Yea. I was going to mention T&S is THE reliable volume indicator, but tape reading is a different topic.
i don't care if the DOM was 20 levels deep (i trade cbot so i see 10) there is a lot of fakery and gaming in the dom. a lot of hidden depth etc. simply put, the utility for most people is not there. cause the dom doesn't show real buyer and seller interest, only what people put up as orders to create false impression time/sales (tape) shows actual transactions, and is thus much more useful than DOM (or level II) level II was prolly pretty useful for a while in the 90's, but has caught on too much to the extent that the smart money uses it to try to trick retail traders.
