This Expert Advisor is an improved version of the Swing Scalper Reversal. The trading strategy is the same, but the Pro version has the ability to use Martingale.

The Expert Advisor expects retracements after a strong market movement. As soon as a bar of a different color (opposite trend) appears, after a few bars of the same color the EA opens a trade. You can adjust the number of bars, at which a trade can be opened. If a stop loss was hit, and the MartingaleFactor is greater than 0, the lot size will be increased. Thus, the market reversal will "caught" not immediately, but after a few losses (the last lot will cover all those losses). Te maximum number of consecutive losses can be adjusted using the MartingaleStopAfter parameter. It is not recommended to set a high value, because in dangerous cases, there is a risk of being unable to get out of a losing series (due to insufficient funds on the account to open a large lot). It is recommended to use cent accounts for this EA (at least until it makes a sum large enough).

The EA can be used on the timeframes from M5 to H1, the currency pairs with low spreads should be selected. Do not forget to optimize the parameters before trading and after a certain time period.
