y = mx + c
It takes exactly two numbers no matter what time frame you draw a line at. Lines draw exactly the same and always match no matter what time frame, this occurs on any platform, and the size of the gap makes no difference and does not distort the line.
Personally I would like things like moving averages to be the one I select and not jump around depending on the time scale too. If I want to see the 50 day moving average, I want to see the 50 day moving average no matter what time scale, but I would settle for a simple line. I am also aware that other people do want 50 bucket moving averages, no matter what the bucket size.
By the way, are any people on here actually IG staff? How do you actually ask IG a question? The chat link that used to exist seems to have disappeared.
