I never went through this thread I use VSA too still in the learning phase. Would love to contribute on this thread. Also I dont quite agree with you that the Cash decides the futures its mostly the other way round backtest it and you ll find what I mean. But nevertheless commendable job and I ll hopefully learn a lot from you. Yesterday although market went down there were no volumes to support it also if you see the volumes today after 1330 it was massive especially in most of the stock that took a hit and were down yesterday and today. Check ABAN, DLF, UNITECH, NIFTY FUTURES etc.
