this uvol/dvol comparison chart is the picture pefect patttern for a directionless day, the up vol over dvol was never more than 3/2 all day
I read your posts on the ES Journal and know that you're a practitioner of intermarket confluence.
When I started out on the ES, I used the intermarket relationships approach as well. I looked at the DOW, XLF, XLE, UVOL/DVOL, VIX, TICK.
I found that looking at them made decision-making difficult and long. It's alright if you're holding for longer periods, but even for intraday swing it messed me up.
Also, that a lot of them bred the same hindsight bias I had with the primary instrument. For example, we know that uvol/dvol was never more than 3/2 all day, but we know that only because the day's over.
The argument can be made that statistically, if uvol/dvol is less or more than X by a certain time of day, then it's likely to do Z. But I haven't crunched numbers on that or looked at it for two years. I used to have a ton of lines and multiple indicators on my charts but I've been steadily cutting down.
