I don't know. Yesterday, the weather report said "normal or warmer" temperatures in the northeast. That' was my cue to short it. This morning, @7 A.M., it was down 2 cents, so went back to sleep. Got up @ 8:30, and the weather report had changed to colder temperatures, and it was moving up, so I covered. It went way up, so I was glad I got out, but just saw it crash. Someone's manipulating the weather reports.
