通过均线和MACD来判断未来趋势，然后自动下单，只能抓取第二波和第三波趋势，第一波因为价格变动不一定正确，所以只抓取第二波和第三波。(The future trend is judged by the equalization and MACD, and then the second and third wave trends can only be captured. The first wave is not necessarily correct because of the price change, so only second and third waves are captured.)
