As the price rose, the cumulative Open Interest (OI) of Nifty futures increased – it went up to 189.9 lakh contracts on March 28 versus 161.2 lakh contracts on March 22. This indicates a long build-up.

The Put Call Ratio (PCR) of Nifty weekly and monthly options stands above 1. A ratio above 1 is bullish, as it shows traders have sold more put options compared to call options. Participants sell puts when they are optimistic.

The chart of Nifty futures shows a potential for the rally to extend to 22,750, a resistance. The hourly chart shows the confirmation of an inverted head and shoulder pattern. As per this chart set up, the contract can rise to 22,750.

There could be a corrective fall from the current level, possibly to 22,350, before it surpasses 22,580 from here. So, traders can consider long positions.

Strategy: Stay away for now and buy Nifty futures when it moderates to 22,400 and 22,350. Place initial stop-loss at 22,180. When the contract moves above 22,580, alter the stop-loss to 22,400. Tighten the stop-loss further to 22,500 when the contract touches 22,650. Book profits at 22,750.

Alternatively, one can buy call options. Consider buying the 22,200-strike call option (April 25 expiry) (₹476.90) when its premium drops to ₹400. Place stop-loss at ₹280. When the price rises above ₹530, tighten the stop-loss to ₹420. Exit at ₹620.

Bank Nifty

Bank Nifty futures (April expiry) closed at 47,545 on Thursday, thereby posting a gain of 0.5 per cent for the week. But unlike Nifty futures, the cumulative OI of Bank Nifty futures saw a decline – it dropped to 50.2 lakh contracts on March 28 as against 55.8 lakh contracts on March 22. A rise in price along with a fall in OI implies short covering.

So, traders can wait before initiating fresh longs.

Strategy: Go long on Bank Nifty futures if it falls to 47,200. Keep an initial stop-loss at 46,300. When the contract rallies above 48,000, tighten the stop-loss to 47,300. Liquidate the longs at 48,600.

For lower risk and margin obligation, traders can consider buying the April 24 expiry 46800-strike call option, which closed at ₹1,183.75 last week.
