I will be stunned if traders get this stock to hold above $4 US until the end of Friday, if this is anything like last month monthly options expiry.
If it is like last month and I wanted to make a quick buck I'd buy (more) shares now, or Friday, because next Monday it will be let loose for another dollar US gain.
Not advice, just an observation.
A lot of pressure on it now... but the walls come up quickly..
