(6,3,3)、( 18,3,3)、(24,3,3)。 Because (6, 3, 3) is more sensitive to price fluctuations, it changes very frequently, which is suitable for short-term customers to find buying points and selling points. With (18.3,3) as the parameter, the signal is stable and the sensitivity is high, which is suitable for most situations. Taking (24,3.3) as the parameter can eliminate the false signal caused by price fluctuation to a greater extent, and it is a better choice to find the midline buying point or midline selling point of the price. Therefore, the optimal parameters of futures short-term kdj are (6,3,3), (18,3,3), (24,3,3). KDJ index, also called stochastics, is composed of three curves * * * of K line, D line and J line.
