Hi
Ticks are the increments of a selections price movement.
If a selections back price moves from 1.68 to 1.70 it has increased by 2 ticks
If a selection lay price moves from 2.08 to 2.06 it has decreased by 1 tick
Tick increment sizes are:
Price Tick increment size
1.01 to 2 0.01
2 to 3 0.02
3 to 4 0.05
4 to 6 0.1
6 to 10 0.2
10 to 20 0.5
20 to 30 1
30 to 50 2
50 to 100 5
100 to 1000 10
The trigger will lay if the price has increased by 5 ticks from 10 secs before the off
example:
10 secs before off fav back price is 1.84
in-play if the favs back price rises above 1.89 (5 ticks) it will lay
The market must be refreshing at least 30 seconds before the off
