[abricot911]

hello,

can you help me please :)

string CheckFilter(){
   string filter="";
   double myPriceArray[];
   int VolumesDefinition = iVolume(_Symbol,_Period,VOLUME_TICK); 
   ArraySetAsSeries(myPriceArray,true);
   CopyBuffer(VolumesDefinition,0,0,3,myPriceArray);
   float CurrentVolumeValue=(myPriceArray[0]);
   float LastVolumesValue = (myPriceArray[1]);
   
   if(CurrentVolumeValue>LastVolumesValue){
      filter="positive";
   }
   if(CurrentVolumeValue<LastVolumesValue){
      filter="negative";
   }
   
   return filter;
}


void OnTick(){
   string filter = CheckFilter();
   Alert(filter);

put in an else statement int error=GetLastError() then Print(error) to see why.

1. This is the MT4 forum.
   1. The function does not return a handle.
      

   2. Your code	Documentation
      int VolumesDefinition = iVolume(             _Symbol,             _Period,             VOLUME_TICK );	long  iVolume(    string           symbol,          // symbol    int              timeframe,       // timeframe    int              shift            // shift    );

      Not a proper shift.

   3. There is no copyBuffer, in the language.
   4. There is no VOLUME_TICK, in the language.

2. In MT5, the function is: iVolumes, with a "s."

MT5 forum is down sorry

That doesn't make sense. mql4/MT4 forum is a sub-forum of mql5 on the same domain. So if "MT5 forum is down, MT4 is down too".
