SR-RateIndicator indicator provides alerts, sends email and push notifications when overbought/oversold levels are broken through by the histogram.
Input parameters for activating signals:
input uint NumberofBar=1; // Bar number for the signal activation input bool SoundON=true; // Enable alerts input uint NumberofAlerts=2; // Number of alerts input bool EMailON=false; // Enable mailing the signal input bool PushON=false; // Enable sending the signal to mobile devices
The indicator uses the OneSideGaussian.mqh Gaussian algorithms library (should be copied to the terminal_data_folder\MQL5\Include).
