The Martingale BB SMA EA trades by signals of the Simple Moving Average (SMA) and the Bollinger Bands (BB) indicators. The Stop Loss level for the first and next orders is set according to parameters of the BB indicator when you open the first position.

The trading volume used for opening positions depends on the following parameters: Value_of_one_lot; Digits_round_lots; Max_order; Risk_money_SL. Martingale system, which proportionally increases the trade volume according to set parameters, is applied when you open a trade.

The EA is optimized for EURUSD, M30. But with proper settings it is also appropriate for any time frames and any instruments.
