外汇中的RSI是什么？
相对强弱技术指标(RSI)是追踪价格的震荡指标，其取值范围为0到100。RSI由怀尔德发明，他建议使用14日RSI。随着时间变化9日和25日的相对强弱指标变得流行起来。一种分析RSI的流行方法是寻找背离：当价格形成新高时RSI无法穿越前期高点。这种背离是反转即将发生的指示。如果相对强弱指标转向下行并跌破最近的低谷，代表着RSI已经完成了一次“失败反转”。失败反转是对即将发生的反转的确认。
相对强弱指标的下列方面十分独特：
顶与底 相对强弱指标常常高于70或者低于30。它们通常早于价格图形成顶和底；
图形 RSI经常形成价格图上可能看不到的图形，例如头和肩或三角；
失败反转(突破或穿透支撑位或阻止位)此时相对强弱指标超越前一峰位或跌破前一低谷；
支撑和阻止水平 比起价格图，支撑和阻止水平可以在相对强弱指标图上更好地看到。
背离 当价格形成新高(或新低)但相对强弱指标图没有相应的新高(或新低)即为背离。价格通常会修正并沿着RSI的方向变化。
计算
RSI = 100-(100/(1+U/D))
其中：
U - 价格正向变化的平均数；
D - 价格负向变化的平均数。
