该策略使用两条指数移动平均线(EMA)的交叉作为买卖信号。当较短周期EMA从下向上穿过较长周期EMA时,产生买入信号;反之,当较短周期EMA从上向下穿过较长周期EMA时,产生卖出信号。同时,该策略还会判断交叉点是否是最近10个交易周期内的最高价或最低价,以此来确认趋势的强度。如果交叉点是最高价,则会在背景上显示绿色;如果是最低价,则会显示红色。此外,该策略还会在图表上显示交叉点的价格。
该策略以指数移动平均线交叉作为核心逻辑,同时结合交叉点价格在近期的相对位置,以判断趋势强度。整体而言,策略逻辑清晰,优势明显,但也存在一定局限性和风险。通过引入更多辅助判断指标,设置合理的风控措施,优化关键参数,可以进一步提升该策略的稳定性和盈利能力。
