my friend, I have read both your questions, and I went back to find out this time and thought it over carefully. I think the William indicator should be that the number is small and the number is high. For example, when the indicator is at a high level of 1, the stock price should be adjusted back, but the stock price continues to rise, which leads to deviation, also called top deviation. The phenomenon of top deviation is generally a signal that the stock price will reverse at a high level, indicating that the stock price is about to fall in the short term, which is a relatively strong selling signal. The opposite is equally understandable.

I haven't found accurate evidence, but I have seen it in the image before, and I'm probably 7% or 8% sure of it.
