Not a sebi registered analyst, and these are just my thoughts, and readers should take their own judgement.
Nifty's opening 78 points down at 19655 (below short Target 19667 we mentioned yesterday)
Nikkei's down almost 2%. US markets didn't show similar weakness yesterday, but the futures are showing weakness.
I would be careful before going long.
Fresh long only above 19700-19720 levels.
I would also wait a bit before going short, may lose some profits, but safeguard the capital.. anyone should their take their own judgement.
Good luck
