No, the existence of any index is reasonable, and any index has two sides. The only way to profit from the index alone is to find the index and get the interest rate. For example, MACD, if there are all kinds of gold forks in a simple MACD, I estimate that what you are doing is a loss, because even a simple gold fork will have different results according to different cycles. Maybe the accuracy of MACD gold fork on the weekly line of a commodity is a numerical value, and the same commodity will become another numerical value within a 3-minute cycle. There is no necessary connection between the two. MACD is calculated according to the prices that have occurred in the market, and the market is random, so the probability distribution of MACD results is also random. But if the distribution is combined with the probability characteristics of indicators, it may be very different. Send me a probability diagram of the rising cycle, and you will understand.

In a certain period in the past, the volume of this transaction was greater than a certain scale+when the periodic price was greater than the 5-day average price, then in the next trading cycle, it must be greater than the highest price in a week for 9 times. This combination feature is 9 times, and the accuracy can be said as 100%.

Any simple indicator, such as trading volume and moving average, has a detailed use method, but this method may not make you profitable, but finding a high probability combination between them may have completely different effects.
