🎯 策略核心亮点：不只是看价格的EMA策略
你知道吗？大部分人用EMA只会看价格，但这个策略厉害在哪？它能从6种不同数据源计算EMA！就像做菜不只用盐调味，还能用糖、醋、酱油一样，给你更丰富的交易信号。
划重点！这6种数据源包括：普通价格、成交量、变化率、平均K线价格、平均K线成交量、平均K线变化率。每种都有不同的市场洞察力！
📊 三重过滤系统：让信号更精准
这个策略不是随便给信号的！它有三道”安检”：
第一道：EMA趋势判断 📈 就像看天气预报，先确定大方向是晴是雨
第二道：ADX强度过滤 💪
ADX就像测量风力的仪器，只有趋势够强（默认25以上），才发出信号。避免在震荡市中被来回打脸！
第三道：成交量确认 🔊 成交量突增就像股票在”大声说话”，证明这个信号是认真的，不是开玩笑
🎮 三种退出模式：适应不同交易风格
最贴心的是，这个策略给了3种退出方式，就像游戏有简单、普通、困难三个难度：
模式1：反向信号退出 🔄 最简单粗暴，多头信号来了就平空开多，空头信号来了就平多开空
模式2：ATR动态止盈止损 📏 根据市场波动性自动调整，波动大的时候止损放宽点，波动小的时候收紧点
模式3：固定百分比止盈止损 📊 最好理解，赚2%就跑，亏1.5%就认输（可自定义）
🚀 实战应用建议
适用周期：中短期交易，特别适合有一定波动性的市场 避坑指南：震荡市要小心，建议开启ADX过滤 进阶玩法：可以尝试不同数据源，成交量源在放量突破时特别有效！
这个策略最大的优势就是灵活性强，你可以根据不同市场环境选择最合适的数据源和退出模式。记住，没有完美的策略，只有最适合当前市场的策略！
