Its a Very Complicated Extenstion wave on Nifty Upmove, Shows a Consolidation for sw(4) needed on the Expiry Day.
I have mentioned a two possibilities here. If today's low 4945 is held then a Possible upmove upto 4990 before a fall for sub wave C. Else if broken may lead to a fall upto 4915 to complete the 4th sub wave. Lets wait for the Results on Expiry Session. Cheers.
