umbertosm: Zoomingin or zoomingout or compressing the vertical scale of prices, or changing timeframe, this trendline stays put at a 45 degree visual angle. Therefore, the angle in degrees of a Trendline by Angle has no relation to time or price. Because angle or tan(x/y) must be unitless. X/Y is. A chart has price and time. Like saying what is the angle of a car going 30 miles in 15 minutes. Meaningless. You can specify the slope pips/time but not an angle.
