How to read the TATASTEEL option chain
Calls are on the left, puts on the right and strikes down the middle, with the at-the-money strike highlighted. Calls below the price and puts above it are in the money (shaded). For each option you see its premium (LTP) and its change since the previous close, open interest and its change, volume and implied volatility.
Open interest shows where positions are held: large call OI above the price is usually read as resistance and large put OI below it as support. The ATM straddle - the call and the put at the ATM strike together - is what the market charges for a move either way, so its price over the underlying is the move the chain is pricing in by expiry.
