I have built a study that needs to pull/have access to live volume-at-price data so that it can derive values such as Ask-Bid volume at Price, Delta-At-Price, Delta High, Delta Low, Total volume at price, etc. Can you tell me which study is best for this purpose? Numbers bar? Numbers Bar calculated values? The study may be able to internally compute things like "Max/Min Delta" so it may only need the raw data, but for other values, like "Finish Delta%", it may need the value already computed (candle bar totals will not be enough, needs to be "at-price" level data) . Thx!

Assuming you are creating an ACSIL custom study: Advanced Custom Study Interface and Language (ACSIL) You then need to use the Volume at Price data: ACSIL Interface Members - Variables and Arrays: sc.VolumeAtPriceForBars Sierra Chart Support - Engineering Level Your definitive source for support.

Thank you. This should work for most values. However, since Finish Delta and Finish Delta% require intra-bar recency data (ie. If the Ask Volume Bid Volume Difference High was more recently increased as compared to the Ask Volume Bid Volume Difference Low being more recently decreased, then Finish AskVol BidVol Diff equals the Ask Volume Bid Volume Difference for the bar minus the Ask Volume Bid Volume Difference High for the bar.) which is not provided by sc.VolumeAtPriceForBars, how do you suggest the study access these values?

Is this what you are looking for: sc.BaseData[SC_ASK_BID_VOL_DIFF_MOST_RECENT_CHANGE]: This array contains a value indicating whether the SC_ASKBID_DIFF_HIGH or the SC_ASKBID_DIFF_LOW array was most recently changed.
It will be set to 1 if the SC_ASKBID_DIFF_HIGH array at the corresponding element was most recently changed. It will be set to -1 if the SC_ASKBID_DIFF_LOW array at the corresponding element was most recently changed. When using this array in a study function, it is necessary to set sc.MaintainAdditionalChartDataArrays to 1 in the sc.SetDefaults code block.
