I need some clarification of your trigger description.
You want to lay on a greyhound and then back to generate a 2 ticks profit.
At the same time you want to apply a 2-step recovery plan. This means you want to recover all previous loss in 2 bets.
But if you expect to generate profit from green-up, i.e. just 2 ticks, then in order to recover the loss, you will have to place huge bets.
Example:
1. You lay €10 at 4.0. Lost, -€30.
2. Suppose the price is now 3.0. To recover €30 in 2 steps, you need to earn €15 from each market.
If you lay at 3.0 and want to back at 3.1 to earn €15, then you will have to:
LAY €465 at 3.0
BACK €450 at 3.1
Therefore, the liability of your lay bet will be 465*(3.0 - 1) = €930, and this is just after the first loss!
Please consider what I wrote above and let me know if you want to change the conditions of your triggers.
