This really only can be done by Sierra Chart itself, when building chart bars and the arrays of this data are already available: ACSIL Interface Members - Variables and Arrays: sc.BaseDataIn[][] / sc.BaseData[][] sc.BaseData[SC_ASKBID_DIFF_HIGH]: The array containing the maximum difference between the Ask volume and the Bid volume for the bar at the specified Index. This is calculated at every tick during the creation of the bar.
For the data in this array to be most accurate, the Intraday Data Storage Time Unit setting in Global Settings >> Data/Trade Service Settings needs to be 1 Tick. The data in this array will not be available for historical data that does not have Ask Volume and Bid Volume. For the chart to maintain the data in this array, you need to set sc.MaintainAdditionalChartDataArrays to TRUE in the sc.SetDefaults code block in your study function. sc.BaseData[SC_ASKBID_DIFF_LOW]: The array containing the minimum difference between the Ask volume and the Bid volume for the bar at the specified Index. This is calculated at every tick during the creation of the bar. For the data in this array to be most accurate, the Intraday Data Storage Time Unit setting in Global Settings >> Data/Trade Service Settings needs to be 1 Tick. The data in this array will not be available for historical data that does not have Ask volume and Bid Volume. For the chart to maintain the data in this array, you need to set sc.MaintainAdditionalChartDataArrays to TRUE in the sc.SetDefaults code block in your study function.
