As long as you are displaying the values properly using the proper formatting function and formatting specification, persistent variables even without expressly resetting them in a study function, are at 0 when a study is applied to a chart or the Chartbook containing the chart which contains the study, is opened.
I thought the proper formatting might be the cause too so I checked countless times already on what I did. These are the codes that I am using to display values of my persist variables Trade_PosL and Trade_PosS: SCString Message7; Message7.Format("Buy PositionData Quantity: %d TradeS_OrderQuantity: %d Trade_PosL: %d", PositionData.PositionQuantity, fabs(TradeS.OrderQuantity), Trade_PosL); sc.AddMessageToLog(Message7, 0); SCString Message8; Message8.Format("Sell PositionData Quantity: %d TradeS_OrderQuantity: %d Trade_PosS: %d", PositionData.PositionQuantity, fabs(TradeS.OrderQuantity), Trade_PosS); sc.AddMessageToLog(Message8, 0); I know you don't provide Programming help and I am not expecting you to. I am just posting these codes here to show you what I did. I have used the same formatting to display other data and they are all displayed fine except these two persist variables. That's why it's so baffling and I am spending the time to create a support ticket for it. If you see something that's amiss, I would appreciate it if you can point it out. If not, you can just leave them to be. 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 is what I use in my codes to reset the persist variable: if (sc.Index == 0) { Trade_PosL = 0; Trade_PosS = 0; } Very simple codes and they worked fine all last year but for some reason not anymore for this year. I will try your suggestions to see if they work. Hopefully they do and I won't have to post here again. Date Time Of Last Edit: 2017-06-29 20:23:06
