I cant help but think that's a crock...with enough information you can put percentages to likely out comes but there's always a random element that can determine the final outcome...depending of course on the nature of the event.
The more complex the event the more potential for a random 'happening' to determine the outcome....dumb luck is real.
Also think you guys are over complicating something that is in essence very simple.
Previous studies have suggested that there is an element
of predictive control in human stick balancing at the
fingertip. However, the fact that survival statistics for stick
balancing can be reproduced by a stochastic delay equation
having only an unstable fixed point raises the possibility
that the control is, at least in part, nonpredictive.
This suggestion is supported by the observation that the controlling
movements made by the fingertip can be described by a Levy
flight . Levy flights have been shown to be optimal for
random search patterns and have been detected in a variety
of search tasks including animal foraging strategies
and human eye movements during reading.
This observation strongly suggests that the nervous system is not capable
of predicting the movements of the balanced stick, but develops
a foraging strategy.
I like your enthusiasm for the topic. But anything other than limiting losses is about being right. Limiting losses is part of the numbers. Being right is about being right.Sorry, but I don't think the aim to minimise losses justifies moving a stop to break-even. Why break-even? Why not a few ticks above or below? Why precisely break-even? For psychological reasons.
But the initial stop guarantees a loss if hit. That affects the numbers.And it is not the most important stop in any case; the original stop is the most important and should be the most logically grounded.
LEVY FLIGHTS are random..
If I have a coin and it has a small bias to heads
What will turn up on the next TOSS ?
Hah! The rub comes in the inconvenient fact that we will never have enough information to predict systems like the stock market - enter chaos theory.
Wayne,
Speak for yourself, personally I have found definite sequences of events that make trading profitable, consistently. So did a number of Market Wizards in Jack Schwagers book, which is why they left the academic world to be traders.
In the academic world they see the market as random, because no-one can accurately tell where individual share prices will be at a future point in time, yet they do not study how a common series of events lead to certain outcomes with monotonous regularity (certain, as in high probability).

But I think that is exploiting randomness rather than disproving it.
Just on that note ... The best entries are often found at the spike extremities.... and a high percentage of the 'obvious" Stop loss levels are more often than not the best entry points ..... From my experience, rushing entries through impatience creates the most unwanted "heat" in any given trade situation.

brty said:Coin tosses are clearly not random, biased coins or not, not a smart example to use. I can toss a coin and get 20 heads in a row, with the first 20 tosses. I can take the same coin and toss it another 20 times and get 20 tails in a row. I'm a good tosser .
WayneL said:The point I am trying to make is that random <> randomness.
Isn't randomness just a noun?
Exactly. If we feel we need to increase a stop to allow for a likely spike, we should just delay the entry.
A good trader has such an edge that the issue of trade size is not risk, but comfort.
If my risk amount is already at an amount that is acceptable for me, why should I lower it? Why would I want to lower it? The goal is to make money, not to limit losses to minute amounts.
Why would I want to lower it?
e.g. Chaos is also a noun, but has a different meaning in science and mathematics than it does in the vernacular of the common schmuck.
Nomore4s said:By reducing risk and losses to minute amounts does this not make it easier to achieve the goal of making money?
Why wouldn't you want to lower it?
But the definitions for chaos are legitimate, but the common understanding of 'randomness' is not?
Wouldn't it be easier still to increase gains?
We already do that when we keep our risk amount constant. Why? Because any action that increases our edge - such as increasing the size or frequency of wins, or decreasing the size and freqency of losses - mathematically justifies a larger risk amount. By keeping it constant, then - relative to our edge - we're risking less than we were before.
I find it amazing that anyone could think the markets are random. As you say, there is reason behind every action and every participant - they're not monkeys throwing darts (even if the result is the same!), and even then, monkeys don't throw darts randomly either.
By reducing risk and losses to minute amounts I'm actually increasing my gains by improving my overall R/R ratio, and improving the overall gain to my account on my next winner.
Great in theory but not so great in application imo. $1 risked is still $1 risked and still affects your profitability and capital base when lost no matter how your edge is improved, so if you can reduce it to 50c why wouldn't you?
I did not wish this topic to disintegrate into a debate on random, that has been discussed in other threads. Suffice to say that random is a concept that occurs in the minds and theories of Mathematicians and Statisticians.
Motorway..
They are also only theoretical, and don't exist in the real world..

Stick balancing is not in the real world
and yes the debate will go back and forth
http://news.sciencemag.org/sciencenow/2008/02/27-01.html
But it is interesting distribution to study and certainly exists
Coin tosses are clearly not random, biased coins or not, not a smart example to use. I can toss a coin and get 20 heads in a row, with the first 20 tosses. I can take the same coin and toss it another 20 times and get 20 tails in a row. I'm a good tosser.
So you will not bet on my coin at all ?
Only one you toss yourself... So application is that you only trade shares where you control all the fluctuations / tosses ?

How many were lucky , how many since blew up ?

STOPS are about profiting from what we don"t KNOW or CONTROL .. WHAT IS RANDOM TO US[
Now where were we in relation to stops??
If you really control the fluctuations , the coin tosses you maybe don't need them
