DislikedAs for the line charts, they generally use close values for their data points, and consequently certain timeframes also appear differently depending on the timezone (e.g. 4h, daily).Ignored
What will change like you say is the high-low points of the drawn lines, since the data points are obviously sampled again for display - 62,250 M1 data points in this screenshot, but only 500 pixels to draw them, so on average we have 124 M1 candles per pixel. Resizing the window does the same thing, however, and the effect is barely noticeable.
