Hi, In ACSIL, is it possible to get the price values of the Valleys from the "Volume By Price" study? I've tried using Study/Price Overlays and Study Subgraph references and I've tried in ACSIL using sc.GetStudyArrayFromChartUsingID(), sc.ChartDrawingExists and GetUserDrawnChartDrawing(). I can't find the source for the Volume By Price study in the ACS sources folder. I think I probably need to write an ACSIL study to calculate these valley prices. Are there any examples I should look at? I see VAPContainer.h, is this the best place to start? I am very happy to pay for your support with this as it obviously goes beyond the scope of a normal support issue. Any assistance is greatly appreciated. Kind Regards, -Jason |

Hi, I did some more searches of your support site and found the following section. https://www.sierrachart.com/index.php?page=doc/VolumeByPrice.php#ProgrammaticallyAccessingVolumeAtPriceData I think this is what I was looking for and unfortunately I think it says I'm not able to get those values from the study itself. |

This led me to this section which I am now reading ACSIL Interface Members - Variables and Arrays: sc.VolumeAtPriceForBars |

In ACSIL, is it possible to get the price values of the Valleys from the "Volume By Price" study? This data is not programmatically accessible.

"This data is not programmatically accessible. You will need to calculate this using this data:" Can you provide the code |

I'm trying to get Valley values from a Volume Profile as well and trying to create a custom study using the function below from the studies2.cpp file. The below function negates the use of the sc.volumeatpriceforbars function doesn't it? sc.GetStudyPeakValleyLine example function ----------------------------------------------------------------------------*/ SCSFExport scsf_GetStudyPeakValleyLineExample(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { // Set the configuration and defaults sc.GraphName = "GetStudyPeakValleyLine Example"; sc.AutoLoop = 0; sc.Input[0].SetStudyID(1); sc.Input[0].Name = "Volume by Price Study"; return; } // Do data processing float PeakValleyLinePrice= 0; int PeakValleyType = 0; int StartIndex = 0; int PeakValleyExtensionChartColumnEndIndex = 0; // get the first Peak/Valley line from the last volume by price profile if (sc.GetStudyPeakValleyLine(sc.ChartNumber, sc.Input[0].GetStudyID(0), PeakValleyLinePrice, PeakValleyType, StartIndex, PeakValleyExtensionChartColumnEndIndex, -1, 0)) { // Peak/Valley line found int Test = 1; } |

It is using this function which has a particular purpose: sc.GetStudyPeakValleyLine If this is all that you need, this is all that you need. It is that simple.

Dean, in case you didn't notice - when implementing this you will likely want a loop to increment the "PeakValleyIndex" argument to sc.GetStudyPeakValleyLine to extract all of the valleys. For example: for (int i = 0; ; i++) {
if (sc.GetStudyPeakValleyLine(sc.ChartNumber, sc.Input[0].GetStudyID(0), PeakValleyLinePrice, PeakValleyType, StartIndex, PeakValleyExtensionChartColumnEndIndex, -1, i)) { if (PeakValleyType == PEAKVALLEYTYPE_VALLEY) { // Do whatever you want with PeakValleyLinePrice } } else break; } Date Time Of Last Edit: 2023-07-07 10:54:10
