Your cash available to withdraw may be less than your available cash balance for the following potential reasons:
Withdrawal Holding Period
If you deposit funds via ACH, that deposit will need to remain in your account for a minimum of 7 business days. If you deposit funds via wire transfer, this withdrawal holding period does not apply.
Settlement Period
Funds will not become available to withdraw before they have fully settled. Stock, ETF, and options trades currently settle on a T+1 basis.
Required Margin Maintenance
NYSE/FINRA rules require investors to maintain a certain minimum amount of equity in their margin account at all times.
Pending Orders & Frozen Funds
The funds used towards pending open orders may be locked in your trading account and would not be available for withdrawal.
