SuperTrend历史回测与实时/复盘结果不一致问题求助

问题描述 #

• 基于SuperTrend开发的策略，历史回测表现优异，但实时图表或Replay Tool复盘时表现极差，核心逻辑为：SuperTrend显示上涨趋势开多单，下跌趋势开空单
• 测试条件完全一致：3m图表，SuperTrend时间框架设为30m，ATR长度1，Factor1；RRR1.5，止损为前一波段高低点，测试时段均为11月4日
• 核心差异：复盘时SuperTrend趋势切换频率远高于历史回测，胜率和收益数据差距极大

已排查与临时方案 #

• 发现部分问题源于security()函数默认启用barmerge.lookahead_on（未来数据引用），改为barmerge.lookahead_off后差异减小，但未完全解决
• 临时方案：添加趋势切换阈值，待突破反向趋势X%后再确认切换，但未彻底解决问题，寻求彻底解决方案
