---THREAD ON F&O BAN---

📛 What’s F&O Ban?
Stock goes into ban when combined Open Interest (OI) of both Future & Options contracts across series & across exchanges exceeds 95% of Market Wide Position Limit (MWPL)

Reason for stock going in ban is to curb EXCESSIVE SPECULATION

📛 What happens when stock goes into ‘FNO ban’?
-One CANNOT take Fresh positions
-But CAN square off existing position

📛 Can you trade?

Yes, you can take ‘INTRA-DAY’ position ONLY if your broker allows

But If intraday position ‘NOT CLOSED ‘

Then exchange levies PENALTY of 1% of value of increased position subject to minimum penalty of 5k & max of 1 lakh

📛 When stock is in ban can you reverse an existing position in a stock that is in FNO ban?

'YES'

Example

-If you are long on 2000 Call strike of RIL
-Can reverse with opposite position by selling 2000 Call strike

📛 When does the stock come out of ban?

-When OI falls below 80% of MWPL

Note: Exchange releases MWPL data for all F&O stocks monthly

📛 WHAT IS MWPL?

It is lower of:-

-30x average no of shares traded daily in cash segment in the preceding month
