Quote from kapama:
I guess I am all confused because of the fact that some old experienced trader telling me about slippage. You know what I mean.
He specifically said they monitored several borkerages' level II system and observed that all prices were different and after researhing for sometime they figured afew of them are giving real prices some of them which are terranova and tradestation and Fidelity and such.
Didn't you guys hear about how BofA and other brokerages paid millions of dollars because of manipulating prices. Either he is lying to me or
I don't know.
Howcome zecco.com is making money then? Trading is free and even the unlimited shares are free. Isn't that fishy? Go figure.
What are we missing here?
Alas, SEC don't do anything.
I doubt it's a conspiracy. Some LII quote providers are faster than others. Get the fastest data possible. Also, some might not show all ecns. So the issue is not seeing all ECNs and having laggy data.
