Hi Guys

 I have started creating an indicator with Email alert. Kind of stuck halfway. Is there anyone can complete this project. It will be a great help. Also happy to return the favor if  coder can leave his details e.g email or contact along with address.

 

My file is attached.  Below codes has to go in attached file along with email alert. Current code has email alert but as soon as the criteria met I kept getting email until as long as I dont close and delete the indicator from the MT4. Somehow require to code in a way that only get 1 alert once the criteria met.  Indicator name is Money Flow Index, I would like this with email alert.

 

 double ExtMFIBuffer[];

bool alreadyalerted=false;

string alertstr;

int init()

  {

   string sShortName;

//----

   SetIndexBuffer(0,ExtMFIBuffer);

//---- indicator line

   SetIndexStyle(0,DRAW_LINE);

//---- name for DataWindow and indicator subwindow label

   sShortName="MFI("+ExtMFIPeriod+")";

   IndicatorShortName(sShortName);

   SetIndexLabel(0,sShortName);

//---- first values aren't drawn

   SetIndexDrawBegin(0,ExtMFIPeriod);

//----

   return(0);

  }

int start()

  {

   int    i,j,nCountedBars;

   double dPositiveMF,dNegativeMF,dCurrentTP,dPreviousTP;

   

//---- insufficient data

   if(Bars<=ExtMFIPeriod) return(0);

//---- bars count that does not changed after last indicator launch.

   nCountedBars=IndicatorCounted();

//----

   i=Bars-ExtMFIPeriod-1;

   if(nCountedBars>ExtMFIPeriod) 

      i=Bars-nCountedBars-1;

   while(i>=0)

     {

      dPositiveMF=0.0;

      dNegativeMF=0.0;

      dCurrentTP=(High[i]+Low[i]+Close[i])/3;

      for(j=0; j<ExtMFIPeriod; j++)

        {

         dPreviousTP=(High[i+j+1]+Low[i+j+1]+Close[i+j+1])/3;

         if(dCurrentTP>dPreviousTP)

            dPositiveMF+=Volume[i+j]*dCurrentTP;

         else

           {

            if(dCurrentTP<dPreviousTP)

                dNegativeMF+=Volume[i+j]*dCurrentTP;

           }

          dCurrentTP=dPreviousTP;      

        }

      //----

      if(dNegativeMF!=0.0)      

         ExtMFIBuffer[i]=100-100/(1+dPositiveMF/dNegativeMF);

      else

         ExtMFIBuffer[i]=100;

      //----

      i--;

     }

   

//----


   if (ExtMFIBuffer[0] >= Overbought && alreadyalerted == false) {

      alertstr = StringConcatenate("MFI is High for ", Symbol(), " M", Period());

      if (alert == true)

         Alert(alertstr);

      if (emailAlert == true)

         SendMail("MT4 Chart Alert", alertstr);

      alreadyalerted = true;

   } 

   else if (ExtMFIBuffer[0] <= Oversold && alreadyalerted == false) {

      alertstr = StringConcatenate("MFI is Low for ", Symbol(), " M", Period());

      if (alert == true)

         Alert(alertstr);

      if (emailAlert == true)

         SendMail("MT4 Chart Alert", alertstr);

      alreadyalerted = true;

   }

   else if (alreadyalerted == true) {

     if (emailAlert == true) {

         alertstr = StringConcatenate("MFI is back to Middle for ", Symbol(), " M", Period());

        SendMail("MT4 Chart Alert", alertstr);

      }

      alreadyalerted = false;

   }

   return(0);

  }
