See a pattern emerging: TGLO was repeatedly knocked down to 0.37 early in the day, then someone would defend it at the end of day to 0.48-0.50. So a day trade strategy may be setting buy limit at 0.37, then ask for 0.48 at end of day. Volume is small, however it may be possible to make $1000/day. It is chump change, but may be entertaining while waiting.
