Hi Nooby_Mcnoob - Remember that Forex is decentralised so using info from a retail broker does not reflect all traders only their clients (or an aggregate if they have collated all retail traders somehow) - also the banks are 90% (or whatever the latest figures are) of the volume
Morning skredneck - Direction comes from the fundamentals ie primarily the Central Banks and Interest Rates and on a micro level the economic data releases and entry levels into the trades is executed around the trendlines
I have been a professional FX trader with a number of banks for 28 years, my last job was as Chief Forex Trader at Citibank. If you have any questions about Forex Im here to help. Hopefully I can give you some insight into how the bankers actually trade Forex.
