Expert advisor that trade in the trend of EMA and buy/sell signals get from Williams %R
I have tried to create an Expert advisor that could by traded with 1000 EUR starting equity and to minimize the drawdown. Hope you like it. I appreciate every feedback.
Optimized for EURUSD 5 min
I have removed some bugs, changed position sizing, you define the % of your account you want to risk on a single trade. I added simple trailing stop, if trailingStop = 0, then it is disabled.
You use it on your own risk. I am not responsible for your loss, you have to change, test and optimize it for your purpose.
Inputs:
extern double takeProfit = 200; // take profit extern double maxStopLoss = 50; // stop loss extern double maxLots = 10; // max lots per position extern double maxContracts = 2; // max open positions, 2 is optimal for smoother equity extern double EMA = 144; // EMA to identify trend extern int iWPRPeriod = 46; // Williams' Percentage Range to determine buy/sell signals int iWPRretracement = 30; // retracement of Williams' Percentage to allow next trade extern double trailingStop = 50; // trailing stop, use 0 to disable trailing stop extern int risk = 2; // % of account you want to risk on a trade extern double magicNumber = 13131;

To use my position sizing increase the maxLots size and define the risk - how many % of your account you want to risk on a single trade.
For position sizing I use the following code:
minAllowedLot = MarketInfo(Symbol(), MODE_MINLOT); //IBFX= 0.10 lotStep = MarketInfo(Symbol(), MODE_LOTSTEP); //IBFX= 0.01 maxAllowedLot = MarketInfo(Symbol(), MODE_MAXLOT ); //IBFX=50.00 balance = AccountBalance(); ilo = ((balance * risk / 100) / maxStopLoss); lots = NormalizeDouble(ilo, 0) * lotStep; if (lots < minAllowedLot) lots = minAllowedLot; if (lots > maxLots) lots = maxLots; if (lots > maxAllowedLot) lots = maxAllowedLot;
