Sahi withdrawal is typically processed within the same working day or the next working day depending on the time of request.
Once funds are settled, withdrawal to your linked bank account is processed within 24 hours. Most users receive funds same-day if the request is placed before 1 PM on a working day.
The settlement cycle (T+1 for F&O and intraday, T+2 for delivery) is a SEBI mandate that applies across all brokers — it is not a Sahi-specific delay.
