Are there programs you would like to see written or ported? Do any brokerages, data providers, or other services provide good support for we the few?

Why screw McCain-Bush (as if the two were related anyway)? The housing bubble, which is undoubtedly the cause of the economic downturn, came about because democrats on capital hill thought every American should be able to live the "American dream," and buy houses which they couldn't afford. They urged the major lenders to to get into sub-prime lending, which they wouldn't have done otherwise because it's terrible risk management. I believe many republicans were also in on this, so at best it's quite bipartisan.

You can blame a lot on Bush, including the terrible budgeting since that's an executive job, but the economy, not so much. Not unless you're a tool of Nancy Pelosi and Reid. I know it's popular around here to blame everything on Bush, but get the facts. Be enlightened.

Re:Hmmm (5, Insightful)

Anonymous Coward | more than 6 years ago | (#25064233)

Well, you have some facts skewed and some misplaced causality.

In 1999, Republicans wanted less regulation, causing investment banks to make create financial derivatives to hide risk and gain back their margins and bonuses, where normal banks could now compete.

Second of all, remember Bush touting the "Ownership Economy" where the sub-primes had artificially elevated the percentage of citizen's who lived in homes they owned?

Hardly sounds like a left-wing plot of the Democrats altering private banks attitude of lending via mind-control.

Less regulation, market forces, and human animus(greed, aggression, and fear), which if totally unchecked/balanced by other concerns can spell disaster.

Read this 2003 NY Times article [] about Republican efforts to increase regulation of Fannie Mae and Freddie Mac. There is plenty of blame to go around. Here's a little snippet from the article:
  Among the groups denouncing the proposal today were the National Association of Home Builders and Congressional Democrats who fear that tighter regulation of the companies could sharply reduce their commitment to financing low-income and affordable housing.

''These two entities -- Fannie Mae and Freddie Mac -- are not facing any kind of financial crisis,'' said Representative Barney Frank of Massachusetts, the ranking Democrat on the Financial Services Committee. ''The more people exaggerate these problems, the more pressure there is on these companies, the less we will see in terms of affordable housing.''

Representative Melvin L. Watt, Democrat of North Carolina, agreed.

''I don't see much other than a shell game going on here, moving something from one agency to another and in the process weakening the bargaining power of poorer families and their ability to get affordable housing,'' Mr. Watt said.
I'm not a proponent of either party - and so I think it makes it easier to see that they are both grossly incompetent for the most part.

They urged the major lenders to to get into sub-prime lending, which they wouldn't have done otherwise because it's terrible risk management.

So the major lenders are easily swayed by suggestion? Some how this doesn't sound quite right unless all the major lenders are managed by complete financial idiots. More likely, they saw lots of profits, and the White House (Mr. Clinton at the time) gave them a convenient excuse to exercise unbridled greed and usury.

The housing bubble was caused by the de-regulation of the mortgage markets that allowed mortgages to be divided up into little pieces and sold off in the stock market (mortgage-backed securities). In case you didn't know, McCain and Bush are big proponents of deregulation. You may be right (democrats want everyone to have a house and republicans want deregulation) and that's the formula that got us into this mess. As you said, a bipartisan effort made it happen. But you're not giving the republicans all the credit they deserve.

tacokill (531275) | more than 6 years ago | (#25064331)

Say what you want about the origins of the problem but there is no doubt whatsoever that regulation of securities (via the SEC) has been totally and 100% completely absent during all of this.

That, most definitely, happened on Bush's watch. The "laissez-faire" philosophy of the republicans sounds and looks a lot like Hoover right now. They have, literally, let Wall Street run itself. And you can see the end result on the front pages everyday. Whats the saying? Power corrupts and absolute power corrupts absolutely.

Look, I am no regulation lover but even the staunchest of conservative economists recognize free markets must have some regulation to insure a fair playing field. Under this administration -- there has been NONE.

