Yes, that is true. because if we take high risks then maybe give us a high profit but if we are wrong then what happens. if there is a big loss then we need so much time to recover our losses. so it's always better to use low risk even though the profit is less. maybe you can get $ 50 a day, but it is very risky. The trick is scalping, you draw a little advantage in a narrow well. Without installing stop loss, and you have full concentration. And you should also use more than 50% margin so you can open multiple positions
