Custom study. Code is very simple, really only 1 line, plots the % change. When I change the time frame, the study values disappear, and I have to "reload and recalculate" and they come back. Why is this? SCSFExport scsf_PercentChangeSinceClose(SCStudyInterfaceRef sc)
{ if(sc.SetDefaults) { sc.GraphName="Percent Change Since Close"; sc.StudyDescription="Calculates the percentage a stock is up or down, based on the prior close."; sc.AutoLoop = 1; sc.GraphRegion = 0; sc.FreeDLL = 1; sc.ValueFormat = 2; sc.Subgraph[0].Name = "Percent Change"; sc.Subgraph[0].PrimaryColor = RGB(100,100,100); // Gray sc.Subgraph[0].DrawStyle = DRAWSTYLE_LINE; return; } sc.Subgraph[0][sc.Index] = ((sc.Close[sc.Index] / sc.PreviousClose) - 1) * 100; } Date Time Of Last Edit: 2015-01-29 18:30:25

This is because this value sc.PreviousClose is 0 upon a reload of the chart. You really need to use this function: http://www.sierrachart.com/index.php?page=doc/doc_ACSIL_Members_Functions.html#scGetOHLCForDate Sierra Chart Support - Engineering Level Your definitive source for support.

That function is no good because it uses the intraday data which is not the correct closing/settlement value. But I will try to use an external historical chart which should have the closing value of the bar as the settlement -- thank you
