Funds from your security tokens trading activity are available for withdrawal immediately after a trade has fully settled (user accounts are credited and balances are updated). This occurs when the banking partner that holds user funds receives confirmation that the token has transferred from the seller to the buyer and completes the reconciliation of the buyer and seller accounts.
Note that a settlement is not instant and that the INX ONE platform utilizes US-based banking systems, regulations, and hours. Please read the INX Funds Availability Disclosure for more information.
