Quote from Trustme:
I disagree. Let's say you have pattern XYZ. This pattern produces positive results with a hit rate of 80%. Everyone knows this pattern, everyone trades it. Soon people would try to get in before the "dump money" and this would go on until the pattern wouldn't work anymore.
The answer, at least to me, why successful trading is possible - the game of GO or Poker. Even with huge processing power it should prove difficult to build a programme that beats a very good player.
The point gets interesting when you distinguish between pure mechanical trading and trading with a little human input.

First, this would presume that ALL traders figure out a pattern that works SOON. Patterns change all the time.
But you're right on the "dump money". This happens every day, on every stock - Everybody tries to get in "before"!
However, this is not the point - While ppl might be trying to get in "before" in their respective timeframe, there's always going to be a larger timeframe that overpowers that timeframe and thus makes people follow them religiously. You wouldn't try to go long just because you've broken a 5-minute resistance, while a 10-or 60- minute or even daily resistance is approaching, would you?
However, price will tend to move within these trend channels.
Assuming your theory would be to assume that people all trade in the same timeframes, as to battle for the same patterns. They don't. They all do their own thing in their own time, which is why regression channels, S/R and different MA's, for example, work.
Ever heard of the Indian (Hindu) belief that we're all little circles turning within larger circles, which in turn are turning inside even larger circles again? This is their perception of cosmos and god.
Certainly applies many times in trading.
If you want to argue that, I can prove it to you
Now - To mechanical trading - There are many advantages to mech trading , one of them being that human subjectivity is disregarded, the other being that you can, once the system is programmed, keep throwing in different parameters and declare different if = then / else functions etc to account for all different kinds of situations you might otherwise not be prepared for if you were trading purely discretionary.
Happy Trading,
