The leverage in Forex Trading is what allows the fast compound of money. However, it’s not all amounts that are duplicatable fast unless your skillset is very advanced.
In order to start seeing some fast results, it is very common of professional traders to advice aspiring traders to have at least a $10 000 starting balance. However, that amount is not at the reach of everybody, so in general the average trader opens an account with 500-2000$.
With that amount, which is considered pretty small, it is not suggested to trade for the money as the compounding effect might be very slow. With that proportion, a trader should use it to build a nice track record by workout his/her skills: make mistakes, rectify & fix them to improve the skillset.
Throughout time & progression, it is recommended to add more money in order to reach a decent amount that will allow bigger potential returns in the future.
