Feb expiry series is just 4 trading days away and SGX nifty show feb trades at 2924 (14311 contracts) thats 241 points from current close??? is something wrong with the data?

one freak trade at today's open....
look at open, high & low - all at 2924

now come to ground zero - look at bid & ask
bid = 2540
ask = 2745

don't pay too much attention to near month contracts in SGX....

also look at
OI = 15108
which is less than
volume 15546

some serious data mismatch
