I want to modify the stock 'Highest High Lowest Low over N bars' study to include the "use current bar value" input (see below)

I have been able to hack this piece of code into some of the easier studies (SCStudyGraphRef sg.) but not the more complex (SCStudyInterfaceRef sc.)

 

Code

sg.Input[5].Name="Use current bar value?"; sg.Input[5].SetYesNo(0); // No

Here is the code for HH LL over N bars from STUDIES7.cpp

Thanks in advance for any help

 

Code

/*==========================================================================*/ SCSFExport scsf_HighestHighLowestLowOverNBars(SCStudyInterfaceRef sc) { SCSubgraphRef HighestHigh = sc.Subgraph[0]; SCSubgraphRef LowestLow = sc.Subgraph[1]; SCInputRef Length = sc.Input[3]; SCInputRef InputDataHigh = sc.Input[5]; SCInputRef InputDataLow = sc.Input[6]; if (sc.SetDefaults) { sc.GraphName = "Highest High / Lowest Low Over N Bars"; sc.GraphRegion = 0; sc.AutoLoop = 1; HighestHigh.Name= "Highest High"; HighestHigh.DrawStyle = DRAWSTYLE_LINE; HighestHigh.PrimaryColor = RGB(0,255,0); HighestHigh.DrawZeros = true; LowestLow.Name = "Lowest Low"; LowestLow.DrawStyle = DRAWSTYLE_LINE; LowestLow.PrimaryColor = RGB(255,0,255); LowestLow.DrawZeros = true; Length.Name = "Length"; Length.SetInt(5); Length.SetIntLimits(1, MAX_STUDY_LENGTH); InputDataHigh.Name = "Input Data High"; InputDataHigh.SetInputDataIndex(SC_HIGH); InputDataLow.Name = "Input Data Low"; InputDataLow.SetInputDataIndex(SC_LOW); return; } sc.DataStartIndex = Length.GetInt() - 1; if (sc.Index < sc.DataStartIndex) return; double Lowest = FLT_MAX; double Highest = -FLT_MAX; for(int BarIndex = sc.Index - (Length.GetInt() - 1); BarIndex <= sc.Index; BarIndex++) { if(Highest < sc.BaseDataIn[InputDataHigh.GetInputDataIndex()][BarIndex]) Highest = sc.BaseDataIn[InputDataHigh.GetInputDataIndex()][BarIndex]; if(Lowest > sc.BaseDataIn[InputDataLow.GetInputDataIndex()][BarIndex]) Lowest = sc.BaseDataIn[InputDataLow.GetInputDataIndex()][BarIndex]; } HighestHigh[sc.Index] = (float)Highest; LowestLow[sc.Index] = (float)Lowest; }

I have created a version that I think does what you want.

Hope this helps.

Thanks!

Will give it a go.
