Does anybody know of a trading related book written by Nasdaq market makers or NYSE specialists? I have read many books written by pro or amateur traders. They all seem to be saying look at the chart, when it is trending, by the pullback, or buy the 38/50/62 fib retracement, etc.. It will be really interesting to know how do market makers/specialists make their living. They have access to order flow. They can work large orders sent to them. Do they bother looking at a stock chart at all? How are they able to trade against all of us pro/amateur traders to make a living? Or is this secret of their trades (like magicians')?
