You should watch this 40 minute youtube video in which a forex bank trader discusses how the bank traders make their trades. You will be surprised to learn that very few of them use technical analysis. Why? Because banks are the market markers. Market making gives them insights that retail traders lack. Since banks are the market makers, they have to take an opposite position to every trade that is placed with them. Watch this video and learn how banks perform their roles of market making, what is order flow and how these orders get filled.
