The volatility is high...it means index option trades have a big range and hence can be hero zero kind of trades. The last 4 days have been gap up or down which is not good. It shows indecisiveness and also fear. It is not good sign.
Nifty. The rejection near 17550 was surprising. I was expecting another 70 odd points before some pullback. The current gap down as suggested by SgX is a result of weak currency markets and some volatility. Resistance is placed at 17460 and support at 17250.
BankNifty. 40500 is a big resistance and support comes in at 39850.... should be a weaker index.
Derivative. Data is weak for the day. Some put buying and today expiry day suggests a decent gap down and weakness.
Highly volatile day.
