If you are the developer of a custom study, never change the elements of this array:
Nobody changes it. The statement above is incorrect. This error occurs after updating the SC when the user does not recompile the library (or when use a third-party library that is not recompiled to a newer version). This is related to the change in SCDateTime functionality described in the 2195 notes. https://www.sierrachart.com/index.php?page=doc/Whats_New.php#SCVer2195 Try this code below recompiled in version 2192 and open Sierrachart 2204. You will get a result with zeros on the axis. (attached file) SCSFExport scsf_example(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.GraphName = "Example"; sc.GraphRegion = 1; sc.AutoLoop = 0; return; } for (int BarIndex = sc.UpdateStartIndex; BarIndex < sc.ArraySize; BarIndex++) { if (BarIndex > 0) { SCDateTime PreviousTradingDayStartDateTimeOfBar = sc.GetTradingDayStartDateTimeOfBar(sc.BaseDateTimeIn[BarIndex - 1]); SCDateTime TradingDayStartDateTimeOfBar = sc.GetTradingDayStartDateTimeOfBar(sc.BaseDateTimeIn[BarIndex]); } } } This is not to say that you are doing something wrong. You warned in advance that libraries should be recompiled. Just my opinion: If the content of a feature changes significantly in this way, it should be a "forced update," not just a "recommended update." Date Time Of Last Edit: 2020-12-04 23:11:08
