Alchemist is the one to ask, he's been using TS for years. I've only been using it since last Fall. They do have a Chaikin Oscillator and OBV in the indicators list. You can change the input on most indicators to customize them, but don't know that these are what you are after. Still fooling around with various stuff TS offers. Haven't found any of their built-in strategies of use to me so far, but perhaps I am not applying them correctly.
Sorry I couldn't be of more help, but check with Alchemist, he might be better able to assist. Good luck!
