Trigger nodes are a way to specify when the workflow will start.
You can always run a workflow in manual mode. This will push ALL channels down to the next node and you can do this even when your workflow is Inactive.
When you are happy with your workflow canvas and want torq to automate the workflow then please Active the workflow on the top left corner.
This Interval trigger node will start the workflow at a certain interval. An example for this would be every 15 minutes. The trigger will push ALL channels down to the next node because this is a time based trigger.
This trigger node is also time based but rather then running at intervals you can specify the start times via a cron format. The trigger will push ALL channels down to the next node because this is a time based trigger.
This trigger node fires every time the balance of a channel shifts. Because it's based on 1 channel only 1 channel will be pushed down to the next node.
This trigger node fires whenever a new channel got confirmed. Because it's based on 1 channel only 1 channel will be pushed down to the next node.
This trigger node fires whenever a channel got closed. Because it's based on 1 channel only 1 channel will be pushed down to the next node.
