The average forex trader loses money.
Only the top few percent make money.
It is not like a regular job. Imagine professional golfing, where most players struggle to earn enough to travel to their next tournament, but then there is Tiger Woods.
So the idea of “salary” is not applicable. Most people will lose money. A small amount (like me) will make a living, but not get rich from it. A tiny remainder will take the whole pie.
