The idea of the indicator

Two iStochastic (Stochastic Oscillator, STO) indicators - 'Fast' and 'Slow' (more precisely, the 'Main' lines of these indicators) in one subwindow. Areas are filled between lines. The level settings are included in the input parameters - it can be useful when used in an Expert Advisor and when visualizing in a strategy tester. Added Notifications when crossing lines (Sound, Alert, mail, push)
