L2T
about elliot wave u asked ( ur qs. how far 4 th wave allowed to go deeper )
i am not a expert of EW, knew few things here n there so do confirm with google ( trivia about EW ..... its not a stock market indicator, Mr elliot devised for analysing crowd behaviour but it feets the market)
4th wave must not fall below the 52 % fib/ replacement of total price movement of 3 rd wave ( fig. is 3250 for nifty )
p.s. i think u were absent last week when we had a discussion on EW along with chart, dig it in free time
