I could not tell you. I use TDA and had no problem selling 1mm on wed to test it out, it sat for 3 hours but then did sell before days end, so I could not tell you why yours did not sell.
VarmIt - seen these large volume sales days in a few pinks b4...one of them with much larger numbers...as with them and imo it is nothing more than insiders selling free trading shares at the 5th digit which are then sold to eager shareholders at .0002 and occasionnaly someone may get a .0001 buy but not very often when some r willing to pay .0002...aimo most shareholders won't b able to sell at .0001 until my presumed theory plays out...jmo from my experiences in lotto world...
