Components of Option Chain
ITM (in the money) options

If the strike price of a put option is greater than the current spot price of the security, it is considered to be ITM.
ATM (at the money) options
If the strike price of a call option equals the current spot price of the security, it is said to be in ATM.
If the strike price of a put option equals the current spot price of the security, it is said to be ATM.
OTM (out of the money) options
If the strike price of a call option is greater than the current spot price of the asset, the option is said to be out-of-the-money.

Open Interest – Changes in Open Interest
The open interest will rise if both trade participants initiate a new position. The open interest will decrease if both players are liquidating an old investment.

However, if one party initiates a new trade while the other liquidates an existing trade, open interest remains unaltered.
Never believe that when the price rises, more Longs will be generated than Shorts. Longs will always be equal to Shorts, it’s only that Longs are outperforming Shorts in the transaction, which is why the Price is rising.
The number of shares purchased is always the same as the number of shares sold. So, what causes the price to climb or fall? Due to purchasing pressure or selling pressure. So, if buyers outnumber sellers in a contract, the price rises; if sellers outnumber buyers, the price falls. Buyers, on the other hand, will always be equal to sellers. As a result, open interest is increasing, which indicates that new contracts are being added. However, because the price is increasing with it, Longs are dominating the trades. As a result, the market/share is strongly bullish. The inverse for a negative trend.
Writing is more important
Writing holds greater significance in trading due to the need for conviction in facing unlimited risks and requiring substantial capital. Sellers, often represented by big institutions, possess significant financial resources and are typically considered more informed. On the other hand, buyers, commonly retail traders, are attracted by the convenience of lower capital requirements. The belief that institutions are usually right underscores the importance of selling. Additionally, a high level of open interest in options signals a substantial bet against the corresponding strike price, emphasizing the significance of selling positions.
| Option | Meaning | Result |
| CALL OI | Sellers are betting market won’t go up | Bearishness |
| PUT OI | Sellers are betting market won’t go down | Bullishness |
Identifying Support and Resistance based on option chain open interest
Support and Resistance
- When call option Ol created
- Some big is betting it won’t go above that mark
- They are most likely right
- High chance the strike level will not be crossed
- The level usually acts as a resistance zone
CALL OI = RESISTANCE
When put option Ol created
- Some big is betting it won’t go below that mark
- They are most likely right
- High chance the strike level will not be crossed
- The level usually acts as a support zone
PUT OI = SUPPORT
To identify support and resistance levels or zones using open interest (OI):
Firstly, look at the highest open interest (OI) column on both the call and put sides of the options chain. Then, take note of the corresponding changes in OI. For support, focus on the put side where you find the biggest open interest number with a positive change in OI. This indicates strong support. On the resistance side, look at the call side for the largest open interest number with a positive change in OI, suggesting a robust resistance level. In simpler terms, you’re identifying key support and resistance levels based on the highest OI numbers and positive changes, helping you gauge potential market turning points.
Price trading at 21,700 is Resistance if broken net resistance is at 21,800 and 22,000 where strong support is at 21,500.
