Mql5官网 Percent range advisor 外汇EA

The Expert Advisor is based on Williams` Percent Range. The EA trades both during low volatility and a trend if MACD is enabled. Two Williams` Percent Range indicators can be used to enter a trade with different parameters, while the third one can be configured to close a trade. Besides, the EA has the trailing stop and stop loss calculation functions depending on the currency pair movement strength.
