that's really beyond the scope of this thread because i don't know what your data was tested on and how it was tested. the only thing i can say is that one should try to cover and review *all* bases thoroughly when studying a system. investigate not just the core but every event. yes, it can be...

hard to do? yes. impossible? no. one should not automatically accept results that are derived from data mining processes, but one should not automatically reject them neither. you need a very analytical approach to understand what is valid or not. as for taleb, he is right on some...

which market? uhm... something that has amnesia. something that's happy one day and unstable the next. something that can't seem to ever make up its mind on what it wants to do. something that's always sensitive to every little remark. essentailly, something that acts like a girl. there are a...

dude, hit ratio is only one ingredient... what else is in the burger? does it even have any beef? 85% w/l with maybe 0.2% gain over average 5 day holding period is nothing special. that's like a sad ass burger i wouldn't even give to a homeless dog. but 85% w/l with 7% gain over...

http://www.elitetrader.com/vb/showthread.php?s=&postid=686687#post686687 did you put 100% of your capital on one single trade again? if the answer is yes, two big thumbs down to your trade.

"I pity the damn ignorant fool who attended and sat through a WIZE TRADE seminar. There are slow people in the world, and then there are WIZE TRADE attendees. " -Mr. T GREEN = BUY. RED = SELL. Jack, you paid 3 grand for this box? lol

some guy with a lot of fake knowledge here paid 3 grand to attend a WIZE TRADE seminar.... http://www.elitetrader.com/vb/showthread.php?s=&postid=327551#post327551 "dude, it's green! that's uh.. a buy signal! you're a genius, man. you can read colors!" :p:D

some people here obviously take themselves and the quality of their knowledge too seriously. amusing.

as this thread implies, they should really rename elitetrader to something else. maybe g.e.d.trader or something. :p

combine math with common sense and you might have a powerful set. there are some traders who are brilliant in math but suck in trading because they have no common sense. they're too square-headed to grasp basic human psychology or how things just are without math. and then there are the...

hell yea, hackers are dangerous! they're gonna steal all your money under your nose, man. you better hide your dough under the pillow or at least go to the backyard and dig up some holes to hide your wads.

it's portable.

yeah, that's net everything.

i think it matters psychologically. probably depends on your character and your level of forbearance. if you had a string of losers and you're waiting for that "home-run" to overcompensate, you might not sleep as well, right? i don't know. i don't touch anything that's below 75%.

if you had a system that had 90% winners, then 90% is the win rate. expectancy is the expected value from each trade. so if each winner gave you a buck, and each loser took two away from you, your expected value is: ( (90 * 1) + (10 * - 2) )/100= 70cents

traderich, i see so many giant red flags in your system i don't even know where to begin... this is the wrong thread to talk about it though. pm me if you want.

co-signed.

lol. cutten, do you know what are you talking about? 1.) the black scholes model *isn't*even a "system." it's just a formula. just a tool. not a trading system. the black scholes model does not give signals on when to buy or sell. 2.) as for its dependency as a model, that's weak...

that stock is clearly going to end up to be $500 or maybe more someday. it would be unwise to not put down a mortgage on this baby today. you'll regret later.

you're getting bad feeds.
