Bands trend

This trend Expert Advisor is based on an original interpretation of the Bollinger Bands indicator. This signal generation method allows entering the market at the very beginning of the trend with a tight stop loss.

The EA contains 6 options for position closure signals, which allows selecting the best one depending on the instrument, as well as market conditions. All positions are protected by virtual and fail-safe stop loss. The virtual stop loss triggers only after a bar closes beyond its level, as in the Interactive Stop Loss utility,protecting the position from closure at sharp price spikes. The fail-safe stop loss limits the losses if the price spike is too large. The virtual stop loss can be disabled in the settings, and the EA will only use the regular stop loss. As soon as the price starts reverting in the unprofitable direction, the EA moves the stop loss to the breakeven level, which prevents the position from closing with a loss in case of a sudden price reversal. The volume can be managed using any of the 3 functions. These include a static lot, lot based on risk management and lot proportional to the free margin (equity). Also, the EA has a limit on the trading time. This is a limit by the months of the year, the days of the month, the days of the week. As well as the standard trading sessions — European, Asian and American. The EA provides a feature to set a custom trading session time. Time in the expert is set by Greenwich Mean Time.
