The SpearmanRankCorrelation_Histogram indicator with the ability to send alerts, emails and push notifications when trading signals emerge. Possible signal options:

• Zero breakthrough by the histogram;
• Overbought or oversold levels breakthrough;
• Exiting overbought or oversold areas.
  

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 SmoothAlgorithms.mqh library classes (copy it to terminal_data_folder\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".
