WPR scalper with Martingale

The Expert Advisor is based on Bollinger bands, Williams' Percent Range and some other indicators. It features the martingale function increasing a lot after a loss. However, it should be used wisely in order not to seriously damage your deposit in case trading ends in a loss. You can set a small number of losses in a row, at which a lot increases, and (or) a small increase in a lot value. In this case, trading becomes safer, while the number of trades remains large enough. You can disable the martingale by MartingaleFactor=1 so that a lot is not increased after losses.
