1, deviation, usually divided into top deviation and bottom deviation, indicates that the market trend is about to peak or bottom out. Almost all technical indicators have the function of deviating from the prompt, among which the technical indicators are MACD, RSI and CCI, which enable investors to use the deviation function of these indicators to predict the risk at the head and the buying opportunity at the bottom, but the time parameters should be appropriately extended.

2. The essence of deviation is that the strength of the line slows down. More specifically, the market trend is wave after wave, that is to say, the follow-up wave is more than wave, and the amplitude is smaller than wave. In other words, when a wave of bulls or bears are formed, with the deepening of the market, the strength of the market will gradually slow down, and of course the market will not always slow down unilaterally. Then when it slows down, the indicator will deviate. The essence of deviation is actually the slowdown of the market, in other words, the slowdown of the market will deviate.
