1 Yes, 500,000 yuan can do 4 lots-but short-term in the day is ok, and the risk is very high overnight-the margin fluctuation is not enough at all. The margin ratio of 15% has advantages and disadvantages, while that of Guo Xin is 13%.

The minimum change of the stock index is 0.2. If you mean a change of 0.2, then the return is 0.2 * 300 = 60. You should also deduct the transaction fee.

If we calculate rate of return on capital, we take 500,000 yuan as the benchmark, the change of one percentage point is 1%, and the rate of return is = 400,000 *1%15%/500,000 =5.33%. That is to say, in this case, the proportion of handling fees is very small, so I don't know what yours is.
