My understanding is that the relationship between leverage and risk is not like this. No matter how big the leverage is, as long as the risks are well grasped and the positions are well managed, the leverage is the same, whether it is 100 or 500.
The main difference of leverage is that the greater the leverage, the more money you turn over, but if you explode, your remaining funds will be correspondingly less (depending on the size of your position), and vice versa.
If you have a 500-yard lever 100 times, place 0. 1 lot, and the profit and loss per point is 1 USD. But after the explosion, the account was only about 100 dollars.
If it is 200 times, with 0. 1 lot, the profit and loss per point is $65438 +0. After the short position, the account is only about 50 dollars.
Therefore, the size of leverage, in practice, I think is mainly determined by the size of the amount of funds. If the capital is large and there are tens of thousands of dollars, then 100 times will do. If it is only a few thousand dollars, it is more appropriate to choose 200 times.
