本策略运用快速RSI指标识别超买超卖现象,进行反转交易。该策略同时结合K线实体大小滤波,避免被卡住。策略追求快速判断超买超卖现象,及时捕捉反转机会。
策略原理:
计算快速RSI指标值,设置超买超卖阈值。
计算K线实体大小的EMA均值,判断实体大小。
RSI上穿超买线且实体大于均值一半时做多。RSI下穿超卖线且实体大于均值一半时做空。
RSI回穿原阈值线且实体大于均值时平仓。
还可结合最小值最大值进行额外验证。
该策略的优势:
快速RSI判断超买超卖迅速,避免滞后。
实体大小滤波可跳过不明显的K线。
最小值最大值验证可提高信号质量。
该策略的风险:
实体大小滤波可能过滤掉部分有效信号。
RSI对震荡行情中可能出现假信号。
需严格资金管理,应对反转交易的风险。
总之,该策略利用快速RSI与K线实体大小指标进行组合交易,在快速判断超买超卖的同时进行风险控制,可获得较佳效果。但需警惕过滤的问题,同时部署好资金管理手段。
