Quote from Marsupilami:
This is also why many people come to the conclusion that all the known patterns such as double tops/bottoms, head and shoulders etc. do not have an edge because they often try to trade them each time they appear, regardless at which price level. I have been there too and it didn't work for me...
There are many academia research articles about their testing of such well known patterns as you've mention. Yet, the testing was performed via their own personal "trade management" method involving stops, trailing stops, profit targets or personal entry signal involving those patterns.
In fact, each author had different results for the exact same pattern. The results usually differed because of the trade management difference or others had different entry rules into the exact same patterns.
My point, why do folks bother testing patterns for academic review when their entry signal or trade management rules stink or not something any experience trader would use (rhetorical question). Simply, there will not an edge found if someone is going to test a pattern all by itself while ignoring all the other important pieces of the puzzle that's involved in profitable trading of these commonly known patterns that you've mentioned.
The edge is in the trader, in the entry signal, in the trade management and in other important things in the trading plan...in combination as a trading plan.
Just the same, a trader must be prepare to
adapt his/her trading plan when there's fundamental changes in the environment of their trading instruments to prevent or minimize drawdowns. Such adaptation is something most newbie or beginner traders will not have enough experience to do. That's why the real edge is the trader that's able to adapt his/her trading plan because patterns will always be the same (nothing new there) but the markets change many times every year.
Therefore, as soon as someone starts to talk about everything else that's involved in successfully trading that has nothing to do with a pattern that's being discussed in any given book...its view as
"ramblings" or too much information. That's why books that only talk about the pattern, similar to how academia approach testing a pattern...these types of pattern books, research articles will always remain on someone's favorite book list.
In contrast, a book that's gets into all that important stuff that's involved in understanding how to think like a profitable trader
before the appearance of any pattern and to profitably trade a pattern
after the appearance of any pattern...these books will remain on someone's boring or "too much" information book list...collecting dust.
There's more to profitable trading than just a pattern or bar to bar analysis. 100 traders that say it doesn't work while 1 trader that says it does work involving a
discretionary trade method...it should be obvious the edge is the trader and/or his/her trading plan of that trade method.
P.S. I don't know what's in Al Brooks books because I've never read them. Yet, if he's talking about other things in his book that seem like it has nothing to do with bar to bar or something that has nothing to do with a trade signal...there's probably good reasons for those discussions.
