The Exp_StepSto_v1 trading system is drawn on the basis of the signals of the StepSto_v1 stochastic oscillator. A signal to perform a deal is formed at bar closing. To make deals the location of a purple, signal line of the indicator is used as a filter. If the signal line is higher than 50, the Expert Advisor can open only longs and close only shorts, if the signal line is below 50, then only shorts are opened and longs are closed. The signal to perform a deal is the breakdown of the orange indicator line by purple, signal line in the corresponding direction.
