As we all know Stochastic is mainly used for pullbacks and reversals. In the EA settings you will be able to enter any Stochastic settings you like to use (K, D periods and Slowing) . After that you will also need to enter the levels on which EA will react and enter the market.
If you enter lets say for example lowLevel = 20 and highLevel = 80, Stochastic EA will simply enter the market when the market price will be above 80 level or below 20 level (see picture). You can also reverse the EA so that Stochastic EA will enter the market at the same levels, but in reversed positions.
