    I need a custom bustabit betting script. I have a current one attached that is very basic. I dont want a martingale. I want the bets to go up 2 units when I lose and down 1 unit when i win. This will continue until I am in profit even 1 bit more than when I was at the start of the sequence. It will restart at the base bet every time it is in profit.