Do you realize that many firms were allowed to leverage up 30 to 1? Let me break down what that means for the /. crowd. Say you have a $10 watch. You go to a pawn shop for a loan and they loan you what? I'd say about $5 or so. Certainly something less than the value of the watch, right? Well, on Wall Street lately, they've been getting $300 loans based on that $10 watch.

That is totally fucked up and should have never happened. End of story.

I never reply to AC's but I am making an exception.

Why? Because nobody in those posts is enforcing ANYTHING. And they haven't for a very long time. Yes, Congress makes the rules. But if nobody enforces them, are they really rules?

Re:Hmmm (4, Interesting)

Oswald (235719) | more than 6 years ago | (#25064453)

You need to inform yourself. First of all, the housing bubble was primarily fueled by errors on Wall Street, not Washington. The explosive growth of the mortgage-backed security industry created an environment that gave people lots of incentive to do really stupid things, like loan people money without requiring them to invest significantly in what they were purchasing or demonstrate that they had the money to pay back the loan. Secondly, here [] is just one of many available articles explaining that the really big hit has come from borrowers with good credit ratings and sufficient cash flow who simply do not wish to continue to pay the mortgage on a house that is no longer worth nearly what they paid for it. It turns out that you can default on your mortgage and all they can take is your house, not your other assets (who knew?).

Anyway, it's certainly not "authoritative," but here [] is a funny and true cartoon that does a pretty fair job of explaining how the screwed up incentives turned normal people in financial fuck-up machines.

Well, you're sure enlightened... (1)

Giant Electronic Bra (1229876) | more than 6 years ago | (#25064701)

Yeah, this will be an endless worthless flame war, but I'm sorry you are living in some kind of fantasy land man. The whole Republican Party is rotted to the core. Sure, once maybe it stood for something, now it is just the tool of those who are utterly unprincipled and for whom nothing is unthinkable. No lie is too base, no act unconscionable.

No politician in 21st century Amerika dares to cross the line of the Corpocrats who effectively run everything. Look where the money flows my friend, the 100 richest families in the US gained $670 BILLION DOLLARS in network in the last 7 years. If you cross them, they just edit you out of the news cycle friend. There's no end to the dirty money and no way you'll stay in office.

The real estate bubble was caused by the fact that Wall St in its infinite greed simply kept ratcheting up the leverage and lowering its lending standards until the lid popped off the whole house of cards (good mixed metaphore, eh). Where were all the regulators? Oh, I forgot, a 'free market' means we don't actually pay attention to those pesky LAWS anymore! Just buy them lunch and hire them for some cushy jobs when they retire and its no problem.

Doesn't help that your precious Republicans happily dismantled as much of that oversight as they possibly could. NOW the Corpocrats are using the Republicans to spend MY money to bail out their carelessly run (or looted) companies? Forget it. NEVER VOTE REPUBLICAN AGAIN AS LONG AS YOU LIVE. If John McAncient had 1/10th of the integrity he pretends to he wouldn't even be able to stomach calling himself one.

But don't worry, they won't have to pay, because they've already probably just ignored the last possible chance they had to even possibly avert an environmental catastrophe so vast that in a few years eating will be a luxury and nobody will even know what the word 'vote' means.

fishbowl (7759) | more than 6 years ago | (#25064505)

>Next time buy what you can afford.

Many did, and then saw the economy collapse around them, changing the nature of "what they can afford".

Some of these were unable to liquidate their real estate, because to do so would require them to literally pay a mortgage on the amount of money that the property declined by.

In my case, it has forced me to decline certain job opportunities because relocation is not an option, because of real estate values. (I would not seek, nor do I believe anyone will offer, a $45,000 relocation bonus to start, and that's what it would cost me to walk away from my home, never mind the fact that I like where I'm living and would prefer a *benefit*, not just a break-even proposition, for relocating.)

My story is not at all uncommon. I'm not bankrupt, but I'm at the threshold. And I have university degrees, more than a decade of experience, and the real estate in question is a modest property.

