Hi Team,

Thank you for the clarification. Then the problem seems to be that it still sometimes misses sending the info/showing the print statement. Is there anything I should optimize in the code?

Right now, the way I'm testing this is by almost spamming the buy/sell market button but this is to make sure that ALL the orders are sent successfully to the server. I verified the server logs also and it has processed everything it gets from SierraChart, but SierraChart sometimes does not send ALL the orders - especially if the order execution on the platform is done very fast.


  if (CurrentOrderFillEntrySize != PriorOrderFillEntrySize){
    PriorOrderFillEntrySize = CurrentOrderFillEntrySize;
    if (CurrentOrderFillEntrySize > 0){
      s_SCOrderFillData OrderFillData;
      sc.GetOrderFillEntry(CurrentOrderFillEntrySize - 1, OrderFillData);
      SCString OrderFillMessage;
      s_SCPositionData SCPositionData;
      int got_position = sc.GetTradePosition(SCPositionData);

      OrderFillMessage.Format("...",...);
      SCString LogMessage;
      LogMessage.Format("[%s] %s [x %u] @ %f [Side: %d] [fill id: %s]",
                sc.DateTimeToString(OrderFillData.FillDateTime, FLAG_DT_COMPLETE_DATETIME_MS).GetChars(),
                OrderFillData.Symbol.GetChars(),
                static_cast<uint32_t>(OrderFillData.Quantity),
                OrderFillData.FillPrice,
                OrderFillData.BuySell,
                OrderFillData.FillExecutionServiceID.GetChars()
      );
      sc.AddMessageToLog(LogMessage, 0);
      sc.AddMessageToLog("Preparing to send message", 0);
      
      if (RequestState == REQUEST_NOT_SENT){
        if (!sc.MakeHTTPPOSTRequest(PostURL, OrderFillMessage, &HTTPHeader, NumberOfHeaders)){
          sc.AddMessageToLog("Error making HTTP request.", 0);
          RequestState = REQUEST_NOT_SENT;
        }else{
          RequestState = REQUEST_SENT;
          sc.AddMessageToLog("HTTP Request Sent Successfully!", 0);
        }
      }
      
      if (RequestState == REQUEST_SENT && sc.HTTPResponse != ""){
        RequestState = REQUEST_RECEIVED;
        sc.AddMessageToLog(sc.HTTPResponse, 0);
      }else if (RequestState == REQUEST_SENT && sc.HTTPResponse == ""){
        sc.AddMessageToLog("HTTP req NOT complete yet", 0);
      }
      sc.AddMessageToLog(sc.HTTPResponse, 0);
    }
  }

The above is the full code including the print to message log code + send to server code. If it's asynchronous, then I should be able to see ALL messages being sent even if the server is slow right? But that is not the case here. Is this a problem of the code I've written above being inefficient/slow?


Edit: I've removed almost all the print code and only kept `sc.MakeHTTPPOSTRequest(PostURL, OrderFillMessage, &HTTPHeader, NumberOfHeaders)` - the result is still missing ~10 orders.

I'm simply comparing the no. of "Making HTTTP POST request" to the no. of fills in the activity log. Most recent comparison: 88 vs 98.
