If you’re basing your trading strategies on trend-line analysis, you need to be aware that price levels derived from trend lines will change depending on the slope of the trend line. The slope of a trend line refers to the angle of a trend line relative to a horizontal line.
The steeper the slope of the trend line, the more the relevant price level will change over time; the shallower the slope, the more gradually the price levels will change with time.
