This is divided into two situations.
1. is your own account. This is basically to share the profits with the people who help you in stock trading, and most people around me are divided into three parts.
2. You are an agent, and you want to find someone to help your clients speculate in foreign exchange. This is calculated according to the number of orders placed when the account is profitable. If the commission is 5 points, at least 2 points should be given to the trader.
The above is what the traders around me look like. Of course, if the trader's skill is not very good, the score will be lower.

It depends on where you open an account. Different account holders have different fees. My friend's gold speculation in IKON is 5+4(5 points difference +4 commission).
