Understanding the Ban
Everything you need to know about MWPL, the 95% ban trigger, and how it affects your trading.
When a stock's total open interest in its futures and options contracts crosses 95% of its Market-Wide Position Limit (MWPL), NSE places it in a ban period. During this period, traders across the entire market are barred from opening any new F&O positions in that stock — you can only square off (exit) positions you already hold. The restriction applies to the derivatives segment only; the underlying stock continues to trade normally in the cash market.
MWPL is the maximum number of open F&O contracts allowed in a single stock across all market participants combined. It is calculated by the exchange from the stock's free-float shares and liquidity, and serves as a systemic risk-control cap. By limiting how large the aggregate derivatives position in one stock can grow, MWPL prevents excessive speculation and protects the market from concentrated, destabilising bets.
The ban is triggered the moment aggregate open interest reaches 95% of MWPL. It does not lift immediately when positions reduce — the stock remains banned until open interest falls back below 80% of MWPL, at which point fresh positions are allowed again. This gap between the entry (95%) and exit (80%) thresholds prevents stocks from flickering in and out of the ban list on small intraday swings.
Ban-period stocks often see sharp, illiquid moves because fresh hedging and directional positioning is frozen — only exits are allowed. Many traders treat entry into the ban list as a signal of overheated speculation and elevated volatility. If you hold a position in a stock that enters the ban, plan your exit carefully, since you cannot add to or re-enter the position until it clears. You can always continue to trade the stock in the cash segment, which is never affected by the F&O ban.
