This is a key page in your account for managing anything to do with automation and tracking.
On the far left, placing a tick will put the model into your bet feed for automatic bet placement via BF Bot Manager.
Next you will see the System / Model Name.
You then have another option to select a tick box, which will automatically push selections to your Bet Tracker tool.
The final two columns are the model source (E.g. System Builder, Prediction Models, Match Shortlist etc) and the Tipster Name, which is, again, used in BF Bot Manager to connect your Strategy to your Selections List in the feed.
You can also manually add selections on various parts of the site if you prefer, but generally the automation is advised. Here are a few examples on how you can do this manually.
