Nifty has potential of testing 3650- 3670 region. But, a correction is possible from this region. Initially it could test 3580.
The stop for the longs is 3610. On contrary, if it continuously moves above 3670 region, hold your positions with a close stoploss.
But, as I have said earlier, Nifty is forming a big base for a strong rally in coming trading sessions and it has potential of moving towards 4000 in a very short span of time.
