i think the oi logic may fail today..i mean the chg oi numbers may reverse..
a very similar thing had happened on wednesday also... for 4 hrs nifty was between 10770 and 10830... but during those 4 hrs, CE oi was continuously rising, whereas PE oi was remaining flat or reducing.... n then finally the fall started after 2 pm .... oi just tells us direction for the day.... actually i was unknowingly using the ORB strategy
.... bcoz in orb also we look at price for the first 15 , 30 or 60 mins.. n then trade in direction of breakout... but instead of price, i look at oi
