    The following changes have been made to the indicator code in order to implement the alerts, email messages and push-notifications:

    1. Introduced new input parameters
      //---- Input variables for alerts 
      input uint NumberofBar=1;                    //Bar number for the signal
      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
      
    2. Added three new functions to the end of the indicator code: BuySignal(), SellSignal() and GetStringTimeframe()

            Bid+=Spread[index];
            string sAsk=DoubleToString(Ask,_Digits);
            string sBid=DoubleToString(Bid,_Digits);
            string sPeriod=GetStringTimeframe(ChartPeriod());
            if(SoundON) Alert("SELL signal \n Ask=",Ask,"\n Bid=",Bid,"\n currtime=",text,"\n Symbol=",Symbol()," Period=",sPeriod);
            if(EMailON) SendMail(SignalSirname+": SELL signal alert","SELL signal at Ask="+sAsk+", Bid="+sBid+", Date="+text+" Symbol="+Symbol()+" Period="+sPeriod);
            if(PushON) SendNotification(SignalSirname+": SELL signal at Ask="+sAsk+", Bid="+sBid+", Date="+text+" Symbol="+Symbol()+" Period="+sPeriod);

      string GetStringTimeframe(ENUM_TIMEFRAMES timeframe)
        {
      //----
         return(StringSubstr(EnumToString(timeframe),7,-1));
      //----
        }
      
    3. Added a couple of calls to BuySignal() and SellSignal() functions after the indicator calculation cycles in the OnCalculate() block
      //---     
         BuySignal("X2MA_Alert",ColorX2MA,1,rates_total,prev_calculated,close,spread);
         SellSignal("X2MA_Alert",ColorX2MA,2,rates_total,prev_calculated,close,spread);
      //--- 
      

    Where ColorX2MA is the name of the color index buffer for storing line color in the form of an index.

    It is assumed that the only one call to the BuySignal() and SellSignal() functions will be used in the OnCalculate() block of the indicator code.

    The indicator uses the classes of SmoothAlgorithms.mqh library (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”.
