Can OTS accept a bet with a custom price, or is there a boosted-odds feature?

No. OTS cannot process bets submitted with custom odds – such tickets are rejected. There is currently no boosted-odds feature, and none is planned in the near future. The only built-in way to adjust pricing is via the margin on templates, which applies to all bettors on the account rather than per player or per selection. If you want to display “boosted” odds to your players, the usual approach is to send us the regular (correct) odds so the ticket is accepted and risk-checked normally, and then handle the boost on your side by recalculating the winnings and paying the difference to the player as a bonus. We do not recommend bypassing OTS, as the ticket data is also used for invoicing.
