I’ve always been a fan of volume and still to this day I like to keep an eye on it. Not so much the day-to-day volume, but more like when a significant technical level is broken. I also pay attention to the volume in the option chains. In fact, I probably spend more time in the chains than anywhere else.
I primarily trade the $SPX and as such track the breadth of the underlying components as that has proven to fit my trading style better. Volume will be what volume will be and I’ll continue to monitor it but refuse to fight it (or the lack thereof). Here’s a few of the key numbers I watch in the SPX as well as a nice visual heatmap from TOS of the broader index today.
