Martingale - Variation

Hi. I'm trying to make a Martingale variation work. It works like this:
- Starts on Lay Over 2.5;
- When the first goal happens, it enters the market 3.5, where the liability should be: "Market liability Over 2.5 + market liability Over 3.5". Without leaving the market Over 2.5;
- And so it should be with the other markets.
It turns out that I do not know how to refer to the value of the liability that is circled in the attached image. On my trigger, there are my unsuccessful attempts. As you can see in the image, after the first goal happened, the trigger entered the Over 3.5 (Ok!) Market, but with the init_bet value.
Thank you for any help.

Hi
liability on a lay bet is matched lay amount * (matched lay price -1)
so the formula: bm_laya*(bm_layp-1)
 

...and

I think for your need you can also use variable: market_min_pl

Hey there, I'm trying to do the same thing. Did u manage to do it ?
