still it in a range.....cannot say whether bigger range as 2660 to 3150 ...or 2750 to 2870..but if up move continues here are few thoughts...1)sensex fall from 10470 to 8631=1839...2) if we retraced 61.8% then it comes @ 9768...3)if we retraced 80 % then it comes @ 10103..if we take nifty..then 61.8% @ 2960 and 80% @ 3049these points seems important...all depends upon next week....the bigger fall may not come in february series...lets see. 
here is nifty daily
weekly scrip.......ongc..
if market remains positive there are chances of ongc crossing 700...may touch 740.....sl for positional....658.
