DislikedWow, so many questions. Who is going to answer that :-) ? All I know is that central bank have the power to manipulate price by modifying the spread. This means they can control a price level they want and force price to turn. Other banks, funds, large private traders have to sweat a lot to get their positions running. They have to drive price to liquidity, to stop hunt etc. They don't have the luxury of controlling the market with spread and news manipulations. but you don't need to know all of this to make money. You just need to know how money...Ignored
about why this and that, I'll leave it to the academician
In the end its just a stupid numbers game
