Spreads are much narrower than they used to be, but of course they'll still be wider in thinly traded or risky instruments.
Many places offer portfolio margin for a $1M account, generally giving margin significantly better than 4:1. Most offer multiple platforms, and...
Agreed. But unlike "other skilled trades", even after 10,000 hours, my guess is that a new trader will still almost certainly fail -- unless...
I never saw a subpenny fill on BATS when I used it, but then again I switched back to Nasdaq for almost 100% of my trades as it seems I get better...
That's bizarre. Did it really go to BATS? Or did your broker internalize it? Try calling your broker or BATS and ask the question you just...
I think this is a phony email. The actual bill is even more bizarre (it's for a 1% tax on all transactions, including stock -- plus the...
Only DirectEdge has flash, right? NSDQ and BATS got rid of them as of Sept 2009 -- at least that was the latest news I saw. So if that's still...
NSDQ starts quoting/matching as early as 7am. ARCA starts quoting as early as 4am, but what constitutes "open" for you, you'll have to decide...

I've seen your posts in other threads, saying similar things about other types of traders. So in your book, everyone who trades is "scum"? Or...
I think NxCore has very good data, if you are willing to use their API, which is the same used by their live service. It may be cheaper and more...
So James Simmonds and D.E. Shaw are going to end up working with you for $10/hour (if you can even afford to pay that much)? :D
That's a pretty long list -- what, may I ask, is the broker you're using? And are all those available to you now, or upon request? I think...
In addition to significant profit drops in Goldman's equity unit and Timber Hill (IB's market making division, which used to make most of IB's...
The Automated Trading section has quite a bit on this. Also, there are "quant" sites such as nuclearphynance.com and wilmott.com that have a...
Interesting post; thanks, Paul -- makes me appreciate the difficulty of this problem.
