Alright, back in the day when I was trying to learn how to trade, I spent lots of time watching the DOM display. I read so much info about it, gurus on ET claiming that it's "all they need" and they "don't even need to look at the charts" (lol, don't Woodie's followers say the same thing?). I never got that. I thought maybe whichever side had more open orders would attract price. Nope. It was random. I thought maybe whichever side had fewer open orders would attarct price. Nope. It was random. I added crap like bar charts, totals, all these cool options to mY DOM screen to give me all sorts of information about the orders. No patterns. No predictibility. It was random. I read the theories that said "price goes where the orders are." Market makers don't care where price goes, they just go where the orders are. This seemed to be true about 50% of the time. lol. But I do have a question: Who decides which way price goes? Say price is currently at X, and there are orders at X, X+1, and X-1. Actually, ignore the orders at X. Say there are orders at X+1 and X-1. Equal numbers of orders, or unbalanced, it doesn't matter, you pick. What determines whether price goes to X+1 or X-1 next? Also, why does it skip over numbers sometimes? Price will be X, and there will be orders at X, X+1, and X+2, and X+3, yet the next tick will be X+3. Why did X+1 and X+2 get skipped over? Conclusion: DOM movement is random (because price is random) and provides no edge (at least not to a human trader).
