I have a study that works fine, it displays bars that are greater in duration than the underlying [1T] chart. I can apply a study to the chart and it displays the study based on the bars I build as it should. I cannot apply a drawing to the chart with the mouse though. Should that be the case? The defaults are: if (sc.SetDefaults) { // Set the defaults sc.GraphName ="ACodeThingyToTestRxCode"; // This member indicates that this is a custom chart study. // This can only be set when SetDefaults is true. sc.IsCustomChart =1; sc.GraphRegion =0; sc.DrawZeros =0; sc.GraphDrawType =GDT_CANDLESTICK; sc.DisplayAsMainPriceGraph =1; sc.FreeDLL =1; sc.AutoLoop =0; sc.ValueFormat =VALUEFORMAT_INHERITED; sc.StandardChartHeader =1; // Subgraphs Open.Name ="Open"; Open.DrawStyle =DRAWSTYLE_LINE; High.Name ="High"; High.DrawStyle =DRAWSTYLE_LINE; Low.Name ="Low"; Low.DrawStyle =DRAWSTYLE_LINE; Last.Name ="Last"; Last.DrawStyle =DRAWSTYLE_LINE; return; } Edit: I did a little more checking, I can indeed draw a line, cannot draw a linear regression channel. Maybe if there is a problem it's just with that one tool... Date Time Of Last Edit: 2013-09-03 03:56:41

This code builds some 100 tick bars when applied to a 1T chart. I can draw a line on the produced bars but I cannot draw a linear regression channel. #include "sierrachart.h" /*==========================================================================*/ SCDLLName("Custom Study DLL") SCSFExport scsf_RxSubgraphBars(SCStudyInterfaceRef sc) { SCSubgraphRef Open =sc.Subgraph[0]; SCSubgraphRef High =sc.Subgraph[1]; SCSubgraphRef Low =sc.Subgraph[2]; SCSubgraphRef Last =sc.Subgraph[3]; if (sc.SetDefaults) { // Set the defaults sc.GraphName ="ForumCodeForBars"; // This member indicates that this is a custom chart study. // This can only be set when SetDefaults is true. sc.IsCustomChart =1; sc.DisplayAsMainPriceGraph =1; sc.GraphRegion =0; sc.GraphDrawType =GDT_CANDLESTICK; sc.ValueFormat =VALUEFORMAT_INHERITED; sc.DrawZeros =0; sc.FreeDLL =1; sc.AutoLoop =0; sc.StandardChartHeader =1; // Subgraphs Open.Name ="Open"; Open.DrawStyle =DRAWSTYLE_LINE; High.Name ="High"; High.DrawStyle =DRAWSTYLE_LINE; Low.Name ="Low"; Low.DrawStyle =DRAWSTYLE_LINE; Last.Name ="Last"; Last.DrawStyle =DRAWSTYLE_LINE; return; } for(int i =0; i<sc.ArraySize; i++) { if(i % 100 ==0) { sc.AddElements(1); sc.DateTimeOut[sc.OutArraySize -1] =sc.BaseDateTimeIn; High[sc.OutArraySize -1] =0; Low[sc.OutArraySize -1] =999999; Open[sc.OutArraySize -1] =sc.Open; if(sc.High >High[sc.OutArraySize -1]) { High[sc.OutArraySize -1] =sc.High; } if(sc.Low <Low[sc.OutArraySize -1]) { Low[sc.OutArraySize -1] =sc.Low; } } Last[sc.OutArraySize -1] =sc.Close; i++; } } |
