In your screenshot, there are two transactions. Empty pen, good hand. The other one does more and has two hands.

The calculation of floating point is based on the trading point (whether long or short) when you open the position. For example, if a 3000-point short order falls by 2900 points, then the floating point is 3000-2900= 100. At this time, the floating profit is100 * 300 = 30,000 yuan (one point of stock index futures represents 300 yuan). But unfortunately, if the price rises to 3 100 instead of falling, then 3000-3 100 =- 100, and the floating point is-100, that is, the loss 100 * 300 = 300000.

If you make more than one order, the calculation is the same.

Floating profit and loss, it is said that the floating profit and loss points are *300, and the above 84*300=25200, which is completely correct. Because there are 2 lots below, it should be 84*300*2=50400.

Calculation of deposit. For example, according to 3000 points. 3000 * 300 *18% =182000. The calculation datum here changes every day. Generally, the settlement price of the previous day is used as the benchmark for calculating the deposit the next day.

I hope it helps you.
