Tick spread

[StellaBot]

If I put in automation to bet a 4/1(5) horse with 10 ticks above it would bet at 5/1(6) if condition met However if the 2nd lay bet is set at 10 ticks below would it put in an order for 4/1(5) or 3/1(4)
Probably simple answer

10 ticks down from 5(4/1) would give you 4(3/1) because the tick increments between 5 ->6 and 5->4 are both 0.1 i.e 10 ticks, below 4 and above 6 your increment steps change
