flipping works on the way down, as well. you basically make the same margin either way. however, if the prices update during the 4 hour downtime, rising items gain extra profit, while falling items lose profit. conversely, if your item reaches a critical point, a rising item loses profit, while falling items gain profit. rising items: best to flip if you think or otherwise are reasonably certain that they will continue rising for the near future and/or the ge will update in the next 4 hours falling items: best to flip if you think there is a reasonable chance the price may change direction and/or the ge will not update in the next 4 hours
