Here are some references for you:
Trend indicators can be judged by a set of moving averages (MA). Short-term moving averages MA 10 and MA20, long-term moving averages MA60, MA 100 and MA200 can be comprehensively judged to determine the current trend.
When the long-term moving average suppresses the price and turns head down, it is generally believed that the market can be short when it is short, but it is safe to wait for the callback to encounter resistance. vice versa
The shock indicators can be judged by MACD and RSI, and always pay attention to the overbought/oversold tips of RSI to avoid the risk of quilt cover. MACD and RSI can also be used to judge the deviation of the market, thus confirming the formation of the reversal.
Hope to adopt, you can ask if you don't understand.
