Foreign exchange, of course. Suppose the leverage is 400 times, the standard euro (100000 USD) is opened, and the margin is 250 USD. A jump point is 10 USD, which fluctuates by 60-200 points every day, that is, the margin of more than 2000 USD is 250. Do the math yourself and see how much it has turned over! ! If you want to play, I will tell you where to open an account.
