Why don’t trend lines stay in the same place when I switch to different time frames on my chart?

Drawings are designed to retain a starting point and an ending point. These points are based off of time and price, the drawing simply connects the points. A trend line for example, has a slope associated with it and the angle of the line is dependent on how much space is in between the start and end points you select for that line. In other words, the angle of the line will vary due to the changing amount of space in between the points when switching through different aggregations.
