本策略融合韦氏波浪指标和布林带指标,判断市场趋势方向,并在关键 SUPPORT 位进行突破交易。属于典型的趋势突破策略。
策略原理:
计算韦氏波浪,通过柱状图走势判断价格趋势。
计算布林带上下轨,并当价格突破轨道时进入场内。
当韦氏波浪显示多头趋势,价格突破布林带上轨时做多。
当韦氏波浪显示空头趋势,价格突破布林带下轨时做空。
在反向趋势出现时设置止盈止损退出场内头寸。
该策略的优势:
韦氏波浪指标可有效判断主要趋势方向。
布林带可发现关键的 SUPPORT 阻力位。
组合使用指标,可提高判断准确性。
该策略的风险:
韦氏波浪和布林带均存在滞后问题,入场点位不佳。
突破交易容易被套,需要止损保护。
震荡行情中难以发现持续趋势和明确突破点。
总之,该策略融合韦氏波浪和布林带判断趋势方向,在关键点位进行突破交易。能在一定程度上提高准确性,但需警惕滞后及震荡市的问题。
