Transaction costs vary slightly according to the platform. Of course, we only discuss the spread here, not the extra cost of the platform, because this can be omitted.

For example, the spread between the euro and the dollar is basically 1.5-2, which is basically this range, and the difference is not very big. When choosing a platform, we should put the stability of the platform in the first place. It is suggested to choose the platform of NFA supervision in the United States.
