例句 Examples

我在买入股票前会查看相对强弱指数。

When the relative strength index diverges from price, some traders treat it as an early sign that momentum is weakening, though it’s not a guarantee of reversal.
当相对强弱指数与价格走势出现背离时,有些交易者会把它视为动能减弱的早期信号,但这并不保证趋势一定反转。

词源 Etymology

该术语由三部分构成:relative(“相对的”)+ strength(“强度/力度”)+ index(“指数/指标”)。在技术分析语境中,“relative strength”强调的是上涨与下跌动量的对比;RSI 这一指标由美国工程师兼交易系统研究者 J. Welles Wilder Jr. 在 1970 年代推广并系统化。
