Quick relative to SP question

[jamesedwards]

Quick Q for the Guardian experts. What happens if you set a rule to lay in-running at 50% of SP when SP is less than 2.0?

eg an SP of 4.0 would set a lay at 2.0, but an SP of 1.8 would try to set a lay at 0.9 which is impossible?

Presumably it works on the liability/profit

So if you're backing
50% of 4.0 would be 2.5 (eg £100 @ 4.0 profit = 300 and £100 @ 2.5 profit = £150)
50% of 1.8 would be 1.4 (eg £100 @ 1.8 profit = 80 and £100 @ 1.4 profit = £40)

eg (price + 1) / 2

There is the option of adjusting by 'Percentage (using -1.0)'
