Hi friends, i want to enter the position and for example when i buy, trailing stop must to placed 300 points below and must follow the current price.
Where did i went wrong?


#include <Trade\Trade.mqh>

CTrade trade;

int OnInit(void){

   return(INIT_SUCCEEDED);

}



void OnTick(void)

  {

      myOnTick();

  }



void myOnTick()

{

 

 double Ask=NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_ASK),_Digits);  //satış fiyatını sorguladık

 double Bid=NormalizeDouble(SymbolInfoDouble(_Symbol,SYMBOL_BID),_Digits);  //alış fiyatını sorguladık

 

  //******************************************************************mum tanımlama****************************

   

  double current_close=iClose(_Symbol,PERIOD_CURRENT,0);

  double current_low = iLow(_Symbol,PERIOD_CURRENT,0);

  double current_high = iHigh(_Symbol,PERIOD_CURRENT,0);

  

  

  //******************************************************************some indicator definitons are here *************************

   double ...[];

   int ...Definition = iCustom(_Symbol,_Period,"...");  

   ArraySetAsSeries(...,true);

   CopyBuffer(...Definition,0,0,5,...);

   if (PositionsTotal() == 0){

      if (current_close>...[1])

        trade.Buy(0.01,NULL,Ask,(Ask-1000*_Point),(Ask + 500 * _Point),NULL); 

         

      if ( current_close<...[1])

         trade.Sell(0.01,NULL,Ask,(Ask-1000*_Point),(Ask + 500 * _Point),NULL); 

   } else {

   

  

 

      CheckTrailingStop(Ask);

   

   }

}





void CheckTrailingStop (double Ask)

  {

   double SL = NormalizeDouble(Ask - 300 * _Point, _Digits);   

   for(int i=PositionsTotal()-1; i>=0;i--)                     

      {

       string symbol=PositionGetSymbol(i);                       

         if(_Symbol==symbol)                                          

         {

           ulong PositionTicket = PositionGetInteger(POSITION_TICKET);                 

           double CurrentStopLoss=PositionGetDouble(POSITION_SL);                    

           if (CurrentStopLoss<SL)                                                                         

             {  trade.PositionModify(PositionTicket,(CurrentStopLoss + 300*_Point),0);  

             }

         }            //end symbol for loop

      }              //end trailin stop bracket
