AUTO is : Automated Trading Desk Financial Services and ATDB is : Automated Trading Desk Brokerage Services. Both are located at 11e Wall St., Mt. Pleasant S.C. Now that we know we are dealing with a company, rather than a trader
All MMs are companies. They sometime trade on there own but most of the times they are representing traders like you and me. I use Scottrade so most of my orders go through NITE but sometimes they are routed through AUTO.
I stand by my opinion that there is no MM manipulation here. Auto is representing some one retail.
