Mathematically Predicting the Future?

Quote from Thunderdog:

You may call it that, but it's not really the case. To calculate expectancy you need a probability distribution of future market prices. Such a thing doesn't really exist for future prices no matter how much we may squint to try and make it so. What you have is an approximation based on guesstimates or past data. Hardly the stuff of mathematical precision.

Similarly, a calculator is an electronic instrument that allows you to take two seat-of-the-pants estimates, multiply them, and get accuracy to the 8th decimal point.

You left out my smiley in the quote. I was a joke, but thanks for your serious reply.
 
Quote from MarkBrown:

in the old days i could predict the profitability in a position by whether or not i got a good fill. if the fill in the sp pit was quick and good price. the market was about to kill me. if the fill didn't take place then of course the trade: had i gotten it off would have made tons of money. ;)

It seems not too much different on screens now... :D
 
mathematically it is not possible to predict the future.

however i do know some hedge fund managers who use current indicators and numbers to know what the situation is and the immediate short term future.
 
Quote from MarkBrown:

ok it has been said that someone possibly could predict the market one bar in advance. what about predicting the price action like 20-30 bars in advance?

if you could do that you could make some money. but i dont even think you would have to be that accurate either to make big bucks.

Just use a monthly bar and have your model spit out next months high and low. thats close to 30 days.

As for un-related stuff used for prediction ask in alt.gann.astro.tinfoilhats :D I hear the serious planetary parctioners like to call it "natural law" so people dont thik they are loopy.
 
ok so what would be the difference between a prediction and an expectancy?

if i have a model and certain criteria is met and i know that in testing that when it does "this something" most likely the market will do something like go up, down or maybe sideways. if it does this with a high degree of probability. what would this be called?

by going to sleep tonight and resting - have i not just expected to wake up else i would not go to sleep ever.

or

tonight - i say to my wife i will see you in the morning because i know without a doubt there will be a tomorrow, at least in my mind? now is that a prediction.

if i tell you that i have observed you and from your traits i know that you will do something like itch your head or pick your nose. have i that power of prediction?

i wanna stick around if i can for anyone (some yet to learn) knows i am the cornucopia of trading ideas. hang in there maybe we will get there, wherever that is. :D

Mathematically Predicting the Future?

Has it Can it be done? As I watch, look and read everything available about trading I have to wonder where did all this junk come from. More than ever I think many people talking about trading using this and that method. Meaning the methods are not purely mechanical, I think we have and are going backwards.

Man in not progressing forward, it seems we are just becoming a Byzantine trading society. We just jewel up a moving average and get some guy on a video saying had you done this and had you done that you would have - could have made this on that trade. Where's the beef? Hey just forget all that stuff tell me where to buy it and where to sell it etc.

Mathematically is it possible, can man define the markets and surround it with a mathematical fence? Pull the market around on a leash like you were walking a dog? Sophisticated software with Ph.D.'s and global knowledge and light speed communication all at our fingertips. Why is it that the perfect trading method does not exist or does it?

Inquiring Minds wanna know, your thoughts. mb


thought i would respond cause i have nothing better to do right now.

Your original question is not the one you ought to be asking at this point.

identify your trading fractal (time frame).
identify your desirable trading frequency during the ebb and flow of the market during the day.
identify the point of change in this ebb and flow where the old trend is ending and the new trend is beginning.
enter now.
hold in this new trend.
reverse from one trend to the next when that special point of change appears again.

notice in the above prediction is not a prerequisite to success nor is it employed.

notice in the above that you are simply keeping up with what's happening now. sometimes the market is a little tricky and requires you to do a couple reversals in short order...mostly this is not the case. You bank profits between reversals.

I told you what you have to do to make money in the market consistently. You simply need to devise a method for doing so...and it has nothing to do with prediction.

It is anticipating the car in front of you changing lanes even though it didn't use a turn signal...you've seen it happen many times before and you simply 'know' what will happen.

i certainly appreciate the advise and will keep your suggestions in my mind as i struggle to make it in this almost impossible business. mb

start up the md600 were going to vegas tonight...

From a philosophical standpoint it is not...

Lets face it, lately ET is not standing out for its discussion of practical trading ideas.

From a philosophical standpoint you are right.
