Quote from NihabaAshi:
"I just want to get you on record exactly what you mean by anecdotal evidence while you consider someone's success in trading the pattern for many years with verifiable proof not good enough as evidence. "
Anecdotal is anytime it is based on someone's opinion, rather than on statistical testing on a large enough sample to verify its truth.
For example, when someone is "successful trading the pattern for many years", this leaves such problems as:
1) Was the success possibly due more to money management or other techniques? i.e., did he hold & hope or take prudent losses? Did he use have a magical touch with cutting losses and letting profits run? There is a theory that one can use random entries/exits and still make money with prudent money management....
2) Was the trader really successful or just pumping himself up, as is the case with most ET traders?
3) Was the trader lucky? When you have 1000 traders, some of them can have a multiyear lucky streak, just due to basic probability.
4) CTA performance results are not encouraging, as most of them favor TA methods, but are either negative or barely positive, and that is biased favorably by those who go bust/out of business each period and no longer report results
Again, anecdotal is not a reliable method to prove the vailidty of TA. This is the problem of alternative "medicine" and other fields.
Ok...I actually see your point and agree with
some things.
As I mentioned many times...I don't use indicators and I do know this TA debate is really only about indicators.
Have I used indicators in the past?
Yes.
Was I profitable when using those indicators?
Yes.
Was I incorporating other market info to help in my use of the indicators?
Yes.
My point is this...I haven't met ONE trader in my +15 years of trading with real money that
purely uses an indicator with no other variables involved (psychology, money management, fundamentals, seasonal tendencies et cetera).
That's my point is it seems like your trying to find someone that
purely uses indicators with no other inputs in their trade decisions.
Please correct me if I'm wrong.
If I'm not wrong...
I wish you all the luck in trying to find someone like that because I've never met a trader like that and such may be the reason why you will never find such evidence involving indicators.
This is a problematic aspect for system designers when they meet profitable traders because the system designer cannot code or has too much difficulty in trying to code in those other variables.
The main problem is the
most after a few months of using indicators will begin to
naturally see the importance of discipline, money management, properly capitalized, cost of trading (fees), understanding the price action et cetera in their trading results.
Note: They are using other variables but just don't consider them critical aspects of their trading until later when they get more trading experience.
It's a natural trading process and if you have an account deep enough or your lucky enough to survive the first critical year of trading...
You begin to incorporate those other inputs into your trading.
This is the reality of trading (no theory junk).
Once again, if you can find someone that's
purely using indicators via a method that would prompt you to say TA works prior to them naturally getting to the point in their trading when other inputs begin to gain importance...
Good luck.
Also, I strongly disagree with
marketsurfer views that once other inputs are involved it becomes subjective (art form) due to the fact that the commonly known inputs or variables that I mentioned above can be rule based and quantified.
Those variables are
essential aspects of successful trading and when he implies that if those variables are used to enhance the performance of any TA method...
They will
taint the results (my words and not his) is absurd.
Last of all, you are a
system designer, your the last person on this planet someone want's to prove (give you their method) that they have an edge especially if they fear they will lose that edge.
I'm done with this thread now.
