Hi SC team, I wrote a study using ASCIL that displays a colored bar based on a calculated number (capture1.jpg) In another dll I would like to get the calcultated number calling this DLL. I went through ACSIL Programming Concepts: Making Function Calls to External DLLs but I can't figure out on how to process. My dll file is gfx_Studies_64.dll In my trading system study, I could add the following line and compile // -------------------------------------------------------------------------- HINSTANCE hInstLibrary = LoadLibrary("gfx_Studies_64.dll"); // -------------------------------------------------------------------------- in gfx_Studies_64.dll I calculation is done in a specific study SCSFExport scsf_EasyTrend(SCStudyInterfaceRef sc) { What code do I need to add in my trading system study in order to call scsf_EasyTrend and retreive the computed value ? Also, is there any code to add to gfx_Studies_64.dll in order to allow external calls ? Thks for your help. B. gfx

If EasyTrend has a subgraph that outputs the number you want then you can use sc.GetStudyArrayUsingID.

EasyTrend is not displayed on the chart. It doesn't have to be displayed, it could be hidden. If you are saying that EasyTrend is providing data to gfx_Studied.dll, does it use a subgraph?

Hi, thks Sorry for the confusion. In fact, even hidden, it won't be attached to the chart. What I meant is to be able into my trading system to write such a line .... int myTrend = Call scsf_EasyTrend(sc) and get as a result in myTrend the value calculated in the study gfx_Studies_64.dll I hope it clarifies.
