Yup, mostly because of the inefficient bureaucracy here. It was the same when I was in Sao Paulo; I had to talk to the chief manager and explain to them how a VISA online transaction using a passport and VISA card worked. Roughly 90 minutes of elaborations, phone calls and "research" within the...

I ended up not doing a single trade during the RTH; I got bored and went to the bank to make some transfers (which is 2 hours of paperwork etc). The 28-day national bank strike ended 2 business days ago, so now it's possible to use the banks here in Brazil again. Fair warning to anyone doing...

Just that it is speculation in the US press, and coincidentally large selling on tradesports.com against Bush's recent gains in poll. Also, if Kerry starts to mention a fading international support for the USD, then we'll know it's a "coordinated attack". Hilarious stuff. Probably some...

Just watching the crawl higher since I can't really see a good, clear entry. As a position trader I might have gambled before the numbers, or tried the bounce earlier (the 1.2460 support), but would have to get up 5 mins earlier in the morning for that bounce. :) Hehe, Thomson mentions...

I use neural-networking, Bayesian networks, Hidden Markov Models (self-organizing maps), Prolog-type rules and a whole lot of other stuff to try and get those patterns identified. It's still dependent on getting some "aggregated, clalculated data" right as the input ... which is what I'm doing...

Yes, I called it "time-zones" but only because they're time-limited; i.e they end fairly quickly. When the zone ends, it doesn't mean that I end the trade - just that I can't do an entry again. So then I REALLY watch my profits and will be VERY conservative about letting profits wane. I...

Overtrading will stab you in the back always; it's the worst of all sins to me. It either will run your losses like crazy, or make you a sorry "winner" with all the commission. Try identifying "time-zones" when trading is safe - and learn: what are the signs of transitions into other...

I'm not that familiar with recent versions - as I've only used years and years back, but I still get the impression that mySQL is faster on simple databases and simple operations than PostgreSQL, which has some more advanced features. I guess the licenses also determines usage a lot. Two great...

Isn't mySQL fairly simplistic in comparison to the also free PostgreSQL ? I remember mySQL being more used for small tasks and web-oriented deployment. Also, the licensing of mySQL requires that you stay away from commercial deployment, while PostgreSQL uses Berkley license ? Also, mySQL only...

Seems like a lot of "micro-chopping" right now - a lot of trading - similar to yesterday after the rise; and tug-of-war on every single tick it seems. Uncertainty in the markets because of no strong sustained trending, I believe. Remembering it's friday again, I will be very conservative about...

I overslept, and only got to trading around 09:15 EST. Two shorts and one long trade all for 10 ticks profits ... I was a little sleepy and didn't even realize the Michigan Consumer Confidence was upon me on the second short, before seeing the orderbook was almost blank. I really enjoy this...

Another tip for anyone interested: When I first started designing my charting etc. I wanted transparent indicators so that at least some (2-3) of them could be overlapping or stacked on top of each other. The problem I found was that I were using BeanShell scripts which were quite slow (many...

You're so right! I forgot to mention that I always think about tick-data and products like ES, EuroFX etc., but of course 1-min, 5-min or larger OHLC-data will not be so much of a challenge. Good point. :) OTOH, if you talk 20k symbols or something, you're getting back in there .. just like...

Sure, IBM DB2 Universal Server and data-mining addons are well suited e.g. Proper backups and storage are of course the same responsible attitude required for all types of IT work - regardless of StorageWorks libs, tape-robots, CD-RW, whatever. :) I think this is the preferred way for all...

I think they mostly go for positions and stay in them until they hit either a stop or a target - although they adapt targets somewhat - like the "go flat on 1.2420 failure" - kind of vague. If you remember they also show a list of support, resistance levels and commented strategies on...

The chop is very much in for some splatter, although volumes are bleak. Hey, it just rammed it down a little to 1.2382-ish. Well, just the same as the little higher constrained range we saw earlier. Running stops now and applying the hatchet. Trying to guess where the range and hatchets will...

I strongly believe you actually mean that you would hold any data you would test or manipulate - in memory - and NOT on file or database for individual record updates (yuck!!). So the manipulation bit get's fairly equal, while the storage part is different. Well, that is if you don't need...

Thanks, seems like Thomson also descibes the market as slowly creeping upwards and frustrating the traders (I guess the overtrading signs I saw) with soft volumes and central banks limiting breakouts on both sides (I guess they mean over the medium term - not esp. today) and the trading range...

Have you thought about moving the indicators into scripted versions, or at least having capability of adding new indicators with scripts ? That would save you a lot of re-working, if you have an easy API for doing the indicators from scripts. I use the Groovy script language now, but used...

Couldn't resist a quite safe short from there, and now I'm definitely stopping, with 36 tick profits now, on 7 trades. edit: seems QM and 6E are still a little pegged, but I don't see them doing any big moves together. Choppy doldrums are already here.
