Trendline angle error
Trendline angle error

I perceive this to be an error.
Trendline angle is a function of rise over run, we all know that. Aka, Price-rise over Time-run.
However, your trendline angles change when either the price axis scale or time axis scales changes. This obviously changes the visual angle of the trend line on the screen, but it does not change the units of price-rise over time-run. Therefore, the angle of a trendline should not change, because the units of calculation have not changed.
Note that the screen-printed units of rise / run do not change when time or price scales change.

Hi dmn,
Ok I understand now. I checked TradingView. On changing the chart axis scale, they keep the angle fixed and they change the end point. In contrast, we change the angle and keep the end point fixed.

Hi dmn,
Can you please share with us how did you come to this conclusion?
"Trendline angle is a function of rise over run, we all know that. Aka, Price-rise over Time-run."
Time and price are different units of measurement therefore they cannot be used to calculate an angle. The angle is calculated based on the actual screen dimensions of the chart.
