Post From: Persist Variables

Also I am using persistent variables via the following manner: int& variable_name = sc.PersistVars->Integers[0]; and then variable_name = 2; It worked all fine last year. According to your documentation, https://www.sierrachart.com/index.php?page=doc/ACSIL_Members_Variables_And_Arrays.html#scPersistVars: Available Persistent Variables sc.PersistVars->i1 through sc.PersistVars->i16. Integer data type. sc.PersistVars->f1 through sc.PersistVars->f16. Single precision floating-point data type. sc.PersistVars->d1 through sc.PersistVars->d24. Double precision floating-point data type. sc.PersistVars->scdt1 through sc.PersistVars->scdt8. SCDateTime variable type. sc.PersistVars->Integers[64]. Integer data type. sc.PersistVars->Doubles[64]. Double precision floating-point data type. Example // You can use references to give the persistent variables // more descriptive names that you can use. // MyCounter is a reference to sc.PersistVars->Integers[0] int& MyCounter = sc.PersistVars->Integers[0]; // MyAverage is a reference to sc.PersistVars->Doubles[2] double& MyAverage = sc.PersistVars->Doubles[2]; // We are using the reference we made above. // This is the same as: sc.PersistVars->Integers[0] += 1; MyCounter += 1; // We are using the reference we made above. // This is the same as: sc.PersistVars->Doubles[2] = (10.0f+24.0f)/2.0f; MyAverage = (10.0f+24.0f)/2.0f; // We are using the reference we made above. MyAverage = (sc.Subgraph[2][sc.Index]+24.0f)/2.0f; Resetting Persistent Variables Example if (sc.Index == 0) { // When there is a full recalculation of the study, // reset the persistent variables we are using sc.PersistVars->Integers[0] = 0; sc.PersistVars->Integers[1] = 0; sc.PersistVars->Integers[2] = 0; sc.PersistVars->Integers[3] = 0; } this format is available for backward compatibility so everything compiled but when I try to change values to the persistent variables, the new values did not get set and the default value for persistent variables are supposed to be 0.00 but it's a ridiculously huge number such as these: Chart: Replay 1.0X: XXXX 60 Min #2 | Study: Custom DLL Study | Buy PositionData Quantity: 0 TradeS_OrderQuantity: 0 Trade_PosL: 1086121984 | 2017-06-27 05:18:06 Chart: Replay 1.0X: XXXX 60 Min #2 | Study: Custom DLL Study | Sell PositionData Quantity: 0 TradeS_OrderQuantity: 0 Trade_PosS: 1086121984 | 2017-06-27 05:18:06 Chart: Replay 1.0X: XXXX 60 Min #2 | Study: Custom DLL Study | | 2017-06-27 05:18:06 My two persistent variables are Trade_PosL and Trade_PosS and they are NEVER set to 0 to begin with. They always stay as 1086121984 throughout the running of the whole program and because of this problem, my program is not sending any trades. Please investigate and advise. |
