The market events tree can be accessed from the Main menu -> View -> market tree link or by clicking the icon on the tool strip.

The Betfair market tree displays the current markets available for betting within the Betfair system. The markets are displayed in a hierarchical structure, with the categories at the top of the tree displayed on blue tabs.

To expand the top level category simply click on the category, of interest and it will be opened, listing all the child categories.

Once the market of interest is displayed in the market tree, click on it and BetGizmo will begin monitoring the market for you, loading all relevant data into the forms that are currently displayed.
