Nifty closed above the channel yesterday, which confirms short term trend reversal.
FIIs sold index Futures and Calls but shorted 2.5 times more Puts than calls. This conveys that downside is limited. If Nifty crosses the resistance zone of 19445-19465 on hourly chart, we can see another 100 point up move. Downside seems restricted to 19324 in short term.
