It's about some problems. The 50,000 units are 0.5 lots, and the margin is $500, which means the margin leverage is 1: 100. A little 0. 1 hand is equivalent to 1 dollar, so you earned 247 points, which is 0.5x 10x247 = 65438+. If you earn $7,465,438+0, it means that you placed 0.3 hand instead of 0.5 hand, and 0.3x10x247 = $7,465,438+0.
