When you deposit funds from your bank account, you should see funds debited from your bank account within 1-2 days, and funds will usually "post" (become available to withdraw) to your Anchor account in 2-3 business days. However, for certain banks, funds may take additional time to be available to withdraw. Anchor assumes the payment will succeed and instantly credits your account for this transaction, allowing you to trade right away.
Occasionally, the payment will fail, at which point the bank notifies Anchor and we reverse the instant credit for this transaction.