Web-based vs Desktop vs Palmtop (3, Interesting)

FraterNLST (922749) | more than 6 years ago | (#25063867)

I've started looking at this too as i've picked up some stock recently, and it is a difficult proposition (given that i'm not really willing to pay for a commercial solution).

Personally, I absolutely love the interface of Google's stock ticker - the interface is nice, the information is top notch. The problem being of course that there's way in any of the nine layers i'd trust google with my portfolio information. The big advantage of a local program in my mind is that the information you put in, even if it is only "I want to track these stocks" is kept wholly to yourself and not stored on some remote server where you have to trust the hoster not to take a peek.

In the end i've been using the default stock program that came on the iPhone to watch the stock prices. Thats all it will do, that and a short graph history, and it uses the yahoo info instead of the google, but it's close to realtime and it's stored (I hope) on the iPhone. Course, Yahoo can still see which stocks i'm requesting, so maybe in the end it makes no difference.

Ideal would be a device-based solution that could draw down the information, either from google/yahoo or direct from the *sx, and hold information regarding you portfolio too - but locally, so theres no worry of the monetary values being shunted across the net to the infovores.

Why would you trust -anyone- with your portfolio information? Has it become old-fashioned to believe that financial status and business is no-ones business but your own?

I have no idea what possible use Google (or anyone) could make out of knowing how much of which shares I own, what they're worth, and how much I'm up/down in the current market. There might be no advantage whatsoever they could make out of that information.

Personally, I'd rather not give them the chance to experiment and find out. That's just me, I like to keep my privacy regardless of whether or not it would hurt not to have it. Once you give it up, it's gone, and if you figure out it hurts later - too bad.

I don't understand. Why are you worrying if others know your positions? Especially if your just buying and holding (which admittedly you may not be). Think of it this way - you've already bought, maybe they'll say - Hey, that's a good idea, and buy it too, driving up the price for you.

Re:Web-based vs Desktop vs Palmtop (1)

FraterNLST (922749) | more than 6 years ago | (#25064695)

That's a good point, there isn't any real damage that could be done to me from knowing my positions in the market. Not with respect to the positions anyway. I haven't pissed off anyone enough that they would dump stock to hurt my position, and i'm nowhere near so deeply invested that something like that would work anyway ;)

It is still information that is considered private however. A lot of people don't like openly discussing their finances - but what bothers me more is knowing just how much information about me is out there. I have left a sizeable footprint over the years across the net and it's important to stop and think about just how much information you freely make available to people who are not necessarily going to tell you how they'll use it.

Doesn't it bother anyone else that there are these huge stores of information about them sitting out there, churning away, doing their best to find a way to make a profit from what they know?

If you've got buckets of money, NxCore ( [] - prices start at $500/month) and any of the brokers that support a FIX API (for which you can expect to pay a hefty fee, too; Interactive Brokers (IB - [] ) for example charge a one time $500 fee, OANDA ( [] ) charge $600 for the first two months then an ongoing subscription fee if you trade $12mil/month or something).

For those people not wanting to pour money into it, as good as you can get is Interactive Broker's Trader Workstation (TWS), and JBookTrader ( or a custom trading platform that talks to their API. TWS is a pain that lacks automated login (for security reasons) and auto-exits every 24 hours (for... err... security reasons?), but it gets the job done. Data feed can be an issue still, though; IB offer up to 100 symbols at a time, and a basic historical data service, but some people dislike the fact they drop price ticks during busy market times (over 10 prices per second) and the historical data service is paced so you can only do a limited of number of requests (about one every ten seconds I believe).

In short though, AC is right; use Windows, it may well be less painful. Really.

