Which brokerages offer the best streaming quotes (tick level) for the best price?
I have ScottradeElite on my desktop. I have played around with it but no longer use it. The transactions that I make through Scottrade are more dependent on my goals for the securities than what the market is doing at the moment.  Keep in mind that there will always be others out there with better access to price changes than you. They also will have better hardware. We cannot beat them at their game.
"This is the best tl;dr I could make, [original](https://americanaffairsjournal.org/2017/05/new-class-war/) reduced by 99%. (I'm a bot) ***** &gt; In the United States the majority of American college students come from the minority of families in which one or both parents have college degrees.  &gt; The incompatibility of the welfare state and mass immigration was noted by the libertarian economist Milton Friedman: &amp;quot;If you have a welfare state, if you have a state in which every resident is promised a certain minimum level of income, or a minimum level of subsistence, regardless of whether he works or not, produces it or not. Then really is an impossible thing.&amp;quot; His ideological opposite, Paul Krugman, agrees.  &gt; It will make no sense for the United States to tolerate similar mercantilist trade policies at the expense of American industries, particularly those relevant to defense, carried out by China-the only &amp;quot;Peer competitor&amp;quot; the United States will face in the foreseeable future in the military realm.   ***** [**Extended Summary**](http://np.reddit.com/r/autotldr/comments/6ejbil/the_new_class_war/) | [FAQ](http://np.reddit.com/r/autotldr/comments/31b9fm/faq_autotldr_bot/ ""Version 1.65, ~133514 tl;drs so far."") | [Theory](http://np.reddit.com/r/autotldr/comments/31bfht/theory_autotldr_concept/) | [Feedback](http://np.reddit.com/message/compose?to=%23autotldr ""PM's and comments are monitored, constructive feedback is welcome."") | *Top* *keywords*: **State**^#1 **market**^#2 **work**^#3 **managerial**^#4 **new**^#5" "A couple options that I know of: Interactive Brokers offers a ""paper trading"" mode to its account holders that allows you to start with a pretend stack of money and place simulated trades to test trading ideas. They also provide an API that allows you to interface with their platform programmatically for retrieving quotes, placing orders, and the such. As you noted, however, it's not free; you must hold a funded brokerage account in order to qualify for access to their platform. In order to maintain an account, there are minimums for required equity and monthly activity (measured in dollars that you spend on commissions), so you won't get access to their platform without having a decent amount of skin in the game. IB's native API is Java-based; IbPy is an unofficial wrapper that makes the interface available in Python. I've not used IB at all myself, but I've heard good things about their API and its accessibility via IbPy. Edit: IB now supports Python natively via their published API, so using IbPy is no longer needed, unless you wish to use Python 2.x. The officially supported API is based on Python 3. TD Ameritrade also offers an API that is usable by its brokerage clients. They do not offer any such ""paper trading"" mode, so you would need to ""execute"" transactions based on quotes at the corresponding trade times and then keep track of your simulated account history yourself. The API supports quote retrieval, price history, and trade execution, among other functions. TDA might be more attractive than IB if you're looking for a low-cost link into market data, as I believe their minimum-equity levels are lower. To get access, you'll need to sign up for an API developer account, which I believe requires an NDA. I don't believe there is an official Python implementation of the API, but if you're a capable Python writer, you shouldn't have trouble hooking up to the published interfaces. Some caveats: as when doing any strategy backtesting, you'll want to be sure to be pessimistic when doing so, so your optimism doesn't make your trades look more successful than they would be in the real world. At a minimum, you'll want to ensure that your simulations transact at the posted bid/ask prices, not necessarily the last trade's price, as well as any commissions and fees associated with the trade. A more robust scheme would also take into account the depth of the order book (also known as level 2 quotes), which can cause additional slippage in the prices at which you buy/sell your security. An even more robust scheme would take into account the potential latency of trade execution, looking at all prices over some time period that covers the maximum expected latency and simulating the trade at the worst-possible price." A company is basically divided into shit the company owns (assets) and shit the company owes to people (liabilities). So what about ownership? Ownership is called equity and on a simplistic level equity = asset - liabilities. But a better view of that should be asset = liabilities + equity. Which means a company's assets  is separated into things owned by debtors (e.g. Banks) and things owned by owners(founders and you). So when you are offered one percent, you are basically owning one percent of the company.   Not the best explanation, but should be a simplified one.   Here's where the options come in. When you are offered options. That means you have the option of redeeming the shares at a lower price than market. However these options are not usually immediately redeemable, there's usually a minimum amount of time you have to work at a company to be able to use these options. This period is called the vesting period.

"I'm familiar with and have traded U.S.-listed LEAPS and I've always used the CBOE quotes page you linked to.  So, I too was surprised I couldn't find 3M (MMM) LEAPS quotes at that page, even after checking the ""List all options, LEAPS, Credit Options & Weeklys if avail."" radio button.  Used to work! Fortunately, I was able to get access to the full chain of option quotes from the CBOE's other quotes page:  Go to the ""Quotes & Data"" menu, then select Delayed Quotes - NEW!  Here's how: I think the new interface is terrible: it's too many steps to get to the information desired.  I preferred the all-in-one table of the Delayed Quotes Classic page, the one you linked to. As to why that classic page isn't yielding the full chain, I can only suggest it is a recently introduced bug (software defect).  I certainly was able to get LEAPS quotes from that page before. On Yahoo! Finance option quotes: I don't know why their chain is incomplete – I can't see the logic, for instance, as to why MMM Jan 2012 60 calls are missing.  I thought at first it may be lack of volume or open interest, but nope.  Anyway, I don't trust Yahoo! to provide accurate, reliable quotes anyway, having seen too many errors and missing data in particular in the feed of Canadian stocks, which I also trade. I rely on the exchange's quotes, and my broker's real-time quotes.  I check Yahoo! only for convenience sake, and when it actually matters I go to the other more reliable sources. For what it's worth, though, you can also get full chain option quotes at NASDAQ.  See here for the 3M (MMM) example then click on the ""Jan 12"" link near the top.  However, I would consider CBOE's quotes more definitive, since they are the options exchange." I think your best bet would be commission-free ETFs, which have no minimum and many have a share price under $100. Most online brokerages have these now, e.g. Vanguard, Fidelity, etc. Just have to watch out for any non-trading fees brokerages may charge with a low balance. "This is called ""change"" or ""movement"" - the change (in points or percentage) from the last closing value. You can read more about the ticker tape on Investopedia, the format you're referring to comes from there." I had the same problem and was looking for a software that would give me easy access to historical financial statements of a company, preferably in a chart. So that I could easily compare earnings per share or other data between competitors. Have a look at Stockdance this might be what you are looking for.  Reuters Terminal is way out of my league (price and complexity) and Yahoo and Google Finance just don't offer the features I want, especially on financials. Stockdance offers a sort of stock selection check list on which you can define your own criterion’s. Hence it makes no investment suggestions but let's you implement your own investing strategy.
