Option and Database tradingTo study an option chain, focus on the current market price, displayed in the centre. Analyse the built-up data to understand market direction based on recent changes in open interest and price. ITM call options are typically highlighted in yellow, making it easier to distinguish them from other options.
The put-call ratio measures trading volume using put options versus call options. Instead of the absolute value of the put-call ratio, the changes in its value indicate a change in overall market sentiment.
