该策略是一个基于指数移动平均线(EMA)交叉的趋势跟踪系统,结合了动态仓位管理和风险控制。策略使用快速与慢速EMA的交叉信号来识别市场趋势,同时通过百分比风险计算来动态调整交易规模,并采用移动止损来保护盈利。
策略的核心逻辑基于两条不同周期(默认为9和21)的指数移动平均线。当快速EMA向上穿越慢速EMA时,系统产生做多信号;当快速EMA向下穿越慢速EMA时,系统平仓。每笔交易的规模基于账户总资金的固定风险比例(默认1%)动态计算,同时设置了基于风险回报比的止盈水平和百分比移动止损。
这是一个将经典的技术分析方法与现代风险管理理念相结合的完整交易系统。策略通过动态仓位管理和移动止损来控制风险,同时利用EMA交叉捕捉趋势性机会。虽然存在一些固有的局限性,但通过建议的优化方向,可以进一步提升策略的稳健性和适应性。策略特别适合追求风险可控的长期趋势交易。
