Payouts are not processed after 6 PM because, as per SEBI regulations, brokers must transfer all client funds to regulatory authorities at the end of each trading day. This process ensures compliance and proper fund management. The funds are returned to the broker on the next trading day, after which they can be used for trading or withdrawal.
Since all funds are upstreamed, payout requests made after 6 PM are queued and processed on the next settlement day. If you need urgent funds, placing the request before the cutoff time is advisable.
