If we go below 5320/5300... it will be confirmed that wave 2 or b is not yet over.... n mostly we will then go lower than 5171..becoz then the b wave of the current move(2 or b) will hv gone lower than the low of a at 5268(this implies more bearishness).....still I do not expect the downmove to go below 4985 as of now.
If we cross above the high made today at 5420/30.... then the downside will not take place.
