There is no minimum period of investment. Investors may choose to close their Invest Account any time they choose.
For example, the investor has chosen to copy trade from Strategy Manager A for one week and has decided to copy trade from Manager B instead. The investor can close the Invest Account linked to Strategy Manager A and open a new Invest Account to copy trade from Strategy Manager B immediately. There's no restriction or penalty for closing an Invest Account.
As for withdrawals, an investor may also choose to withdraw from their Invest Account at any time, either partially or a full amount. If there's profit on the Invest Account, the Profit Share due to the Strategy Manager will be deducted when the withdrawal is requested.
