How to calculate greenup price on ladder

[keith.wheeldon]

Hi

I am trying to improve on an automated strategy. I would like to calculate what the green up or red value will be on the ladder when I take some of my money out as the price rises or declines.
e.g I place a Lay offset bet of 5 ticks with a stake of £10.
When the price moves up 1 tick I place a back bet of £2.

How can I calculate what the green up value will be at each price on the ladder.

Hope this makes sense.

Thanks-Keith
