Why is intraday trading not allowed for contracts if the underlying security is under a ban period?

Intraday trading is restricted for contracts when the underlying security is under a ban period due to regulatory guidelines. According to these guidelines, clients are not allowed to open new positions or conduct intraday trades in F&O contracts of securities during this period. However, clients are permitted to close out existing positions.
