概述
该策略结合多时间框架的多空停板,在会话时间段内捕捉短线突破进行扩散交易。属于短线扩散类策略。
策略原理
计算当日和短期的多空中轨,形成两个时间框架下的突破口。
仅在自定义的交易时段内进行交易。时段开始进入突破口,时段结束平仓。
计算价格实时EMA作为入场价格。价格超过中轨则产生突破信号。
设置突破口外的止损线。突破失效时止损。
当价格回落到中轨附近时,确认突破失败而平仓。
优势分析
结合多时间框架,可以有效过滤假突破。
限定交易时段可以避开重要新闻事件。
EMA跟踪价格可以顺势而为,及时入场。
设置止损线有助于控制风险。
按时段强制平仓可以避免过夜风险。
风险分析
短线突破可能出现止损被触发的情况。
部分突破可能在时段结束前无法完整获利。
时段设置不当也可能错过交易机会。
不能保证每次突破都能达到预期获利。
优化参数时可能存在过拟合问题。
优化方向
测试不同突破参数找到最优组合。
评估其他指标来提高入场的准确性。
优化交易时段,在盈利和风险之间寻找平衡。
研究如何搭配止盈策略来锁定利润。
测试不同品种参数设置的差异性。
采用机器学习算法动态优化参数。
总结
该策略试图通过限定会话突破来进行短线扩散交易。针对假突破和风险控制方面进行优化,可以将其改进为一个务实高效的短线交易策略。
