HELP NEEDED: Help with this function. The function should return true if the last two consecutive trades closed with a loss or with 0 profit.

//Returns true if last two closed trades ended up in a loss or 0(breakeven)
 bool LastTwoTradesLost(){
   double profitLossArray[];
   int totalCount =0;

      if(HistoryDealSelect(dealTicket)){
      if(HistoryDealGetString(dealTicket,DEAL_SYMBOL)==_Symbol){
      if(HistoryDealGetInteger(dealTicket,DEAL_ENTRY)==DEAL_ENTRY_OUT){
      
         totalCount=ArraySize(profitLossArray);
         ArrayResize(profitLossArray, totalCount+1);
         profitLossArray[totalCount]= HistoryDealGetDouble(dealTicket,DEAL_PROFIT);
         
         if(profitLossArray[0]<=0 && profitLossArray[1]<=0) //If last two trades ended in a loss

         return true; break;

The function should return true if the last two consecutive trades closed in a profit of 0 or at a loss. 

 
You applied ArraySize to an uninitiated array(profitLossArray). I am not sure what the output can be. If it is zero then profitLossArray[1] is out of range in first iteration of loop.
 
if(profitLossArray[totalCount-1]<=0 && profitLossArray[totalCount-2]<=0) //If last two trades ended in a loss

 
Also when iterating through deals to find the DEAL_ENTRY_IN, you don't wanna return false and break if the current deal is not what you're looking for.
it's easy to catch two consecutive loss trades using OnTrade() or OntradeTransaction() exactly when the loss happens. but if you have to dig the deals history, then your code needs a few corrections. one mentioned above, and one here.

Thanks for the help. I'm new in MQL5

Thank you! I will definitely try this out and give feedback here

Thanks for the help!

 

I did not test this:

 bool LastTwoTradesLost()
 {
   if(HistorySelect(0, TimeCurrent())==false) return false;   
   if(HistoryDealsTotal()<=1) return false;

   int totalCount =0;
   for(int i=HistoryDealsTotal()-1; i>=0; i--)
   {
      ulong dealTicket = HistoryDealGetTicket(i);
      if(dealTicket==0) continue;
      if(HistoryDealGetString(deal_Ticket, DEAL_SYMBOL)!=_Symbol) continue;
      if(HistoryDealGetInteger(dealTicket,DEAL_ENTRY)!=DEAL_ENTRY_OUT)continue;
      double PnL = HistoryDealGetDouble(dealTicket,DEAL_PROFIT);
      totalCount++;
      if(PnL>0) return false;
      if(totalCount==2) return true;
   }
   return false;
 }
  
// Returns true if the last two closed trades ended up in a loss or 0 (break-even)
bool LastTwoTradesLost() {
  double lastProfit = 0; // Variable to store the profit of the last closed trade
  double secondLastProfit = 0; // Variable to store the profit of the second last closed trade
  int count = 0; // Counter for the number of trades checked

  HistorySelect(0, TimeCurrent()); // Select the trade history till the current time

  // Loop through the trade history from the most recent trade
  for(int i = HistoryDealsTotal() - 1; i >= 0 && count < 2; i--) {
    ulong dealTicket = HistoryDealGetTicket(i);
    if(dealTicket > 0) {
      if(HistoryDealSelect(dealTicket)) {
        if(HistoryDealGetString(dealTicket, DEAL_SYMBOL) == _Symbol) {
          if(HistoryDealGetInteger(dealTicket, DEAL_ENTRY) == DEAL_ENTRY_OUT) {
            // For the first trade found, store its profit in lastProfit
            if(count == 0) {
              lastProfit = HistoryDealGetDouble(dealTicket, DEAL_PROFIT);
              count++;
            }
            // For the second trade found, store its profit in secondLastProfit
            else if(count == 1) {
              secondLastProfit = HistoryDealGetDouble(dealTicket, DEAL_PROFIT);
              count++;
            }
          }
        }
      }
    }
  }

  // Check if both trades ended in a loss or break-even
  if(count == 2 && lastProfit <= 0 && secondLastProfit <= 0) {
    return true;
  } else {
    return false;
  }
}
