Delta using DataContext / index in SDK

[unfinishedtrade]

Make a way to get bid/ask volume or delta without using onTick() and isAskTick(). If possible just be able to do something like .getAskVolume() / .getBidVolume using DataContext and the index

i noticed the delta volume inbuilt study gives delta info in the cursor data window. Is it poss to get the info from that?
