If you’re looking at ten years of daily prices, you get a different view of trendedness
than when you’re looking at only two years of data. In other words,
you need to consider the time period of the data you analyze. A security may
display a trend on data captured every hour but appear to be nontrending
when you look at daily data. Some securities may trend in the morning and
not in the afternoon. To go to the other extreme, you may not be able to
detect a trend on daily data but a weekly or monthly chart shows a trend.
You cannot say anything reasonable and useful about trends without specifying
the time frame.
Further, a security that trended in one period may not be trending in another.
Markets are dynamic. They change (then they change back). Accept it.
Embrace the spirit of empirical investigation embodied in technical research.
When you’re drawing charts, experiment with different time frames.
