What is f & o expiry
F&O means futures and options- These are trading tools related to the derivatives of the stock market. Now let’s talk about what expiry means. When you buy a futures or option contract (F&O contract), it has a fixed time frame. The last day of that limit is called “expiry day”. For example-if you bought F&O contract for the month of June, then its expiry usually takes place on the last Thursday of June. By that day you have to either sell that contract, or it will be closed automatically.
What happens on expiry Day?

Trading volume is very high because many deals are expiry on the same day.

This day is very important for traders in the option because it is here that profits or losses are fixed.
How many types of expiry occur in F & O?
