Frequently Asked Questions: Nifty Options & Derivatives

How do you read Nifty Put-Call Ratio (PCR) for intraday trading?

PCR is calculated by dividing total Put Open Interest by total Call Open Interest. When PCR drops below 0.70, the market is oversold and contrarian traders look for quick upward bounces. When PCR rises above 1.35-1.40, the market is overbought with excessive Put writing, indicating risk of profit-taking.

What does heavy Call writing at 24,500 Strike signify?

Heavy Call writing indicates institutional market participants and option sellers expect Nifty 50 to remain below 24,500 before the upcoming expiry. This strike becomes a formidable overhead resistance wall. Only an aggressive short-covering rally can breach this level.

Should retail traders buy or sell options on Nifty?

Due to Theta time decay, over 80% of out-of-the-money options expire worthless. Successful retail traders utilize hedged option strategies (such as Bull Call Spreads or Iron Condors) rather than buying single naked Call or Put options, protecting against volatility crushes.
