Higher Time Frame Indicator - page 2

Right or Wrong, I like to see if the signal line is coming in asymptotic or at a nice angle when it approaches zero. A stair-step line always looks like a shallow angle.
Below is a picture of an RSI being shown across all time frames as they would appear (not stair-step). I think what I am looking to do is possible? ---Tom
Sure, but you'd probably need to recalculate the buffer on every new bar.
