The Expert Advisor coded for EURUSD and GBPUSD pairs runs on M15 timeframe.
This is a scalper strategy. The EA trades are based on volatility.
The basic setup is running with risk 5.0. You can modify any time the risk factor, if you need. But you have to consider that increasing the risk factor resulting in a higher profit will increase the drawdown as well.
The EA is dynamically modifying the trade size according to the money management. Turning off the money management you can set manually the LOT size.
This Expert Advisor works great on ECN or low spread account (no more than 3 pips).
