Yes Steve, it was a good scam. Breaking news on a stock, the specialist freezes the book 1x1 and ecn's are crossing it up 50 cents. You could hit the specialist's 'frozen' 1 lot offer for 99 shares as fast as you could hit the key and immediately get out on the ecns. The odd lot trades were filled electronically, instantly and didn't show up on the tape. As free as free money gets.
Obviously the specialist firms weren't fond of it.
