Max liability fixed units

Hi
in the backing trigger amount field you can edit the formula to use an IF statement, for example max liability 30.00
IF(bet_size + current_lss/(back_price-1)<30.00, bet_size + current_lss/(back_price-1), 30.00)
but I don't know what that will do to the recovery, please test in test mode.

if you have exact requirements for modifying this trigger maybe its better to put in a trigger request 

I was just looking, the trigger seems to be fixed unit initial bet, not percentage of bank, are we are talking the same trigger:

ok, this is the over / under martingale where you need to load all the over / under markets. I was confused by your first post about goal lines because there is another martingale for the goal lines market.

this trigger is laying, the formula for fixed liability for laying is: liability/(lay_price-1)
e.g. 30.00/(lay_price-1)
for a fixed liability of £30.00

Like above you can try using an IF statement

this is what is currently in the amount field:
init_bet + current_lss/(1-commission)

IF(init_bet + current_lss/(1-commission)<30.00, init_bet + current_lss/(1-commission), 30.00/(lay_price-1))
