3. Backing £10, and if the bet lost, adding £10 to every next bet until it wins, then reverting to the original bet size. For example, 10, 20, 30, 40, etc.

Amount: IF(last_lost=0, 10, 10+hist_1_backa)

For laying:

Amount: IF(last_lost=0, 10, 10+hist_1_laya)

4. Laying £10 and doubling bet size after every 2 losing events, till the bet wins. Then stopping. Example: 10, 10, 20, 20, 40, 40

Amount: IF(last_won=0, 10, IF(AND(last_lost>0, losses%2=0), hist_1_laya*2, hist_1_laya))

Condition to add to the trigger:

Total Won Amount is equal or less than 0

5. Add winnings from a back bet to the next bet size. Reset the bet amount to the original value if a bet loses. Example: 10@1.4 (won), 14@2.2 (won), 16.8@4.5 (lost), 10

Amount: IF(last_won>0, 10 + hist_1_pl, 10)

You can modify this to stop after a certain number of consecutive wins. For example, to reset the bet size to the initial £10 after 3 wins in a row, change the "Amount" field to:

Amount: IF(AND(last_won>0, wins<3), 10 + hist_1_pl, 10)

6. Backing to the profit of £10, then if the bet lost recouping the losses plus 50% of the initial profit target. I.e.: £25@1.4 (lost), £33.33@2.2 (lost), £20.95@4.5 (won), £10 etc.

Amount: IF(last_lost=0, 10/(back_price-1), (10+last_lost + 5)/(back_price-1))

7. Doubling bet size after each loss, i.e. 10, 20, 40, 80 etc.

For backing:

Amount: IF(losses=0, 10, hist_1_backa*2)

For laying:

Amount: IF(losses=0, 10, hist_1_laya*2)

8. Backing/laying according to Fibonacci staking plan

For backing:

Amount: IF(losses<2, 2, hist_1_backa+hist_2_backa)

For laying:

Amount: IF(losses<2, 2, hist_1_laya+hist_2_laya)

9. Backing to the profit of £10, then recoup the losses in the next game so as to win the target £10 and recover the previously lost amount. I.e. £6.67@2.5 (lost), £20.84@1.8 (lost), £31.26@2.2 (lost), £102.64@1.67 (won), £5.0@3.0 etc.

Amount: (10 + last_lost) / (back_price-1)

10. Laying on a selection, then recouping the loss according to the following plan (commission not included).

Add 1/4 of the loss to the next four bets. If all of them won, revert to the original lay amount. If at least one of them lost, then adding 1/4 of that loss to the next four bets and so on. Example: £10@2.5 (lost £15), £13.75@5.0 (won £13.75), £13.75@3.35 (won £13.75), £13.75@1.9 (lost £12.38), £13.09@4.8 (won £13.09), £13.09@2.0 (won £13.09), £13.09@2.6 (won £13.09), £13.09@2.8 (won £13.09), revert to £10. Overall P/L: £52.48

Amount: IF(last_lost>0, X+last_lost/4, IF(OR(wins>3, wins=0), X, hist_1_laya))

Replace X with the initial amount of your stake, for example 10.

11. Laying to a fixed liability, then increasing it by 10% after each loss and reverting to the original amount after a win. Example: £125@1.8 (lost £100), £91.67@2.2 (lost £110), £161.33@1.75 and so on.

Amount: IF(losses=0, 100, last_lost*1.1)/(lay_price-1)
