Thats what the broker told me yesterday when i called them. i didnt want to make a silly move/execution and not be able to re purchase when this things really takes off...he said at this time i could sell but i would have to find someone else ( i assumed he meant trading platform) to re purchase...I would like to know at what criteria TDA would lift said chill so retail can buy this security through them...He didnt have an answere for that question :(
