When available on a particular security, weekly and quarterly options can be enabled for viewing and trading on the options chain. First, log in to your OptionsHouse account. Click on the "Manage Accounts" tab at the bottom of your OptionsHouse account screen.

From the Manage Accounts screen, select the Preferences tab, and the Chain & Quotes secondary tab.  Then check the boxes next to Quarterly and/or Weekly options.

Finally, click the "Save and Close" button.

Weekly and Quarterly options can be viewed in chronological order (by expiration) on the option chain.  Weekly-series options are offset by a red heading; quarterlys are offset by an orange heading. Throughout the platform, Weeklys and Quarterlys are designated by either a (W) or a (Q), respectively, and always include the expiration date in their description.
