Today we observe very big movement in nifty. Its day's high was 10888 slightly higher than yesterday's high and day's low was 10729 lower than yesterday's low. Total gap between high and low is 159 and nifty closed 44 points lower but still posted big green candle with long but equal upper and lower leg. Though its low was below green line, it closed above green line. This is a positive sign. Tomorrow's green line value is around 10785. So nifty has to close above this to remain in channel. Else it will be closing below green line.
