I am trying to build a custom study that will send post data to a python script when a trade I entered or exited on Sierra chart, and I am getting error codes when I try to build it. These are the error codes: C:\SierraChart\ACS_Source\chickwasodpasda.cpp(34): error C3680: cannot concatenate user-defined string literals with mismatched literal suffix identifiers C:\SierraChart\ACS_Source\chickwasodpasda.cpp(34): note: Concatenating suffix 'type' with suffix 'entry' C:\SierraChart\ACS_Source\chickwasodpasda.cpp(34): error C3680: cannot concatenate user-defined string literals with mismatched literal suffix identifiers C:\SierraChart\ACS_Source\chickwasodpasda.cpp(34): note: Concatenating suffix 'type' with suffix 'symbol' C:\SierraChart\ACS_Source\chickwasodpasda.cpp(34): error C3680: cannot concatenate user-defined string literals with mismatched literal suffix identifiers C:\SierraChart\ACS_Source\chickwasodpasda.cpp(34): note: Concatenating suffix 'type' with suffix 'price' C:\SierraChart\ACS_Source\chickwasodpasda.cpp(34): error C3688: invalid literal suffix 'type'; literal operator or literal operator template 'operator ""type' not found C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): error C3680: cannot concatenate user-defined string literals with mismatched literal suffix identifiers C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): note: Concatenating suffix 'type' with suffix 'exit' C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): error C3680: cannot concatenate user-defined string literals with mismatched literal suffix identifiers C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): note: Concatenating suffix 'type' with suffix 'symbol' C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): error C3680: cannot concatenate user-defined string literals with mismatched literal suffix identifiers C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): note: Concatenating suffix 'type' with suffix 'entry_price' C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): error C3680: cannot concatenate user-defined string literals with mismatched literal suffix identifiers C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): note: Concatenating suffix 'type' with suffix 'exit_price' C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): error C3680: cannot concatenate user-defined string literals with mismatched literal suffix identifiers C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): note: Concatenating suffix 'type' with suffix 'points' C:\SierraChart\ACS_Source\chickwasodpasda.cpp(51): error C3688: invalid literal suffix 'type'; literal operator or literal operator template 'operator ""type' not found This is the code in the file I selected: #include "sierrachart.h" #include "scstructures.h" SCDLLName("HTTP POST Example") // Global variables to track trade entry and exit float tradeEntryPrice = 0.0f; // Use 'f' for float literals bool inTrade = false; // Custom study function SCSFExport scsf_HTTPPOSTExample(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.GraphName = "HTTP POST Example"; sc.AutoLoop = 1; return; } // Define the URL of your Flask application endpoint SCString URL = "http://127.0.0.1:5000/trade"; // Replace with your server's IP and port // Fetch the symbol SCString symbol = sc.GetChartSymbol(sc.ChartNumber); // Get trade position data s_SCPositionData PositionData; if (!sc.GetTradePosition(PositionData)) { // Handle error if unable to get position data sc.AddMessageToLog("Failed to get trade position data", 1); return; } // Check if there is an open position if (PositionData.PositionQuantity != 0 && !inTrade) { tradeEntryPrice = static_cast<float>(PositionData.AveragePrice); // Explicitly cast to float inTrade = true; // Construct the POST data for entry SCString POSTData = "{ "type": "entry", "symbol": "" + symbol + "", "price": "" + std::to_string(tradeEntryPrice) + "" }"; // Headers (if needed) SCString Headers = "Content-Type: application/json"; // Make the HTTP POST request for entry sc.MakeHTTPRequest(POSTData + Headers); // Log the result SCString logMessage = "HTTP POST Entry result: "; sc.AddMessageToLog(logMessage, 0); } // Check if the position is closed if (PositionData.PositionQuantity == 0 && inTrade) { float tradeExitPrice = static_cast<float>(sc.Close[sc.Index]); // Example: Exit using the current close price inTrade = false; // Calculate profit or loss in points float profitLossPoints = tradeExitPrice - tradeEntryPrice; // Construct the POST data for exit SCString POSTData = "{ "type": "exit", "symbol": "" + symbol + "", "entry_price": "" + std::to_string(tradeEntryPrice) + "", "exit_price": "" + std::to_string(tradeExitPrice) + "", "points": "" + std::to_string(profitLossPoints) + "" }"; // Headers (if needed) SCString Headers = "Content-Type: application/json"; // Make the HTTP POST request for exit sc.MakeHTTPRequest(POSTData + Headers); // Log the result SCString logMessage = "HTTP POST Exit result: "; sc.AddMessageToLog(logMessage, 0); } } Would love some help with what I need to change in the code to fix this, thanks! |
