Margin Requirements

To view real-time margin requirements

From the Account menu, select Account Window.
The Account Information window shows your account details, including the current market value and portfolio.

To check projected margin requirements under the Portfolio Margin model, click the Try PM icon. Portfolio Margin uses a risk-based model that may result in lower margin for balanced portfolios with hedging positions. Existing customers can upgrade to a Portfolio Margin account via Account Management.

Margin Warning

To help you stay on top of your margin requirements, we provide pop-up messages and color-coded account information to notify you that you are approaching a serious margin deficiency. TWS will highlight the row whose value is in the distress state. The colors on your account screen tell you the following:

Yellow - You have only a 5% cushion above the margin requirement.

Note: If your account equity moves rapidly from a greater than 5% cushion to a margin violation, your positions may be liquidated without you receiving a yellow warning.

Orange - Your margin cushion is depleted and you have a short time to enter into margin-reducing trades before your positions are liquidated. At this point you will not be able to enter into any trades that might increase your margin.

Red - Your positions will shortly start to be liquidated as necessary to bring your account back within the margin limits.
