Citadel KCG HFT hedge fund investigated
The time has come
Small, day-trading investors make up the majority of the customers of mass-market brokerage firms such as TD Ameritrade, Charles Schwab and E*Trade. These firms sell their stream of stock-trading orders to market makers such as Citadel and KCG.
This appears to be living proof these crap brokers are selling their order flow (of paying customers) to these firms to allow them to take advantage of your orders.
