Nifty is expected to remain highly volatile in the upcoming week due to multi-event and news flow week. On a weekly basis, my view remains that if Nifty tests any imp short covering level, then we can expect strong short covering making Nifty close in green on a weekly basis. Imp short covering levels on the downside are: 1.)22803 2.)22460 3.)22338 All levels are marked in the chart posted .
