A trend is a trend is a trend. But the question is, will it bend? Will it alter its course thruogh some unseen force, and come to a premature end?
The financial markets can move in two ways – trending, or flat. The trendline is the BASIS of technical analysis. An up trendline is a straight line drawn along successive
reaction lows that moves up. A down trendline is a straight line drawn along successive reaction highs that moves down. So how do you draw a trendline? Obviously, to draw any line, there must be two points. For an uptrend to be drawn, there must be two successive lows, the second higher than the first. Draw a line between those two lows, which is now your trendline. But for your trendline to be validated, prices should touch and bounce off the line a third time. Same thing for a downtrend. There must be two successive highs/peaks, the second lower than the first. Draw a line between those two peaks, which is now your trendline. For your downwards trendline to be validated, prices should touch and bounce off the line at least 3 times.
In summary, two points to create a trendline, a third to confirm the line.
How Trendlines can be Used
- Once a trendline is drawn, one can assume that the trend will continue at it’s current rate.
- Trendlines become a level of support or resistance. A downtrend line becomes resistance once the price moves up and approaches the line. An uptrend line becomes support once the price moves down and approaches the line.

Thank you, too, for the explanation. It does make sense somehow… it all does go hand in hand with the business cycle: expansion, boom and recession.
Much like the difference between weather and climate. a patterns in short spanned and a trend in long term.
Love the quote at the beginning
And thanks for the clear explanation of trendlines….
