Analysis of the principle of speculative foreign exchange trading: foreign exchange margin trading is that investors use the trust provided by banks or brokers to conduct foreign exchange transactions. It makes full use of the principle of leveraged investment, and it is a long-term foreign exchange transaction between financial institutions and between financial institutions and investors. In the transaction, investors only need to pay a certain margin to trade with a quota of 65,438+000%, so that those investors with small funds can also participate in foreign exchange transactions in the financial market. According to the level of foreign developed countries, the general financing ratio is maintained at more than 10-20 times. In other words, if the financing ratio is 20 times, investors can conduct foreign exchange transactions as long as they pay a deposit of about 5%. That is, investors only need to pay $5,000 to conduct foreign exchange transactions of $65,438+$0,000,000.

Investor A conducts foreign exchange margin trading with a margin ratio of 1%. If investors expect the yen to rise, they can buy the yen with the contract value of 100× 1% through the actual investment margin. If the exchange rate of the Japanese yen against the US dollar rises by 1%, then investors can make a profit of $654.38 million, and the actual rate of return reaches 100%. However, if the yen falls 1%, investors will lose all their money and all their principal. Generally, when the loss of investors exceeds a certain amount, traders have the right to stop the loss mechanism.

The method of contract spot foreign exchange trading can be to buy at a low price and then sell after the price rises, or to sell at a high price and then buy after the price falls. Foreign exchange prices are always fluctuating. This method of buying first and selling later can not only make profits in the rising market, but also make money in the falling market. If investors can use this method flexibly, they can gain and lose. So, how do investors calculate the profit and loss of contract spot foreign exchange transactions? There are three main factors to consider.

First of all, we should consider the change of foreign exchange rate. Investors can make money from exchange rate fluctuations, which can be said to be the main way to make profits from contract spot foreign exchange investment. The amount of profit or loss is calculated in points. The so-called point is actually the exchange rate. For example, 1 USD is converted into 130.25 yen, and 13025 yen can be said to be 13025 points. When the Japanese yen fell to 13 1.25, it fell by 65438+. Every point of each currency, such as Japanese yen, British pound and Swiss franc, represents a different value. In contract spot foreign exchange trading, the more points you earn, the more gains you make, and the less points you lose, the less losses you make. For example, an investor buys a 1 contract at a price of 1.6000. When the pound rose to 1.7000, investors sold the contract, that is, they earned 1 000, and the profit was as high as $6250. Another investor bought the pound at 1.7000. When the pound fell to 1.6900, he immediately threw away his contract, so he only lost 100, that is, he lost 625 dollars. Of course, the number of gain and loss points is directly proportional to the number of gain and loss points.

Secondly, we should consider the expenditure and income of interest. This article describes that buying high-interest foreign currency first will get some interest, but selling high-interest foreign currency first will pay some interest. If it is a short-term investment, such as the end of the transaction on the same day, or within one or two days, you don't need to consider interest expenses and income, because the interest expenses and income in one or two days are very small and have little impact on profit and loss. For medium and long-term investors, the interest issue is a crucial link that cannot be ignored. For example, if an investor sells the pound at a price of 1.7000, a month later, the price of the pound is still in this position. If you sell pounds and pay 8% interest, the monthly interest will be as high as $750. This is also a big expense. Judging from the current investment situation of ordinary residents, many investors pay more attention to interest income and ignore the trend of foreign currencies, so they all like to buy foreign currencies with high interest rates, resulting in more losses. For example, when the pound fell, investors bought the pound. Although a contract earned $450 a month, the pound fell by 500 points a month, losing 3 125 points. Therefore, investors should put the trend of foreign exchange rate in the first place and the income or expenditure of interest in the second place.

Finally, we should consider the expenses of handling fees. Investors buy and sell contract foreign exchange through financial companies, so investors should include this part of the expenditure in the cost. The handling fee charged by financial companies is based on the number of contracts bought and sold by investors, not on profit and loss, so this is a fixed amount.
