RSI+OBVthis strategy works on the basis of crossovers of RSI at different period and OBV at different periods (separately). I am using it for Nifty and Bank Nifty. Entry for long can be taken when green bar appears; and exit has to be done when it disappears. Entry for short has to be taken when red bar appears; and exit has to be done when it disappears.
With little help from price action good results can be achieved.
