My current main concern with trading software is position sizing. In particular, is Amibroker doing a better job than its competition with calculating and updating the Kelly fraction? I'd love to get a good answer on that one.

For traders, there is no exact Kelly formula. For traders, there is a Kelly equation to be solved. The most well-known Kelly "formula" for traders is a grotesque overestimation of the true Kelly solution. It is this account-busting overestimation that is responsible for Kelly's negative...

So is your method of guessing when a streak is going to end working for you? I don't try to guess what price is going to do, I observe what it is doing and respond accordingly. So what if I lose one big bet because a win streak suddenly ends? The big bets I won beforehand more than make up...

So if you shouldn't Martingale, there is no money management here? That's just sad, dude. To answer your previous question about what common sense has to do with the thread topic: Assuming you truly want to succeed at trading (not everybody really wants to), common sense says you should...

Lol You revived it yourself just last month. Your pretense that you're over this topic doesn't wash. The truth is, you're a degenerate gambler who is now using trading to place your bets because you're bored with craps or the horses or whatever. I just wish you'd shut the fuck up about it...

I certainly see the aptness of the Simple part of your name. Welcome to my ignore list. Good riddance.

I never showed him any disrespect, that didn't stop him from being a troll. Fortunately I don't need his expertise, I have my own. Position sizing has been distilled down to a science. I've posted that science here. Anybody who doesn't get it by now isn't ever going to get it.

I'm the guy who posted the correct Kelly equation for trading to this website but I don't have a degree in mathematics. There is a multi-sockpuppeted troll here who has a math degree but he hasn't seen fit to share much of that expertise with the rest of us.

:cool:

Stop lying. You didn't ask crap about mathematics in the first post, you asked if anybody (else) had fooled around with doing the opposite of what both mathematics and common sense says you should do. Sounds like loser-speak to me. :p

That's not the only problem. The Kelly formula proves that you should decrease position size during a losing streak. The OP is a gambler. This is a trading forum, not a gambling forum. Nuff said.

With OPM you're doing a hell of a lot more work. Just up the fee if your signals are worth a damn, then trade them yourself once you get a large enough bankroll.

I assume the price differential comes from the fact that forex traders tend to be cheaper or generally more low-rent punters than stock traders and you want to demonstrate that what you're offering (or pretending to offer) is of value to real players, not pikers. My question is how do these...

Kelly sizing. Everything else is bullshit. See my threads on the subject. http://www.elitetrader.com/vb/search.php?s=

Save your suggestions, I've aced every math course I ever took, up to and including advanced calculus. So I'll make this simple even for someone as admittedly challenged as you are.: A trend is directional bias. A drift is directional bias. It's not rocket science. You can actually...

Bullshit. Try Logic 101. Thanks. +1 :)

"Sugar daddies paying for college degrees" Maybe this explains why there are now more chicks than guys in college. :D

+1 Good grouping.

For the experience of not learning to cut their losses short? Are these the same idiots who hold their hands over burning candles because it feels so good when they stop? :D

Well, yes but evidently not the reason you've assumed. :p
