There is no minimum period that a SatrixNOW client is required to hold an ETF for. You can sell an ETF immediately after receiving the trade note (by way of email) confirming the execution.

When you sell an ETF, it will take up to 5 (five) business days after the date of trade, for the proceeds of the sale to be paid into your account

This is in line with the JSE's Equities Rules which currently works on a settlement period of 3 days after the date of the transaction (referred to in Investment terms as T+3) and the SatrixNOW Terms and Conditions which make provision for a maximum of 5 business days for settlement to allow time for conclusion of our settlement processes.
