Exp_UltraMFI_MMRec - MetaTrader 5 Expert - MT4/MT5 Resources

Add input EA variable block for managing the trading volume of the opened position:

 Enter the unit purchase total MMTriger= 5 ; // The quantity of the last buy transaction to calculate the stop loss
Input unit buying loss MMTriger= 3 ; // Reduce the number of loss buying transactions of MM
Input unit Sell total MMTriger= 5 ; // The quantity of the last sell transaction to calculate the stop loss
Input unit Sell loss MMTriger= 3 ; // Number of losing sell transactions to reduce MM
Enter double the small MM_= 0.01 ; // Margin share when a loss occurs in the transaction
Enter double MM= 0.1 ; // Share of margin in a trade during normal trading
Enter the margin mode MMMode=LOT; // Lot size determination method

In the case of such inputs, when choosing from the last 5 trades (3 of which were losses in a single direction), the EA opens the next trade in the same direction with a volume of 0.01 lots. If the last 5 losing trades are less than 3, the position will be 0.1.
In order for the generated EA to run correctly, the compiled Ultra MFI.ex5 indicator file must be in the <terminal data directory>\MQL5\indicator folder.
During testing the default Expert Advisor's input parameters without stop loss were used, as shown below.
