An algorithm: current market value-purchase principal
Subscribe 19000 shares according to the net value of 1.02, and the subscription market value =1.02 *19000 =19380.
Now the net value is 0.8 1, or holding 19000 shares, and now the market value of positions = 0.81*19000 =15390.
Profit and loss =15390-19380 =-3990
The second algorithm: (net present value-net purchase value) * number of shares held.
(0.82- 1.02)* 19000=-3990
No matter which algorithm, the fund is negative 3990 yuan.
Extended data:
The floating profit and loss of a fund refers to the floating profit and loss of a member's open contract calculated by the settlement institution according to the settlement price of the current transaction, and the amount of the deposit payable for the open contract is determined.
The calculation method of floating profit and loss is:
Floating profit and loss = (opening price settlement price of the day) × positions× contract unit handling fee. If it is positive, it means that it is a long floating profit or a short floating loss, that is, the price increase after the long position is a long floating profit, and the price increase after the short position is a short floating loss.
1.？ If it is negative, it means the floating loss of bulls or the floating profit of bears, that is, the price drop after bulls means the floating loss of bulls, or the price drop after bears means the floating profit of bears.
2.？ If the margin is not enough to maintain the open position contract, the settlement institution will inform the meeting to make up the difference before the market opens the next day, that is, to add the margin, otherwise it will be forced to close the position. If there are floating profits, members can't put forward the profit part, unless the liquidation contract is closed in the future, and the floating profits become actual profits.
