通达信指标微积分RSI预测股市涨跌学会它从此告别韭菜命运！

指标简述

相对强弱指数（RSI）是由J. Welles Wilder在1978年开发的一种动量振荡器，用于衡量价格变动的速度和变化，帮助识别超买和超卖的市场条件。RSI的计算基于一定时期内上涨日和下跌日的平均收益和损失。通常，RSI值高于70被视为超买信号，可能预示价格继续上涨；而RSI值低于30则被视为超卖信号，预示继续下跌。RSI的计算公式为：

平均下跌平均上涨

其中，平均上涨和平均下跌是一定时期内上涨和下跌幅度的平均值。常见的RSI周期为14天，但也可以根据交易策略调整。

此外，RSI还可以用于识别背离现象，即价格创新高或新低，而RSI未能确认，这通常是趋势反转的信号。RSI的背离分为正背离（ bullish divergence）和负背离（bearish divergence），分别预示上涨和下跌。
