On my NT DOM, I always keep the cumulative volume (CV) on both bids and asks (across the 5 price levels) displayed. Previously, the CV would run consistently above 2000+ on each side, except prior to major news announcements. In recent weeks (with all this chaos in the markets), the CV is running less than 1000 per side (often in the 500 range), and the inside price volumes (at highest bid and lowest ask) are often only in 2 digits. Yet, we're certainly not lacking overall volume (as far as contracts executed per day). So what has changed? Are the computerized programs (run by hedgies and the big i-banks) no longer running? If so, what does that mean for us ES day traders who don't run black boxes? Good or bad? Personally, for scalping, I've found it much easier to get limit orders to fill, both on entry and exit.
