This option allows you to set a rule to arm at a time AFTER the first rule within the automation file has triggered, this is handy if you first want to trigger a series of bets then allow a bit of time for the market to move in your favour before triggering a green up rule.
In the image below you can see it is armed for 00:00:59 after the first rule of the file triggers until 00:02:00 after the first rule has triggered.
