During the F&O ban period, no new positions are permitted for any F&O contracts in that stock. The stock exchanges set the market-wide position limit, which is the maximum number of contracts that can be open at any moment (open interest). Thus, the F&O contracts of that stock enter a ban period if the open interest exceeds 95% of the MWPL.
