Hello Sierra Chart Support, I'm experiencing a persistent compilation issue while building a custom study from VectorAI.cpp using the Build Advanced Custom Studies interface. The .cpp file is located in the correct C:\SierraChart\ACS_Source directory, and #include "sierrachart.h" is present. However, I continue to receive the following error: java CopyEdit VectorAI.cpp:5:53: error: two or more data types in declaration of 'scsf_VectorAI' 5 | SCSFExport void scsf_VectorAI(SCStudyInterfaceRef sc) I’ve confirmed that sierrachart.h is present and that the header is properly included. Despite multiple adjustments, the same error persists during the build process. I’ve attached the current version of VectorAI.cpp for your review. Any guidance would be greatly appreciated. Thank you, Paul Strickland |

The code that you've uploaded does not have the error mentioned, it builds correctly. VectorAI.cpp:5:53: error: two or more data types in declaration of 'scsf_VectorAI' 5 | SCSFExport void scsf_VectorAI(SCStudyInterfaceRef sc) This is the cause of the error in whatever code you were trying to compile before (based on the error message above). Incorrect SCSFExport void scsf_VectorAI(SCStudyInterfaceRef sc) Correct SCSFExport scsf_VectorAI(SCStudyInterfaceRef sc) |

Hello Sierra Chart Support, We’ve spent the past two days troubleshooting a custom strategy that compiles, attaches correctly, and logs messages, but no trades are executing, and no trade markers are displayed. ✅ What We’ve Verified: Strategy compiles and loads without error Log messages confirm strategy is running and conditionally triggering Using [Sim] symbols (e.g., NQM25-CME[M]) Trade Activity Log is active and querying without errors Sim trading mode is enabled Time zone is synced correctly "Allow Simulated Resting Limit Order to Fill at Better Price" is enabled We've run it on aligned Renko and OHLC bar charts The sc.BuyEntry() function is called and logs confirm it Tried both actual conditions and a test strategy that simply buys every bar 📄 Test Code (Always Fires Market Orders) cpp Copy Edit #include "sierrachart.h" SCDLLName("VectorAI - Always Fire Test") SCSFExport void scsf_AlwaysBuy(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.GraphName = "ALWAYS BUY TEST"; sc.AutoLoop = 1; return; } s_SCPositionData position; sc.GetTradePosition(position); if (position.PositionQuantity == 0 && sc.GetBarHasClosedStatus() == BHCS_BAR_HAS_CLOSED) { s_SCNewOrder order; order.OrderType = SCT_ORDERTYPE_MARKET; order.OrderQuantity = 1; order.TextTag = "ALWAYS BUY"; int Result = sc.BuyEntry(order); sc.AddMessageToLog("ALWAYS BUY EXECUTED", 1); } } 🔧 Still Seeing: No trades in Trade Activity log No markers on chart No updates to Sim P/L Message Log confirms code runs, but no execution occurs 📷 Screenshots (Attached): Trade Simulation settings Message Log with trigger messages Trade Activity Log Chart with strategy attached (no markers shown) We’re happy to supply anything else needed to resolve this. We’ve ruled out most internal code issues — this feels like something environmental or session-related. Thank you for your help! Best regards, Paul & Ace (ChatGPT) |

Not Sierra Chart support, but I answered this and your other post. The other post has a reply with updated working code, I compliled and tested it. Custom Study Compiles but Not Recognized or Executed in Chart Replay Mode Something that you can add to your code that might help if you still have problems. Add this into the block where you make the buy entry attempt, it adds a message to the trade service log with the error reason. if (result < 0) sc.AddMessageToTradeServiceLog(sc.GetTradingErrorTextMessage(result), 0, 1); Date Time Of Last Edit: 2025-05-09 13:12:34

I have been through 6 different front end applications in the last 2 months searching for SierraChart. I am very pleased with the platform and your customer service is excellent. I am a fan! Thank you so much.
