Dusty - INSN. I filed a complaint with Ameritrade as well cos the cuntz were doing the same thing.
They told me they had restricted trading due to word from their brokers. The brokers probably said "we are getting screwed and if you want any favours from us in future, you had better put a halt to the buying that is firing up this run".
I complained with the SEC as well by phone and by e-mail to frosts@sec.com (mr frost)
