On your Portfolio screen you will always see a Cash Available banner. Cash Available reflects the amount of USD currently in your account that can be used for trading or investments.
Please note: Outstanding limit orders impact your Cash Available balance.
For example, if you have $1,000.00 available in your account but you also have $100.00 in outstanding limit orders, your cash available will reflect a value of $900.00 - since your $100.00 order could fill at anytime.
In this example if you would like to free all of your cash for trading, you’ll need to find the open limit order in the Pending Trades section of your Portfolio screen.
Select the order, scroll to the bottom and select Cancel Trade.
