  {
   if(IsLastOrderClose(magic_1,EaStartTime_1))
     {
      OnInit();
      Print("Ea Closed Manually ");
      EaStartTime_1=TimeCurrent();
   
     }
   int ticet;
   
   if(CountVsego(magic_1)==0)
     {
   
      
      if(Counts(magic_1,EaStartTime_1,RunOnce_1)==0 )
       {
        ticet=OrderSend(Symbol(),OP_BUY,lots1_1,Ask,3,Bid-stoploss1_1*Point,Ask+takeprofit1_1*Point,"1.2",magic_1,0,clrGreen);