EclipseTrader [] is probably the most advanced open source trading program. It interfaces with some trading platforms and intra-day data feeds. It has several hundred technical indicators. It also is very expandable and easy to write modules for (in Java). I wrote some technical analysis modules for the back-testing system and was fairly impressed with how well it worked as it is based on the very solid OSGI/Eclipse model. I'd say it actually competes fairly well with some of the proprietary trading platforms I have used, especially if you are a Java coder and want to add modules to it to aid in implementing your particular trading style.

Re:EclipseTrader (4, Informative)

Anonymous Coward | more than 6 years ago | (#25064035)

Last time I tried EcT it consistently crashed on my Gentoo machine without warning, and it consumes unholy amounts of memory. I never trusted it enough to actually use it as a trading platform. For keeping an eye on your accounts and whatnot it's fine, but unless they've made heroic strides in the past five months, it's probably still unstable. And for that particular purpose I can use the excellent only Google interface.

The community around it is also rather thin, and (IMO) actually downright hostile to recommendations and bug reports.

Frankly, I'd rather trust being able to burst a sell order to an application that a company has spent a few millions developing and actively supports than to a "community project". So far I haven't had any problems with the former. Sure, I have to dual boot into Windows (no WINE for the one I use, at least not yet), but this is my livelyhood we're talking about.

Understandably there are some companies who are open source that turn a profit but your typical for-profit enterprise and their methods are the reason open source came into existence. You just know there is someone out there buying Microsoft stock on their Debian box via Ice Weasel....

There are some free terminals out there (1)

Giant Electronic Bra (1229876) | more than 6 years ago | (#25064509)

Specific places do offer terminals at very low prices. As to whether or not they would like it if you were running your own software instead of using their terminal, eh... Probably not.

Here's the problem. It takes a significant amount of net capital, not to mention you have to be a brokerage and a FINRA member, etc.

The market for "do-it-yourselfers" has to be incredibly small. Add in the fact they will be potentially high liability customers (heaven knows what sort of trading these people will do, but experience says they will mostly loose money big time). It doesn't really look like a very sustainable business model, nor even profitable enough for an existing firm to want to go after that market.

Technologically it is easy. I have a system that can easily do it, take in orders over FIX, sanitize them, do risk analysis, and route them either via a clearing firm system or DMA with a giveup in theory.

We have considered that the most likely possibility would be to form a coop and essentially just pool resources of small brokers and possibly individuals to provide the capital requirements and supply everyone with basic services like compliance reporting. Then it might be feasible, but don't hold your breath.

FINRA is TOTALLY corrupt. They're entirely controlled by a few big firms (and just that many fewer and bigger as of the last couple weeks). They're main function right now is to crush anything else. At best it is a real uphill battle.

Interactive Brokers's Java trading platform (TWS) (5, Informative)

Anonymous Coward | more than 6 years ago | (#25064167)

Interactive Brokers [] has a Java-based
Trader Workstation [] ("TWS") and they explicitly support Linux. They offer almost anything you can get anywhere, including mutual funds, stocks, options, futures (commodity & financial), currency, and foreign stocks. Commissions are 10x lower than Charles Schwab if you trade often (if you don't then a minimum monthly commission kicks in).

TWS is a large, cumbersome Java applet, but it works tolerably well on a fast machine (and there's not much alternative on Linux)

One annoyance is that they only support jdk 1.5.0_x (not the current 1.6.x), I think because of some concurrency bugs in their code (they claim the newer Java is buggy). However TWS generally does work with the latest jdk, but they won't support it.

IB's telephone support is sometimes rude, the opposite of "hand holding". I guess they have only a few over-worked support people to keep costs down. Also, they only provide on-line statements and never send physical mail except for annual 1099 tax forms. So, be sure your spouse/executor knows you have an IB account, because if you die there will be no monthly statements to clue them!

In summary, IB is good, despite their warts. If you trade a few times a month or more, it's worth the hassles.

Any trading platform is only as good as the data it gets.

