质量定量预测(QQE)指标的运作方式就像受欢迎的相对强弱指数(RSI)指标的平滑版。质量定量预测藉著加入两条以波动性为基础的移动止损线以在相对强弱指数的基础下进一步扩充。这些移动止损线由一条快及一条慢移动平均线真实波动幅度均值(Average True Range, ATR)平均真实区域 (ATR)所组成。这些ATR线被平滑化，使这个指标不易受到短期波动性所影响。 一个运用质量定量预测最普遍的方法，是在质量定量预测线反映出超买或超卖情况的期间寻找快及慢移动止损线的跨越情况。((Quality quantitative prediction (QQE indicator works like popular relative strength index (RSI) index smoothing. Quality quantitative prediction by joining the two based on the volatility of move the stop loss line in order to further expand under the basis of the relative strength index. These move the stop loss line by a fast and a slow moving Average real Average volatility (Average True Range, ATR) Average real area (ATR). The ATR line were smoothing, make this less susceptible to the short-term volatility. A quantitative prediction methods of the most common use quality is the quality of quantitative forecast line reflects an overbought or oversold condition during the search for fast and slow moving across the stop line. ))
