Current Maintenance Margin

Trading Term

This value shown in TWS displays the amount of equity that must be maintained in order to continue holding a position. In the U.S., the rules of the listing exchanges specify the maintenance margin requirements on security transactions subject to SEC approval.  The exchange maintenance margin requirement for long stock positions is currently set at 25% although brokers often establish ‘house margin’ requirements in excess of that, particularly where the security is considered low-priced or subject to volatile price changes.  The exchange maintenance margin requirement for short stock positions is currently set at 30%.  You can monitor your margin values in real time using your TWS/Mosaic Account Window.
