Hi, I am writing up some code that marks bar patterns. I wrote a test project (shown below), just to illustrate that I can mark red bars. However, this logic is run every single tick I think, which is a waste of CPU time. In easylanguage they have a condition where u can check if its the closing tick of the bar, so that you only need to run the logic one time per bar, I don't see how to do this in the Sierra Chart code... Also I find that I must put "Marker[cur]= 0;" rather than "Marker[cur-1]= 0;" to make it work, which doesn't seem logical to me. This statement is on the 3rd line or so at the bottom of the example. My code example is here below: SCSFExport scsf_Calculator(SCStudyGraphRef sc) { // Section 1 - Set the configuration variables SCSubgraphRef Marker = sc.Subgraph[0]; // This section is only run once. Refer to documentation for further details. if (sc.SetDefaults) { // Set the configuration and defaults sc.GraphName = "Calculator"; sc.StudyDescription = "Insert study description here."; sc.AutoLoop = 1; // true sc.FreeDLL = 1; sc.GraphRegion = 0; Marker.Name = "Dot Marker"; Marker.PrimaryColor = RGB(102,255,102); // Optionally, you may predefine your graph's colors Marker.DrawStyle= DRAWSTYLE_POINT; Marker.PrimaryColor = RGB(255,255,255); Marker.LineWidth = 3; Marker.DrawZeros = false; return; } // Section 2 - Data processing int cur = sc.Index; Marker[cur]= (sc.BaseDataIn[SC_LOW][cur-1] - 2sc.TickSize); //if(sc.GetBarHasClosedStatus(sc.Index-1) == BHCS_BAR_HAS_CLOSED) // { if( sc.Open[cur-1] > sc.Close[cur-1]) //if (Range > 0.0f) { Marker[cur-1]= (sc.BaseDataIn[SC_LOW][cur-1] - 2sc.TickSize); } { Marker[cur]= 0; } }

I cleaned up the code to make it more logical, but now it wont make points at all on the chart, anyway, here is the cleaned up non-working at all version.. SCSFExport scsf_Calculator(SCStudyGraphRef sc) { // Section 1 - Set the configuration variables SCSubgraphRef Marker = sc.Subgraph[0]; // This section is only run once. Refer to documentation for further details. if (sc.SetDefaults) { // Set the configuration and defaults sc.GraphName = "Calculator"; sc.StudyDescription = "Insert study description here."; sc.AutoLoop = 1; // true sc.FreeDLL = 1; sc.GraphRegion = 0; Marker.Name = "Dot Marker"; Marker.DrawStyle= DRAWSTYLE_POINT; Marker.PrimaryColor = RGB(255,255,255); Marker.LineWidth = 3; Marker.DrawZeros = false; return; } // Section 2 - Data processing int cur = sc.Index; //if(sc.GetBarHasClosedStatus(sc.Index-1) == BHCS_BAR_HAS_CLOSED) if( sc.Open[cur-1] > sc.Close[cur-1]) { Marker[cur-1]= (sc.Low[cur-1] - 2*sc.TickSize); } { Marker[cur-1]= 0; } }

In easylanguage they have a condition where u can check if its the closing tick of the bar, so that you only need to run the logic one time per bar, I don't see how to do this in the Sierra Chart code... Refer to this function: https://www.sierrachart.com/index.php?page=doc/doc_ACSIL_Members_Functions.html#scGetBarHasClosedStatus However, what the function does is very simple. It simply indicates the bar has closed for every bar other than the last bar in the chart.
