Offset bet with greening vs. separate rule for greening up

[jaipal2004]

Hi,

still trying to get to grips with the bot trading and wondered what the difference is / why you'd use the following :

Offset bet - Rule 1
Green up - Rule 2

vs.

Offset bet with greening all in the same rule

Probably a very simple reason for my proably stupid question but I need to ask !

What happens if your offset bet doesn't get matched?
