The Margin Cushion is calculated as the account’s Excess Liquidity divided by the Net Liquidation Value. The Margin Cushion number is a tool you can use as a quick reference to monitor how much Excess Liquidity you have left before the account is in margin violation.
The Margin Cushion can be added to the TWS Trader Dashboard. To add the Trader Dashboard in Classic TWS, click on View menu option followed by Trader Dashboard. Right click on the Trader Dashboard and select Configure. When the window populates, click the Add Account Data button. In the pop up window, scroll down to "Other" and click on "Cushion" followed by "OK". Click Apply to save your changes and OK to close the window.
