There are five fund codes, namely: 510050 50tf510880 bonus etf510180tef159901deep100tef. DIF refers to the deviation value, which is an index in the technical analysis of the stock market. It is abbreviated as DIF, that is, the EMA value of 12 minus the EMA value of 26. In the continuous upward trend, the moving average of June 12 is above the moving average of the 26th. At the same time, the positive deviation (+DIF) will become larger and larger. On the contrary, in the downward trend, the deviation value may become negative (-DIF) and become larger and larger.

First, judge the difference in skills from the value.

1, DIF value and MACD value all move up on the x axis, and the market is a bull market, and vice versa.

2. On the X-axis, when the DIF value goes up through the MACD value, it is a buy signal. This crossing under the x axis is only suitable for short positions.

3. Below the X axis, when the DIF value crosses the MACD value, it is a sell signal. This intersection on the x axis is only suitable for bulls.

4. Deviate from the signal. When the trend of exponential curve is upward, but the trend of DIF and MACD curve runs counter to it, there is a signal that the general trend is about to turn around and go down.

2. Transactional open-end index fund, also known as exchange-traded fund (ETF), is an open-end fund with variable fund share listed on the exchange. Transactional open-end index fund is a special type of open-end fund, which combines the operating characteristics of closed-end fund and open-end fund. Investors can buy or redeem fund shares from fund management companies, and at the same time, they can buy and sell ETF shares in the secondary market at the market price like closed-end funds. However, the purchase and redemption must use a basket of shares for fund shares or use a basket of shares for fund shares. Because the securities market transaction and the subscription and redemption mechanism exist at the same time, when there is a price difference between the ETF market price and the net value of the fund unit, investors can carry out arbitrage trading. The existence of arbitrage mechanism makes ETF avoid the common discount problem of closed-end funds. According to the different investment methods, ETFs can be divided into index funds and active management funds, and most of the ETFs abroad are index funds. ETF launched in China in 2022 is also an index fund. ETF index fund represents the ownership of a basket of stocks, which refers to the index fund that is traded on the stock exchange like stocks, and its trading price and fund share net value trend are basically consistent with the tracked index. Therefore, investors buying and selling an ETF is equivalent to buying and selling the index it tracks, and can get basically the same income as the index. Usually, it adopts a completely passive management mode, aiming at fitting an index, which has the characteristics of both stocks and index funds.
