Bollinger with WPR scalper

The Expert Advisor trades based on Bollinger bands and Williams` Percent Range. It also uses other indicators. It can perform a lot of trades, so you don't need to wait for new positions (with appropriate settings and with the H1 timeframe). The EA has the trailing stop and stop loss calculation functions depending on the currency pair movement strength.

The EA can be used on any currency pairs and timeframes from M5 to D1. Do not forget to optimize parameters.‌‌
