Stocks Under F&O Ban on Nifty Weekly Expiry

Why Are Stocks Put Under the F&O Ban? 

The F&O ban is triggered when open interest in a stock's derivative contracts exceeds 95% of its MWPL. The rule is intended to keep excessive positions and speculative activity in check. 

Once a stock enters the ban list, traders cannot take fresh F&O positions. Existing positions can be squared off or reduced. Violating the exchange rules can result in penalties. 

The restriction becomes particularly relevant around expiry, when trading activity and volatility can rise sharply.
