Hi. I was wondering whether there are any legal issues wrt using historical quote data to generate content for a commercial web site. For example, if I wanted to generate charts and display historical data points and make people pay for access, is it necessary to get permission from nyse/nasdaq...

https://www.tdameritrade.com/api.page There's an email address on that page to ask for access. As I recall they just give you a 2-digit code to embed in API requests, access to a forum, etc. I don't think it's 'secret', but I suspect there isn't as high a demand since they're paid for order...

I think the only time I'd want someone tailing my trade is in a pump&dump situation and the followup trades can help push up the price and/or generate enough volume for me to sell into. In cases where I have real edge, I think having anyone else on my side of the trade, especially people who are...

Not to say that it would be impossible, but I think it would be very unlikely that a broker would be copying or paying any attention to your trades in a small-cap low volume stock. I think Etrade/IB are way too large and regulated.. I wouldn't think an employee would be able to arbitrarily...

Well, Virtu was aiming for a $3B valuation before the IPO got sidetracked. Anyway, I think without the Lewis book, IEX probably isn't as successful and SEC enforcement would probably still be in a much lower gear.. and I think many exchanges already rolled back some HFT-friendly order types and...

If your profitability estimates are correct, wouldn't it make more sense just to hire people to develop strategies full-time, or spend more of your own time developing strategies, until it became much harder? I can't imagine training a few guys with no background for 2 weeks would yield better...

Maybe ET can set up a mentorship matching system. It could work like angieslist/taskrabbit or something like that. Potential mentors can advertise what services they would provide, track record, fees, types of students desired, etc. Mentors would be required to provide evidence of their track...

I think it might depend on the type of trading strategy as well. If I were a mentor, I don't think I would teach anything that the student could just walk off with. Trust would be a big part of the equation since the mentor is paying an up-front cost and hoping the student ends up being a good...

I think the trading education industry is structured the way it is because of the economics of trading. I would think that the money flow would resemble a pyramid, where lots of guys on the bottom are net losers and a small number of traders at the very top are making a killing. I'd guess that...

I think that cost is what IEX charges your broker, but not what your broker charges you. For Tradestation: http://www.tradestation.com/en/pricing/stocks-and-etf-pricing They don't charge extra for per share pricing, but for flat-fee pricing: "Direct routing up to 1000 shares is no additional...

Since you mentioned that only 20% of your algo strategies would even be profitable on a retail platform, it seems like a catch-22 for retail traders. For traders who are interested in ATS development, even smart ones who are dedicated and have lots of time to devote but doesn't have a brother...

Thanks for the insightful posts on this thread. Considering most people on this site are retail traders, I was wondering what your gut feel is on algo trading for typical retail traders who trade through a broker such as IB. Earlier on in the thread you emphasized the value of...

My gut is telling me that saying "trading can be learnt" is trivializing it a bit especially when you're equating it with learning how to code. I don't quite think it's learn-able in the same way as learning to code, which probably just comes down to time/effort/practice. In trading, there's no...

I think there's a big difference between writing commercial quality code at a real software development shop as opposed to writing something for your own personal use which no one else will ever need to look at it. Assuming you're a discretionary trader with a profitable strategy, I'd think you...

OP == self-entitled jerks

90% of them are too busy pumping their own crap to pay attention to yours.

The lag should be due to the fact that you're sending keystrokes across the net, not the configuration of the VPS. I don't think using a VPS as a desktop is the proper use. Save it for server-type applications.

Maybe too many intelligent folks in chat? I think imbeciles are the ones that care about other people's "calls".

Why would you be watching a youtube video on a VPS? I don't think watching videos via a remote desktop is ever going to cut it (if that's what you're doing). Lag is probably from network, not your OS, although 2GB seems like it's on the low side for Windows Server.

Yup, a rising tide lifts all boats. We're in a 5-year long bull market so take all advice, testimonials, account statements with a grain of salt. Agree with the arbitrage vs punting thing too.
