The MA moving average, most people probably only know that it is related to price, but it also serves as support and resistance. More importantly, when the candle rises to a certain height, if the moving average is too far from the candle, no one will step in to buy, so the big players can only sell off and push back down to the lower moving average. The moving average also has a magnetic effect; when the moving average is too high, it reaches a certain level, and the room for upward movement is limited, reducing the supporting effect of the moving average. Conversely, when it falls below the moving average, the moving average has the function of quickly falling back down. It's like an egg; dropping from the third floor versus the fifth floor has different impacts on your head. The candles below the moving average can also drop quickly. This wave of Bitcoin has strayed too far from the moving average, hoping for a pullback so that everyone short and long can make some money to go home for the New Year.
