Why is there a red triangle showing above the Staking box?
The Gambling Commission requires explicit approval to use staking plans that adjust the stake to compensate for previous losses, so you must explicitly activate recovery staking plans before you can use them in TheBetEngine.
To activate recovery staking plans, you should click on the Settings menu, go to the Betting tab and then tick the Enable Recovery Staking Plans checkbox. You will be asked to confirm your action.
Once recovery staking plans have been activated, the red warning triangle will no longer appear above the Staking box and you will be able to select from all of the available staking plans.
