don't buy during the day

I just got swept up in the natural gas craze and jumped in and bought
SWN at $35.25, which will probably turn out to be the high for the day.
I also thought about doing a smaller volume test buy, then waiting for a
follow up, but though, "nah, it's up 7% on the day, that's enough of a
signal." I better set my stop close on this one.
