the <terminal_data_directory>\MQL5\Indicators folder.
