Some of us are lucky enough have a father who spent 40 years in the business. One day, he sits you down by the fireplace, pours you a snifter of brandy and says, "Son, it's about time you learned how to profit in the market. Here is how I made my first million." This is not me, and it doesn't...

Heya Peeps, I'm looking for an "affordable" and online version of this course, and/or a book: https://www.sps.nyu.edu/professional-pathways/courses/FINA1-CE9000-introduction-to-the-markets.html Any recommendations? Thank you. Sincerely, Keith :^)

We used to call this a "screen scrape." Note that writing to the screen is an expensive operation (in terms of time). It will reduce your speed by a factor of at least 10.

..and viable technical/other alternatives. As for legal alternatives? L O L, What are you going to do, sue the exchanges? :rolleyes: Write a letter to the SEC? They approved this in 2015; they're on payroll. We are all at their mercy. I've been noodling on this for months and months. The only...

Stepping out of the details for a moment, what really annoys me is how all this paywalling limits innovation, and creates advantages for those who have the ca$h. It's not just market data. It's book data: Level 1, level 2, level 3, 4, 5, and up--if you think that the numbers on your screen...

+1. At a minimum, this would put you on a blacklist.

Peeps, I have to say again, thanks for your feedback. I have been much more careful with my trades today. I've only reversed four. They've all been profitable, and I'm happy with my subsequent position. :thumbsup: Looking back, I think that I was just over-trading out of frustration. How do...

I still don't see the task as enormous. They'll probably push it to the broker-dealers and their terminals. If they don't want to play ball, they might fall onto the "unapproved." list. It's really just the following bit of (pseudo)code, right? On program launch, send the program's hash value...

My guess is that you'd have to sign off on this before your algo can be run. I don't think that it would be terribly difficult. Just write it in C++ or some other portable language, and recompile on the major platforms. Yes, some effort, but not "enormous." The task is not really that complex...

I know brother, it's aggravating. Terr and I are saying the same thing in different ways. You have to version your code, and submit this version for approval. The Man approves this version, and only this version one can be run. If you so much as change a letter in a comment, recompile, and run...

I was told that there is some kind of entitlement system either in place or being put in place, where only an authorized version of an algorithm is permitted to consume the data. You may have to run their monitoring process on your box... and run as r00t. Full cavity search, my friend. In some...

Good luck with that. The best answer I've found so far is: FOREX. That's the unregulated venue. The only problem is that Forex, is, well, forex.

Joan, there is an interest at work here. The exchanges want iron control of their data and how it is used. Here's is the business model, as it was explained to me by a major data vendor: It's the old "seat at the exchange" model. Every chair has one terminal, whether it be Bloomberg, Reuters...

Nope. You're playing games... and you won't wiggle out of it that way.

I was so aggravated by all this that I actually started building a new exchange, a "lit" pool, where data in all its forms--market, deep book (Level 2,3,4,...n), and queue data alike--are all free. A level playing field, where we can openly develop and run algos, without all this non-display...

I never said that I was sure!!! I'm not a lawyer, and don't work for IB. I'm just relaying what I've been told, and giving my opinion on the matter. I use TWS and the API; specifically, the C++ version. http://interactivebrokers.github.io/tws-api/#gsc.tab=0

(Raises Hand). I was going to buy a data feed, and looked at a few vendors, but was stopped cold by these non-display fees. Let's not forget that there's more fees from the vendor for the data, including setup and monthly fees. It's just too expensive. IB's data feed is usable, but I had to...

Yes, you are correct. I slept on it, thought about it all night, and that was my big lesson learned. I was over-trading; trying too hard to get on the right side of a swing. Those who said that I would learn from this were right. Thank you. Already today, I'm being more careful and selective...

IB's data are a volume-weighted average, and that is not real-time tick data. Since non-display fees only apply to real-time tick data, and IB do not supply a real-time data feed, non-display fees do not apply to them or their customers. If you call and ask, they will tell you, "We are not a...

Note that IB do not provide real-time tick data. Their data are a (slightly) delayed volume-weighted average, and so real-time non-display data feed fees would not apply.
