19.随机指数(KDJ);它是综合移动平均数,相对强弱指数和威廉指数的特点而形成的一种技术分析方法。(1)KDJ指标的计算方法:①计算n日内(通常短期选用6日或9日)的相对强弱值RSV:②计算K(%)值,公式为:K1=αRSVt+(1—α)Kt-1α为平滑系数,一般取。上述公式得到
19. Stochastic Index (KDJ); It is a technical analysis method formed by combining the characteristics of moving average, relative strength index and William index. (1) Calculation method of KDJ index: ① Calculate the relative strength RSV within n days (usually short-term 6 or 9 days): Calculate K (%), the formula is: K1 = αRSVt + (1-α) Kt -1α for the smoothing coefficient, generally take. The above formula is obtained
