"Booking Source" = "Direct" applies the Auto Actions only to bookings from your own web site, manually added bookings and bookings imported though the API (not the channel manager). If you want to apply and Auto Action only to manually added bookings add your username in the "Referrer" field.
"Trigger Time" defines when the action is allowed to start. Once it has started it is allowed to go for the "Trigger Time Window" period. When the "Trigger Time Window" period has elapsed the auto action stops.
Both "Trigger Time" and "Trigger Time Window" are relative to a "Trigger Event" i.e. check-in, check-out, time of booking.
