Leverage is a privilege used by traders to set a profit or loss ratio. If someone invests 1 $ and sets a leverage of 1 $: 10 $ this is called leverage. traders with small investments must use low leverage to avoid big losses because there are more opportunities for beginners to lose. High leverage is used by experienced traders because they can understand trading conditions well compared to new ones. and Leverage helps to double profits significantly so that anyone can use low investment to make a bigger and better profit from each trade. So that's why we can invest as much as $ 40 and still make a profit of up to 20 dollars per day if we make long-term trading on the h4 chart.
