Function which allow 1 trade per candle not at beginning of candle only

[Youg Chee]

How can I make a function that only allow 1 trade or open position per candle not only at the beginning of the candle but until new candle forms. The newbar function only allows at beginning of new candle only 

[Navdeep Singh]

Capture the count of opened trade in a variable and use it as an additional condition to avoid entering new trade. Reset it to zero on new bar. This may help

You code it exactly the same. When you open a new trade, remember the current candle's time. If they are the same, don't open a new one.

Code:

Even if this is your approach the function should return proper value

return(hastraded);

and also select the position by index before you start working with them

bool Tradeallowed(){

      bool hastraded = false;
      
    for(int a =PositionsTotal()-1;a>=0;a--){
         
         string symbol1 = PositionGetSymbol(a);  
         
         if(Symbol() == symbol1){
                  
            ulong pticket1 = PositionGetTicket(a);
            double csl1 = PositionGetDouble(POSITION_SL);
            int posT = PositionGetInteger(POSITION_TYPE);
          
               if(posT == POSITION_TYPE_BUY){
            
                       hastraded = true;
