There are some very large, well-capitalised, and intelligent participants in foreign exchange markets, such as hedge funds and central banks. Any rational trader could be forgiven for being intimidated by the thought of competing with such financial behemoths.
The reality though, is that the retail has an edge in being small and nimble. A retail trader can get in and out of the market at a drop of a hat, without having to consult anyone. They just need an advanced forex trading platform.
Think of it like a hedge fund is an oil tanker, and a retail trader is a jet ski. If a big wave is coming, the jet ski can turn around and ride the wave in an instant, but the oil tanker will take ages to turn around.
