attributed to Keynes, and sage advice for those trying to call tops/bottoms: "The market can stay irrational longer than you can stay solvent." Calling a top way too early and acting upon that call is at least as bad as noticing the correction too late. Greenspan's irrational exuberance...

forex-forex>I'm surprised that Germany would go with the EUR over their own currency. Consider General Motors building cars in Detroit and selling them in Chicago. Imagine if Illinois & Michigan each had their own separate currencies. If so, then for each car that GM sold in Chicago, they'd...

Uhm, try google'ing for: SEC PDT NASD and you'll see: http://www.greencompany.com/EducationCenter/GTTRecTraTypPDT.shtml So, the definition of PDT comes from the SEC, but the PDT $25K rule is purely NASD. NASD is an SRO covering securities in the U.S. Securities = stocks, bonds, & some...

Billbuild>Bloomberg is kind of a corporate shill IMO. To suggest someone is generally a shill for corporations is to suggest that all corporations have a vested interest in the same outcomes. Perhaps it might be reasonable to suggest that institutional fixed income traders and institutional...

NickelScalper>Good point regarding renovation adding to the longevity of a house. Indeed, at what point does it become "new construction" disguised? The quantitative answer to your question might possibly be suggested by the JCHS annual SON report: Table A-2 Housing Market Indicators...

Billbuild>We just tore 1 down about 2-1/2 yrs ago. Built in 1890. .... Today's house could be better built, but it is so far superior to what was being built here 100 yrs ago on average. I hear what you are saying and agree, but put it in some context. That house you tore down did in fact...

yenzen>Nah, they'll invent a 50 year mortgage after prices hit 400k In addition to mortgages with amortization schedules longer than most people could reside in the dwelling, one alternative used in some parts of Europe (i.e. London) is to separate RE transactions into: sale of freehold...

kc11415>>1) Is your timing of this query fresh after the database is started? marist89>Give me a little credit. Please accept my apologies. I was just curious ;-) _______________________________________________ linuxtrader>As far as answering a laundry list of inquiries about...

marist89>...I can get 850K records out of my database of 500M records in less then a second. Of course, I run Oracle. That sounds rather good. May I ask: 1) Is your timing of this query fresh after the database is started? Or, is it after some of these 850K rows have had time to be...

kc11415>... This would require calculating 250,000 time-series correlations ... Very few institutionals will invest what is required for a strict calculation of beta. billgates>250K * 252 days * 10 years ~= 1B arithmetical operations. My $60 Celeron will do it in few seconds. Any...

Sparohok>Sure, every application is different, etc. But I think there is a right way to handle large amounts of time series data, and that is to keep it in a true transactional database and then cache as necessary for performance. I think this depends upon your definition of "time series...

inflector > Even a 10,000 RPM disk takes 6 milliseconds to rotate. So you only get 167 rotations per second. That's a lot of time when computers are doing billions of instructions per second. This is very big factor in random access to a block here and a block there, such as in OLTP. While...

I've run many gigs of ticker data within big multi-cpu Unix servers with many gigs of RAM and hundreds of gigs of fiber-channel disks organized as RAID arrays. I have also used awk & Perl on a laptop against gigs of tick data stored in simple text files. Depending upon the question to be...

Ah, OK. Those do seem to be rather severe bugs. With the inability to grab just a subset of the data, then does that mean it's and all or nothing deal? i.e. if you pull any data then you have to pull it all? For instance, if I were willing to download the entire history of a time series...

OK, you've described the "severity" of the problems in terms of its impact to you, and how eSignal might "workaround" the problems. Could I ask you to describe the nature of these deficiencies? i.e. how does the problem manifest itself? Many years ago, I had a CS professor who said that...

EdgeHunter>esignal recognizes this field ... - but this API is not ready for prime time… and is still struggling on its first design legs… This sounds interesting. How severe is the "not ready for prime time" situation? i.e. could you get enough usability out of it if you were willing...

May/June 2004 issue of Futures Industry Magazine "A New Day for Kofex" http://www.futuresindustry.org/fimagazi-1929.asp?a=920 The stats show that foreign participation in these contracts is growing, while Korean domestic retail participation is cooling.

Let me see if I (a newbie) understand this correctly? In comparing the differences between going with a prop shop vs. using a direct access retail broker from home, there are some resources those desk fees are paying for, which might be self-resourced by a trader at home for the same or less...

LAZYBONES> We will call my friend, Jim. He's and active futures trader and has been making a living doing it for many years, and did well as a local. He looks like an old investor, "his looks are deceiving". He shows up to a lot of free seminars with his costume...an AM radio in his pocket with...

Over some number of months I've seen a variety of criticism of Jai, some less than constructive, and some of which is just healthy skepticism. I wasn't certain the main themes of his presentation would be directly applicable for my interests, but I wondered if any reading-between-the-lines or...
