Time decay (theta) gradually reduces the value of Nifty 50 options as expiration nears. This effect is stronger for at-the-money (ATM) and out-of-the-money (OTM) options. If the price doesn’t move much, option buyers lose value over time, while sellers benefit from this decay as expiry comes closer.

The Nifty 50 Option Chain shows key details like strike prices, bid-ask prices, open interest, and trading volume. Calls are listed on the left and puts on the right. The at-the-money (ATM) strike is usually highlighted. Higher open interest often signals strong support or resistance levels in the market.

The ATM (at-the-money) strike is the closest available strike price to Nifty 50’s current level. These options have the highest time value, making them popular for traders who expect movement in either direction. ATM options offer a balance between risk and reward, making them a go-to choice for many traders.

ITM (in-the-money) options have intrinsic value. For Nifty 50, call options with a strike price below the current level and put options with a strike price above it are considered ITM. These options are more expensive but carry less risk than OTM options since they already have some built-in value.

OTM (out-of-the-money) options don’t have intrinsic value—they rely purely on price movement and time. Calls with a strike price above the current Nifty 50 level and puts with a strike price below it fall into this category. They’re cheaper to buy but come with higher risk due to rapid time decay.
