# Permissible Pairs Ladders

Permissible Pairs Ladders refer to the predefined combinations of odds ranges that can be configured within a template to ensure compatibility. The odds will then not be fixed using the margin, but instead will have a table of odds pairings.

There is a list of predefined ladders to choose from, and those can be viewed in the area shown below.

If you need additional ladders, you can create them in the same way as Single Odds Ladders. Click “Add New PP Ladder”, and in the pop-up window, enter the required values.

#### Note regarding US odds

To use Ctrl in US format and get these odds sent on the feed, we provide predefined US odds ladders. The values are stored as decimal odds in our system, but the Ctrl interfaces convert them to US format odds.

If you would like to have your own customized ladder, you can send it via Support in Excel format, and it will be uploaded to your account.

The sequence of actions for converting to US odds looks as follows:

1\.     Decimal odds are calculated in the fair odds key

2\.     Fair decimal odds are converted to odds key-applied odds

3\.     These “keyed” decimal odds values are converted to US odds

4\.     US odds are converted to rounded US ladder odds

5\.     Odds harmonization is applied

Please note: To achieve accurate odds values, the number of decimal places you provide is vital. We recommend 8 digits or more behind the comma. The feed can provide this, but you should make sure your system can handle the number of digits accordingly.
