The difference between a professional trader at a hedge fund and a trader at an investment bank is far greater than what retail traders imagine.
As an institutionally trained trader, I started off in a graduate scheme at an investment bank where I was first put in an intensive 6-week training programme at the start of my trading career. This taught me the essential statistics, economics and drivers of the market. However, to put this into practice, I saw first-hand how profitable traders consistently go through the same framework and process which is very similar to one and another, but world apart from retail traders.
