Master Bollinger Extended 外汇EA

This Expert Advisor is an improved version of Master
Bollinger Bands and has more settings; it can set stop loss per parabolic. Added parameters to improve optimization (for example,
to discard profitable settings, but with a small number of transactions).

Like the regular version, the adviser can close positions by a return signal, take profit and stop loss, set the transaction to breakeven
when it reaches the center line of Bollinger or at a given value. It can use up to 3 Bollinger indicators and a filter by moving average
indicators (described in more detail in the main version).
