很出名的交易系统，原理是利用价格超卖超买和最近最高最低价格来进行判断交易信号，同时再入场的信息也可以自己设置，我附上了源码，大家也可以在源码中增加自己的交易筛选信号提高正确率和盈利率。(Well-known trading system, the principle is to use price oversold and overbought and the latest highest and lowest price to judge the trading signal, while re-entry information can also be set by itself, I attached the source code, you can also add their own trading screening signal in the source code to improve the accuracy and profitability.)
