Trading experience Be careful when the bullish candlestick falls below, as it is the last line of defense for bulls. Once the trend is broken, it weakens. If there is another top deviation at a high level, and the price of the currency reaches a new high but the bullish line becomes shorter, then this bearish signal is more accurate. Breaking through the bearish candlestick is a good thing. When the bears are exhausted, breaking through the candlestick is when the bulls start working. Adding a bottom to the low and deviating from it, the price of the coin will hit a new low but the bearish candlestick will become shorter, so this bullish signal is more reliable. Adding one or two small bearish candlesticks to a bullish candlestick is called aerial refueling. It's just a wash off during the upward trend. Those who hold positions will increase their positions, while those who are short will get on board. A few small bearish candlesticks have emerged from the bearish candlestick, indicating a weak rebound during the downward trend. Don't enter. MACD dual line is underwater, no matter how high it rises, it should be viewed as a rebound first, without buying the bottom or participating. The real strategic opportunity is to cross the zero axis on both sides, which is called going ashore, and the trend may truly reverse. MACD has lag, don't just use it, We need to consider the K-line, moving average, and trading volume together. Deviation is the essence of MACD. Top deviation requires running, bottom deviation can be tried, and only when the position is correct can it be effective.
