Bollinger And TrendLines

The Expert Advisor is based on Bollinger bands and trend lines. When the price touches the lower line of the Bollinger bands and goes back or rolls back from one or several trend lines, a buy is performed. The same is true for selling. The EA can also use two Bollinger bands indicators, so that a trade is performed between the lines of the two indicators with different deviations. The EA features many other settings. For example, a trade can be moved to a breakeven only when touching the central Bollinger band and passing a certain number of points.

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