Not to sound like an ass but anyone who is that serious about trading needs to invest in a Bloomberg terminal [] . If you are just dinking around - that's one thing. But the summary seems to indicate you are looking for a "serious" trading platform. Don't waste your time with FOSS. FOSS has it's place but a trading platform is not it. Go with a proven solution.

There are plenty of "active trader" platforms out there from a variety of brokers. Most that I have see are Java apps. I run Schwab's web-based active trading on Linux all the time but even it is a simplified version of the real thing.

Also, one more thing to consider: I would hate to find out that my FOSS trading platform had a bug. If it's bad enough, it could be devastating and totally wipe you out. Do you really want to take on that kind of risk? This really isn't the place to be "testing" your trading platform when real dollars are at stake.

Now....analysis is a different beast. FOSS might have a place there. I don't know but I see no reason to reinvent the wheel when there are FAR better solutions already out there. I have yet to see anything from FOSS that is compelling. And no -- MS Money/Quicken imitators are NOT what we are talking about here. Not even close.

As far as being able to use a FOSS platform, Reuters provides data/infrastructure software that is specifically geared toward *nix use, including C++ and Java APIs, however, most of it is enterprise level and typically outside of the scope of the individual user. If you're running a moderate to large scale firm full of day traders, it would be the way to go, if not, I'm sure something like E-Trade (ugh) would work just fine in Firefox.

I personally know a hedge fund manager who does fixed-income arbitrage. They manage billions of dollars and thrive on volatility. Their trading platform is windows-based, however, and to keep such critical systems running smoothly, they have to pay a lot of people to monitor it constantly. The reason more high-end firms don't use FOSS is due to the fact that all the top trading software out there is proprietary, custom, and Windows-based. Here's a profitable area that enjoys both economies of scale/scope and high barriers to entry. The first people to get in this market stand to make a lot of money.

That is the trading system I've spent several years working on is built entirely using Open Source tools and libraries. The system itself is not currently open, but that is a possibility we here certainly look favorably at.

As far as actual entire free trading systems, there is which is a good place to start. Also check out the site, you will find some things there. There is also an Eclipse plugin which provides some level of GUI.

Frankly we didn't any of the code in any of those projects (although we do use ta-lib). But as I say, you can do a lot with ActiveMQ, any good open source RDBMS (PostgreSQL,MySQL) and your Enterprise Java framework bits of choice.

Basically if I were you I'd pick one of the java based projects that is kicking and does roughly what you want, the way you want to do it. For simple basic trading of one or two instrument classes you can probably put together something pretty workable.

In terms of commercial entities, many of the big banks have some Linux, and the biggest Wall Street firms have huge footprints (tens of thousands of Linux servers). At that scale, it's mostly Linux or mainframe, with some older non-Linux Unix gear hanging around.

Wall Street was one of the first sections of the corporate world to really dive into Linux (to get x86 with a Unix-like feel) and helped push the industry maturity along.

In terms of prosumer-grade stuff, any of the raw math libraries you'd want are going to be available on Linux, as will most higher-level analytics, but probably not at the price point you want. GUI stuff? Probably not.

Resources of Linux/Java trading software... (2, Informative)

wintermute42 (710554) | more than 6 years ago | (#25064651)

I have not seen any open source projects that you can use as a platform for building a trading system.

I have built an intraday (within one day) trading system in Java. I'm afraid that this system is not open source either. This system runs one or more models that look for intraday trading signals. The Java software submits buy and sell orders. It is multi-threaded and runs one thread per stock. I have been very happy with the software performance. A long running "server" like this seems to benefit from Sun's HotSpot compiler. The system is web services based (e.g., it runs on Tomcat).

I used Interactive Brokers [] for my market data and order infrastructure. I was concerned about the quality of the Interactive Brokers tick data (the trade by trade data). Interactive Brokers consolidates their tick data feed so you get a consolidated tick about ever 250 msec. For my system this has been adequate. If you want to run on Linux or use Java there are few inexpensive options for real time data feeds. Information may way to be free, but market data is expensive.

