It can be helpful if you add this code and write the result from the expert tab here.


 void UpdateTPbBUY()
{
for(int i=OrdersTotal()-1;i>= 0 ;i--)
{
   if(OrderSelect(i, SELECT_BY_POS, MODE_TRADES)==true)
       {
         if(OrderSymbol()==Symbol() && OrderType() == OP_BUY)
         {
          
          result abd=   OrderModify(OrderTicket(), OrderOpenPrice(),0,NetMeanOpeningPriceBuy(),0,0);
          Print(" TP :"+NetMeanOpeningPriceBuy()+" Error Codes "+GetLastError());
            
         } 
       }
}

Thank you sir for your response. On the Experts tab this error appear "2021.07.09 14:22:40.881 TestEa EURUSD,H1: Error in OrderModify. Error code=1"

i think i solved it i put this "double BEbuy=NetMeanOpeningPriceBuy();" above for loop. but ill test it again. thanks :)
