MACD, also known as convergence and divergence of moving averages, is developed from double moving averages. Slow moving average minus fast moving average. The meaning of MACD is basically the same as the double moving average, but it is easier to read. When MACD turns from negative to positive, it is a buy signal. When MACD turns from positive to negative, it is a signal to sell. When the MACD changes at a large angle, it means that the gap between the fast moving average and the slow moving average expands very quickly, which represents the change of the market trend.

Stochastic index (KDJ index's Chinese name is stochastics) originated in the futures market and was initiated by george ryan. It reflects the strength of the price trend through the fluctuation range of the highest price, lowest price and closing price of the day or in recent days. There are three lines on the graph for stochastic indicators, namely, K line, D line and J line. The meaning of random indicator KD line: KD line is called random indicator, K is fast indicator and D is slow indicator. When K line breaks through D line, it indicates an upward trend and can be bought; K-line can be sold when it breaks through D-line, KD value rises above 90 to represent high, and below 20 to represent low. If it is too high, there is a possibility of falling, and if it is too low, there is a chance of rising. K value = 2/3× K value of the previous day +65438+ 0/3× RSV D value of the current day = 2/3× D value of the previous day +65438+ 0/3× K value of the current day = 3* K value of the current day-2* D value of the current day.
