How long is the settlement period for US trades?

The US stock exchanges follow a T+1 settlement cycle for Equities and ETFs, and a T+1 settlement cycle for Options.

Settlement and delivery of stocks occur 1 business days after the order is executed. Whilst the settlement and delivery of options occur 1 business day after the order is executed.

Example: if you sell your US stocks on 18 January (US trading day), the settlement date will be 19 January (US trading day). You can then initiate a withdrawal or currency exchange instruction. If the settlement date falls on a holiday, it will be postponed accordingly.
