Demand Zone! Look at the last 3 times it has reversed from here. Huge volume indicates selling climax and end of down move. Good accumulation zone and we might not see these levels again.
Nifty should fall lower after testing 7250, you can check my link how it fell from 8500 to 7850. This downmove will be quick and might signal the end of the bear market at 6350. If 6350 breaks will go in a long term bear with targets to the downisde of 4500 by December 2017.
Nifty constantly making lower lows and lower highs and looks bearish for the time being with the first target being 7850 and stop loss at 8500. Seems very likely it will break through 50 DMA and 200 DMA on closing basis. Target 7850 , Stop 8500 Risk reward: 3:1
