This isn't exactly foresight but I have no place else to put it so . . .
I was moseying around the internet for reasons that aren't important and came across this article about trending and ranging and how stocks or whatever trend only 30% of the time and so you want to buy things that are trending and not ranging. The following example was provided for something "trending":
And this was provided as an example of something "ranging":
There's just one tiny problem (though it isn't a problem for the SLA).
There are tons of ranges in the "trending" chart:
And as for the "ranging" chart:
(my apologies if this seems sloppy; it's difficult to distinguish between wicks and grid when they align)
Point is that the meme about stocks, etc trending much less than they range is meaningless. There are obviously trends within ranges, and if the ranges are wide enough, the trends don't even have to be scalped. Similarly, a "trending" whatever is going to be ranging periodically in order to take on provisions, enable latecomers to arrive, go to the restroom, visit relatives in the area. That the trend appears to be "broken" when these ranging moves take place is to misunderstand the nature of trend, which is why a "break" in and of itself is insufficient reason for exiting a trade. What if, for example, a trader in the first stock were to exit every time price rested? He might not lose anything, but he would be faced with the propect of re-entry, and that as we all know can be a giant PITA.
Which is all the more reason for knowing the rules and applying them without bias. One needn't even come up with an elaborate definition of "range" involving overlapping bars and lack of headway up or down and a volume component and so forth. One need only follow the rule regarding chop and stop trading when that situation presents itself. No decision-making required. It isn't even something that one need think about. Which can awfully calming.
