Probably should. Maybe ask these guys, who run probably the most profitable hedge fun of all time: "How scientific is it? Do you actually use models from science? The approach is scientific. Scientific sophistication is important. Do we directly apply the Navier-Stokes equation? No...

Prediction: trades will start out free, be capped within 6 weeks at 10 trades a month, and will be "free" as in NetZero's concept of "free" within 6 months. At least they didn't call themselves TradeZero or something embarrassing like that when they have to change their minds. Fletch

Marry an equal earner, double buying power. Next question? Fletch

You'd get a better response if you dropped the 45 minutes of patter while setting up for your 15 second trick, like some lame amateur street performer. OK, so your strategy focuses on sentiment. What about it? Fletch

Again I agree, but in practice what matters is probably somewhere in between these two sides of the argument, because we usually don't make enough trades for any given strategy for the asymptotic results to be the only thing that matters. Trade frequency is an important variable for this very...

My tail is getting skinnier the longer I sit at this damn computer. ;) Mind if I ask how long you've been at this game and how it's going so far? Fletch

Every losing dollar there has to be a winning dollar. But it seems one person could win $10 while 10 lose $1. Or ten could win $1 while 1 loses $10. Agree it seems like an argument for trading stocks over futures. Agree. I think the next few years will push the vig down in online...

Most are losers. Not news. Fletch

I would have doubled my $10k account. :( Fletch

I agree with that in general, although you could make similar arguments for 70% win rate strategies, when the winners are small per trade. If you put a little extra slippage per trade, your consistent winners become consistent losers. I don't think high win rate systems have a monopoly on...

If you want to amend that slightly to say "math skills are not sufficient trading skills", I will agree wholeheartedly. Did I say that? All of those things are central to the game of poker, and I believe are skills that will likely translate. Agree 100%. Fletch

Just some P/L to keep things current: Since 9/6: -$210 over 6 trades I made a really dumb Tradestation error and ate an $800 loss for no good reason. Things got out of sync with my historical orders and all hell broke loose with trade confirmation off. At least I learned that lesson...

He said futures, which implies the latter. Fletch

Agree. ET is 99.9% a waste of time. But maybe if people who go around slinging insults and calling people liars get called out from time to time, they'd behave better. Fletch

Interesting. You know this how? Fletch

No, but I've got an air compressor, if you want to give me your BMW, I can keep your tires full pressure, and we'll share it 50/50. Deal? Fletch

Thanks for your feedback Murray. I think your explanation is reasonable. I still have an itch to fully understand, however, why successful edges in the market can't be leveraged into a fortune in a relatively short amount of time. This is a general question and has nothing to do with you...

Well I have a PhD in math, so your comment rings a little hollow. Perhaps you are using different definitions for your words. And getting upset about something like this is something you should have grown out of about the timeframes you mention. Fletch

Murray, I have a similar background and have found the "signal processing approach" to be fairly worthless as well. But, I have a different question for you, and I don't intend it to be an attack, it's a respectful question that I hope you can answer openly, because I think it's a fair...

He said avg win:avg loss was stated per contract. So no, it isn't. Fletch
