Hello, I declared global variable in StudyA: SCDLLName("StudyA") int GlobalLastSeparatorIndex; Then I want to get the value of this global variable in StudyB: int Test = GlobalLastSeparatorIndex; Build Output gives this message: error: GlobalLastSeparatorIndex was not declared in this scope How to make StudyB aware of the Global variable? thank you |

It really is best to use persistent variables for this: https://www.sierrachart.com/index.php?page=doc/doc_ACSIL_Members_Functions.html#scGetPersistentInt And then use this function to get the persistent variable from another study: https://www.sierrachart.com/index.php?page=doc/doc_ACSIL_Members_Functions.html#scGetStudyPersistentIntFromChart Sierra Chart Support - Engineering Level Your definitive source for support.

I used your recommendation and it helped me to move forward with my task. thank you. However, I still have a question, I think it somehow relates to the first question. I need to do some processing during recalculation (and then I want to display the result on bars being recalculated): StudyB is processing an input ( sc.Index value) from persistent variable in StudyA . The issue is, that the value transferred to Study B is always the same on the recalculated bars, but it should be different value for each bar ( the sc.Index ). Seems that all the recalculated bars get as an input the same value, the sc.Index of the last recalculated bar. STUDY A int& TestIndex = sc.GetPersistentInt(5); sc.SetPersistentInt(5, sc.Index); STUDY B if ( sc.IsFullRecalculation ) { int AAA = sc.GetStudyPersistentIntFromChart(sc.ChartNumber,1,5); } |
