Any idea if he's stopped using them in his trading process?
He didn't mention number lines, but he said that [paraphrasing] "simply buying A & C ups no longer works, so we are looking at more and Fisher bars are part of that."
From his description it seems like Fisher bars help combine price action with velocity and volume, which he believes is necessary in today's markets.
I don't know why he used the worst possible market (ES) to demonstrate this new indicator.
what does upside jan volatility look like compared to historical? that could be interesting since all we hear about is storage and bearish sentiment..
