I don't know - you can't see how scrunched up bars are at the top unneccesarily and all that empty wasted space in the middle? I'm constantly adjusting my charts to best see what I need to see.
Yes, I know what you mean. Dead space can appear. I had that on my mind when I showed this other view without extra space. The answer to why it's in the thread is that I had that space filled with indicators. I had to turn off all indicators except the introduced one and forgot to resize the remaining charts.
Anyway the one indicator I prioritize with price (along with time, pattern and momentum) is Rate of Change unfiltered. Just price divided by price x number of bars ago X 100. Below one minute ES chart from Friday ROC set to length of 60 representing price change over an hour.
I've examined your Rate of Change indicator. In my analytics, I agree with everything you wrote except for maybe the "unfiltered" keyword. The ROC indicator can be combined with a moving average to filter out noise and identify more reliable trend signals.
How could an unfiltered indicator be better than the same with filtering algorithms?
