Example as requested:
1 - Lay bet on second favourite, odd 3, value 1€, and loose this bet (lost 2€);
2- To recover the lost money, dutching 1st, 2nd, 3rd and 4th to recover the losses (2€ in this case);
3- Here i will have two diferent scenarios:
3.1 - If i loose again, in the next bet i want to recover all (2€ from lay bet + the losses on dutching) at once. And this will continue until i recover my money.
3.2 - If i win, i want to re-start betting on lay second favourite.
This is a trigger to use on greyhounds.
