Thanks for the fast reply. Just to give some context: I have read every letter of the documentation. I think I grasp the core of STL_vectors, classes, ect. I have implemented the examples from the sierra website including some code they refer to in their ASC_source folder. and again, the code works fine it does what it needs to, to the extent of creating the vector, setting everything to NULL, initiating a persistentpointer, etc. It just loses the values wehn a new bar comes to the chart. I could refer to a previous index [sc.Index-1] and reuse the vector at that index, however, I don't know if that is possible at all. The codes I tried give an error. see code bellow. I cant seem to get past this issue. So if you have any concrete code tips, I would be more than gratefull. //initiating the vector std::vector<double>* InbLines; if(sc.LastCallToFunction) { if(InbLines != NULL) { delete InbLines; sc.SetPersistentPointer(1, NULL); } return; } if (InbLines == NULL) { InbLines = new std::vector<double>; if(InbLines != NULL) sc.SetPersistentPointer(1, InbLines); else { sc.AddMessageToLog("Memory allocation error.", 1); return; } } // doing some calculations, bla bla.. // lines 1 to 5 found in previous section adding them to the vector if ( LineONE != 0) { InbLines->push_back(LineONE); CURRENT_keys++; } if ( LineTWO != 0) { InbLines->push_back(LineTWO); CURRENT_keys++; } if ( LineTHREE != 0) { InbLines->push_back(LineTHREE); CURRENT_keys++; } if ( LineFOUR != 0) { InbLines->push_back(LineFOUR); CURRENT_keys++; } if ( LineFIVE != 0) { InbLines->push_back(LineFIVE); CURRENT_keys++; } } // counting the number of elements and showing it at the bottom each bar via a Subgraph. This way I can count the amount of doubles inside the vector at a specific bar NumbT[sc.Index] = InbLines->size(); NumbOnLow[sc.Index] = NumbT[sc.Index]; Date Time Of Last Edit: 2024-12-24 12:45:25
