Mt5 event process

[Hiệp Lê]

Hello, I have written a code, it's something like this:

void OnTick()
  { 
   if(isNewBar())
      {
      buy_signal=false;
      sell_signal=false;
      
      if(...)
         {
         buy_signal=true;
         }
      else if(...)
         {
         sell_signal=true;
         }
      }
  }
//+------------------------------------------------------------------+
void OnTrade()
  {
  ...
    
  if (buy_signal==true)
   {
   trade_execution.Buy(trade_volume,_Symbol,trade_price,stop_loss,take_profit);
   buy_signal=false;
   }
  else if (sell_signal==true)
   {
   trade_execution.Sell(trade_volume,_Symbol,trade_price,stop_loss,take_profit);
   sell_signal=false;
   }
  }

I have 2 questions about the process:

1/ Assump that I don't to turn the buy signal off after the buy/sell execution, will it keep buying/selling each time the price touch the price I set for buy/sell?

2/ Assump that a position is open, and then it's closed by stop loss or take profit, and then the buy/sell signal turn true again, will it buy/sell again?

Thanks for any help.

You do not trade in OnTrade. You trade in OnTick. OnTrade tell you something happened (new pending, pending/market opened, position closed, etc.)

Thanks a lot, it would be easier for me to understand the process if I trade OnTick.

We CANNOT trade in OnTrade OR we SHOULD NOT trade in OnTrade?
