Shares of GLUU have been rallying in the past couple of weeks. This comes after sliding from a high of 4.00 in February to a low of 1.73 at the end of October.

A trade from 2.00 should probably take some profit before reaching 4.00 in case the current rally is just a "dead cat bounce", which would be followed by a bearish continuation swing that will break through the noted critical support.
