Value of study (indicator) inside my custom code

[TradingFrank]

does anyone know how I can use the values of a given indicator, in my case, I like to use volume profile and volume imprint and cumulative delta inside my own calculator?
The SDK says that the array of historical data contains not only the OHLCV but also the data of the indicators (study) like ATR and RSI and etc but it does not say how to pull them. I need the volume profile.
