EMAplusWPR - expert for MetaTrader 4

ACTUAL VERSION : http://codebase.mql4.com/en/code/10413

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.

Inputs EMA, iWPRPeriod are optimized for EURUSD 5M

TakeProfit = 200;

maxStopLoss=50;

maxLots = 0.1; // max lots per position

maxContracts = 2; // max open positions, 2 is optimal for smoother equity

EMA=144; // EMA to determine trend

iWPRPeriod=46; // Williams' Percentage Range to determine buy/sell signals

Test is without position sizing, 0.1 lot size
