One benefit of an EDGE membership is the ability to track parlays and teasers. First, go into your settings by clicking the gear symbol in the top left corner of the 'My Action' tab. From there, toggle on the 'Pick Stats: Include Parlays & Teasers' to have the stats reflected in your bet history.
To enter a parlay or teaser, add selections to your bet slip as you normally would.
When you go to save your picks, choose 'Parlay' or 'Teaser'. You can then adjust the lines for your picks and the payout as needed.
