I have access to three books by Al Brooks, one on trading reversals, a second on trading trends, and a third on trading ranges. Today I took a look at a section in the one on trading trends in which Al wrote...
"All trends contain smaller trading ranges, and all trading ranges contain smaller trends."
But this is literally impossible! (Unless I suppose one is able to trade at the microscopic level.) At some point ranges become so narrow that, for all practical purposes, they no longer contain trends within them. The next sentence Brooks wrote was...
"Also, most trends are just parts of trading ranges on higher time frame (HTF) charts, and most trading ranges are parts of trends on HTF charts."
This is a much more reasonable statement because here he thankfully includes the word "most."
Brooks goes on to state that an important point to remember is that
"the market constantly exhibits inertia and tends to continue to do what is has just been doing. If it is in a trend, most attempts to reverse it will fail. If it is in a trading range, most attempts to break out into a trend will fail."
I would not disagree with this, but I look at it a little differently. I would say that if the market is in a trend, most attempts to reverse it that occur during periods of low liquidity/volatility and within the central regions of the asset's typical price ranges as established by historical price behavior will fail.
However, it is my experience that attempts to reverse that occur during periods of high liquidity/volatility near the outer regions of the asset's typical price ranges are moderately to wildly successful a statistically significant (high) percentage of the time.
Likewise, if the market is in a trading range, most attempts to break out into a trend during periods of low liquidity/volatility and within the central regions of the asset's typical price ranges as established by historical price behavior will fail.
But once again, it is my experience that attempts to break out into a trend during periods of high liquidity/volatility which are initiated from the outer regions of an asset's typical price ranges as established by historical price behavior will again be moderately to wildly successful a statistically significant (high) percentage of the time.
I apply this outlook to trading foreign currency pairs, but I've used it successfully trading U.S. indices as well. However, a critical factor in seeing it lead to positive results is being able to distinguish between insignificant price fluctuations verses confirmed launches in a new direction.
