Only if charts could talk...!!! just look at yesterday's low on my charts.
that support line was indicated 1 week back.
now breaking 4481, we will see 4420(jan's low) and then 4377. any shorts should now have a SL of 4481.
however if nifty finds support at any of these levels, nifty has to sustain 4641, for any upward rally.
so with so many resistence levels on upper side, its always wise to wait for any rise to short again.
