Quote from surfrider:
dump routing means the market makers in the brokerage houses can trace/keeptrack of your orders now and really move a stock contrary to trading sentiment-even though sentiment is aligned with market!
This is something I have suspected for quite a long time now, as this happens to me on about 90% of my trades. The market immediately moves against you and even when it starts to return to your entry position, most of the time it stops exactly at your entry point and will either bounce or stay there, denying you a profit. This happens to the penny, even if the position was entered through more than one trade.
Other than my broker giving them information about my account position, or identifying some type of account reference when they place the order to their order routing buddies, I can't figure out how they know my position and can affect the entire market, just to get to my lousy 500 share position in a multi-million shares/day stock?
