You cannot be serious?
TH said:For more than twenty years, Simons' Renaissance Technologies hedge fund, which trades in markets around the world, has employed complex mathematical models to analyze and execute trades, many of them automated. Renaissance uses computer-based models to predict price changes in easily-traded financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions.[7] Some also attribute Renaissance performance to employing Financial signal processing techniques such as pattern recognition.

Renaissance Technologies LLC, a hedge-fund heavyweight, has been bruised in the market's recent turbulence.
Two of the three hedge funds that the company makes available to outside investors have suffered sizable losses this month, largely due to the big drop in the Japanese yen, investors say.
At the same time, Renaissance continues to raise cash at a slower pace than some had expected. The firm manages about $6 billion of cash for outside investors—down from about $25 billion in 2007.
Do you like trading? If no, stop trading. You're done.
If yes, then it's no big ask to practice stuff. Stopped out for today? Or the market is bad for how you trade? Hopped on early? JUST STARTING? Then hurray, fire up the paper account and practice something, or pop open historical data and go candle-by-candle.
Practice one thing. For the love of god, practice one thing and ONLY one thing, and know what that one thing is. (Seriously - what's the thing? Write it down!) Maybe one kind of entry, with one kind of exit. Sure, when you trade live you've got a bunch of tools and tricks, and use them all. But when you intentionally practice, have ONE thing to focus on. Otherwise, how can you clearly see whether it was working, or whether you're getting better, or if you are PROFITABLE, when it's all mixed up in a bunch of maybes?
Be honest with yourself. Don't cheat. Log the trades, the losses and wins and the commissions and slip. Don't just eyeball old data and tell yourself you'd have made a motza. That's not practice. That might be ok to get some basic ideas, but reality doesn't work like that.
Note when it's going good. Print the charts. Stick 'em on your wall, mark the trades. DO THE SAME WHEN IT'S BAD. Notice anything different? Is the price action looking different? Is there some way to avoid those bad trades, but keep the good ones? Can you see the jaggy stupid wandering crud that tells you to stay the hell out of the market? Can you recognise that? Practice NOT trading that stuff, because seriously, staying out of bad conditions is something you need to do.
And that noting what's good and bad? Do it with the real trades! Real trades are the best practice, but it's messy. It's not just one thing you're practicing, so especially at the time you made the trades, you'll miss some of the details - you'll miss the forest for the trees. So on the next day, get on your computer a couple of hours early. Look over yesterday's trades. What was good? What was bad? Mark all the trades, and what you were thinking when you did them. Does REASON X keep failing? Does EXIT Y keep missing something obvious?
Don't - this is important - don't try to get all the pips. If you could, you'd be the richest person on the earth. You won't get them all. Don't kick yourself for "mistakes" that are only clear in hindsight. Practice, instead, being PROFITABLE, not being RIGHT. Can you introduce a new "rule", under some conditions, that would have made your old trades better? Fine, try that rule - and practice ONLY that rule for a while. See if it works when the bars are moving.
If all of that isn't fun, then quit. There are plenty of jobs on earth. Go do one you like.
There's no perfect trade. Ever. That's what makes this fun. Because there is ALWAYS something to do.
Found a WSJ piece from last year on them.
According to the above article, if Renaissance have an algorithm or 3 they clearly need some tweeking.
As i said, the fact that no infallible or even consistently profitable algorithm exists means that the data is useless for predicting price movement = patterns are useless.

if failure to remain consistently profitable or infallible for a period of 26 years somehow implies the data is useless, there might be a lack of understanding here about how algo is actually developed and used. Sure works for some. If something is useless, it certainly isn't the data.
Put simply, if Renaissance or any one else has an algo that worked consistently, they would use it and be profitable every year...Renaissance according to the first thing that popped up in a google search, operates some funds that are NOT consistently profitable.
Therefore i conclude (and struggle to see it any other way) that Renaissance does NOT have a consistently profitable algo.

I can't think of ANY business situation where every single transaction makes a profit. Not one.Put simply, if Renaissance or any one else has an algo that worked consistently, they would use it and be profitable every year...
Seriously good post "Weat" ... where have you been for the last couple of years.... are you and TH mates? :
You do like to write eh Weat! ..... Fortunately lots of us like to read..... good stuff.
(and struggle to see it any other way)
Given the market is really people when it is truly considered (where would the market be without people? Even algo is programmed by - well - people) we must check to see if data in relation to people is useless. This is the natural extension. If people use data to make decisions, even that knowledge is useful. However, if all data is useless, we are just random people doing random things. When I meet someone in the street, I might say "lovely grass ice-cream to your purple catfish umbrella" - burp - and place my left shoe down their shirt. The data I had for sentence formation and social interaction is useless. And thus this entire text is the result of a bunch of monkeys typing, after they finished a Shakespearian novel.
Could be. I don't have any useful data to know anything about the veracity of this. If all data is useless, I don't even know what the concept of veracity actually is. Maybe you are an algo housed within a cosmos which itself is entirely random. We don't actually exist.
...and now we are into the realm of reality and philosophy where it just might be that data is useless. Interesting perspective.
....Struggle away.
Hey, it's a complex issue, trading. If people want to stick to reading three-line posts, they'll never learn much of anything.
Also, I had a damn nice bottle of red after I finished last night, and that makes me talkative.
Though, yeah, I'll shoosh now. Gimme a few weeks to get properly settled, and I'll start a separate thread for the people who want to read slabs of text, rather than invade threads like a fungus, hahaha.
Hahaha, fair enough sir!
But here's my secret: I learn by teaching.
I catch myself holding vague, unformed ideas, unless I am forced to enunciate those ideas. I'll kid myself if I can get away with it.
Try to teach, and you have to get right at the bones of what you believe. You have to squeeze that fog down into a drop of actual water, and see if it's clean or mud.
Usually I teach an imaginary student in my head.
I'm chattering constantly to myself (mouth closed).

My wife who is usually in bed when I'm trying to sort out why I am the worlds worst trader often comments "who are you talking to"
