I have done that before and it never got filled ei

They[TDAmeritrade] told me that some-one has to be willing to sell that many shares before Your/my order could be filled.
Maybe You put all or none on the order.
I do that.
Still yet, with all the shares traded today it should have been filled.
But it also depends on the ASK Price!
Sometimes there is a huge differential between the Bid and the Ask!
