Strange thing happened just now, placed a buy order on E*trade...

Strange thing happened just now, placed a buy order on E*trade to buy more PRE shares, I already own a large parcel of them. Put in the buy order at 0.011 for 20,000 shares, the offer to sell is at 0.11 so assumed no problem, there are 25 buyers at 0.010 but all of the day's trades have been at 0.11 bar one 10,000 parcel at 0.010

My order was rejected by a designated E*trade trader, was told my 20,000 parcel wasnt large enough that I would need to buy more if I wanted them at that price??

Seems very strange when all I was wanting to do was buy at the offered price. I cant see why they would reject a buyer of a company's shares.

Very frustrating
