Does anyone do that? Seem like some masters can really do high frequency manual day trade by looking at live price, bid and ask prices. Any book/article/research/people suggestion?
There are subtitles in most of videos. But it is not the aim - just wanna show that trading using tape reading is something normal. But all in all need to spend some time to prepare strategy for this kind of trading.
knowing what will likely happen before it does by studying the book, and being able to tell real activity from spoofing, etc.
That's my concern with it right there: one ends up investing a great deal of effort trying to guess icebergs and fakes vs legitimate bids and offers, reducing the amount of attention available for the rest.
Everything in speculation is guessing. Only the deluded think otherwise. I just prefer to base my guesses on whats about to happen rather than some kind of historic record.
