Post From: Set Volume-by-Price "Ticks per volume bar" by setting exact number of VbP bars on chart?

1, automatically adjusting the VbP according to changes in volatility
That is incorrect, VbP's Ticks Per Volume Bar should always set as 1 tick, regardless of volatility.2, Is there a way to automatically set the "ticks per volume bar" just by giving a number of VbP bars I want to see on the chart
no, because each session's range is different.3, Ideally, there could also be +/- buttons on the Control Bar to adjust that number (more or less VbP bar density)
yes, you can set "Tick Per Volume" by a ACSIL fuction called "sc.SetChartStudyInputInt()"Sample code: #include "sierrachart.h" SCDLLName("VbP_Tick") SCSFExport scsf_VbP_Tick(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.GraphName = "Change VbP Tick Number"; sc.GraphRegion = 0; sc.UpdateAlways = 1; sc.ReceiveCharacterEvents = 1; sc.AutoLoop = 1; return; } int VbP_ID {1}; int Tick_Number {1}; // change Tick_Number based on keyboard input, + to increase, - to decrease if (sc.CharacterEventCode==43) { Tick_Number = min(50, Tick_Number+1); sc.SetChartStudyInputInt(sc.ChartNumber, VbP_ID, 31, Tick_Number); } if (sc.CharacterEventCode==45) { Tick_Number = max(1, Tick_Number-1); sc.SetChartStudyInputInt(sc.ChartNumber, VbP_ID, 31, Tick_Number); } } Date Time Of Last Edit: 2023-08-05 10:42:36