I have some web pages on the alternatives that I explored as platforms for a Java/Linux based trading system. These notes can be found on my web page Software for Constructing a Market Trading System []

I'm pretty much got sucked in the same way. My solution was to write all of my own analysis tools. I've thought many times about open sourcing the goods. I've got 10 years of development into a data warehouse analysis system that pushes the limits of what PostgreSQL will do on modern hardware. The only way to ensure privacy of your analysis and back testing is to run your own data warehouse. I can only imagine the kinds of customer data that is skimmed from stock analysis/filtering "services". In my opinion, it's only worth doing if you can get a view of the whole market. Feeds of just a few stocks is incomplete when you're trying to marry trends of market to sector to individual stock. Finding a good data source can be quite a challenge if you don't have thousands a month to spend. But, it can be done with some compromises. Since I started developing analysis tools, probably the best alternative I've found out there is called quantlib and is C++ centric. If you know of a portfolio manager looking for a risk analysis computer geek then let me know. ;D Or if anyone is serious about getting more serious about financial FOSS and/or SaaS, let me know.

some thoughts (1)

Anonu (233018) | more than 6 years ago | (#25064665)

i work on a quantitative trading desk at one of the big investment banks and i get quite a unique opportunity to straddle both the tech world and the finance world. most trading and risk mgmt systems are built using Java or C++ in linux environments...

in my world I rely heavily on perl and python. R or Matlab are good tools for doing regressions. R is FOSS. Matlab is not so we end up paying for a few licenses. In return you get good customer service, regular updates and a nice set of toolboxes for doing things like GARCH, etc..

Now you gotta ask yourself what sort of trading are you going to be doing? Are you looking at day-trading? This entails looking at market order books - bid/ask quotes and trades and working with large datasets. At this pt you may want to start thinking about optimizing your calculations and managing memory. A full days worth of quotes in today's market can be up to 60GB uncompressed (obviously this depends heavily on the formatting, etc... - but thats sorta what you have to deal with). You're better off writing optimized routines in something fast like C++. Pushing that much data through R or Matlab will grind those tools down to a halt.

Getting your hands on "tick" data is not too cheap if you're an individual. You can look up TAQ data on the NYSE website. They charge about $1000/month for access to their tick data.

If you're looking at investing (rather than just trading) on a longer time-horizon. Then you're going to need fundamental data. There are plenty of companies that charge hedge funds, etc millions of dollars a year for this type of data - companies like Bloomberg, Factset, Barra, etc... The thing is most fundamental data is freely available in regularly filed reports with the SEC - like 10Ks and !0Qs. What you are paying for is getting this data in 1 place and ensuring its quality which is crucial.

technical analysis FOSS (0)

Anonymous Coward | more than 6 years ago | (#25064685)

If you don't want to daytrade, realtime data subscription isn't that important. For short term trading (in a week span) and, of course, longer term trading, free data from Yahoo is enough (about 15 minutes of delay. Google provides NYSE in real time, but not in csv like Yahoo, so it isn't as useful as Yahoo data). There are several FOSS options for technical analysis based on free data. My choice is Qtstalker. It has tons of indicators, a simple script language for rule testing and stock search and a very simple portfolio manager. Some people prefer something fancier, but one of the best advices I've heard about technical analysis is to keep it simple and work with a reduced number of indicators in order to avoid conflicting results (cf. Alexander Elder about that). Another nice technical analysis FOSS is AIOtrade. Looks pretier than Qtstalker and has an interface for "real time" data possibly customizable for receiving paid input. But it seems to me less flexible than the last versions of Qtstalker.
Another interesting software is Merchant of Venice. It is ugly, has fewer indicator than Qtstalker, but, on the other hand, it has interesting features as genetic algorithms for refining trade rules, neural networks etc. I wouldn't use it as my main analysis platform, but these features may give good advices.

Good luck!
