以日CCI计算为例,其计算方法有两种。
第一种计算过程如下:
CCI(N日)=(TP-MA)÷MD÷0.015
其中,TP=(最高价+最低价+收盘价)÷3
MA=最近N日收盘价的累计之和÷N
MD=最近N日(MA-收盘价)的累计之和÷N
0.015为计算系数,N为计算周期
我把N设为14,以000001深发展A为例,数据如下,我自己计算出来的CCI与行情软件上显示的CCI相差很大:
| 日期 | 最高价 | 最低价 | 收盘价 | TP | MA | MA-收盘价 | MD | CCI | 行情软件上CCI | | 2011/8/4 | 17.2 | 16.87 | 16.89 | 16.9867 | 17.2021 | 0.3121 | 0.1787 | -80.36 | -67.9 | | 2011/8/3 | 17.08 | 16.72 | 16.86 | 16.8867 | 17.2807 | 0.4207 | 0.107 | -245.48 | -100.74 | | 2011/8/2 | 17.12 | 16.73 | 17 | 16.95 | 17.3321 | 0.3321 | 0.0522 | -487.99 | -96.4 | | 2011/8/1 | 17.52 | 16.98 | 17.2 | 17.2333 | 17.3707 | 0.1707 | | | | | 2011/7/29 | 17.75 | 16.7 | 17.34 | 17.2633 | 17.3564 | 0.0164 | | | | | 2011/7/28 | 17.02 | 16.72 | 16.85 | 16.8633 | 17.3607 | 0.5107 | | | | | 2011/7/27 | 17.34 | 17.02 | 17.18 | 17.18 | 17.4086 | 0.2286 | | | | | 2011/7/26 | 17.3 | 16.8 | 17.23 | 17.11 | 17.4164 | 0.1864 | | | | | 2011/7/25 | 17.26 | 16.75 | 16.87 | 16.96 | 17.4171 | 0.5471 | | | | | 2011/7/22 | 17.45 | 17.15 | 17.21 | 17.27 | 17.455 | 0.245 | | | | | 2011/7/21 | 17.56 | 17.17 | 17.18 | 17.3033 | 17.4793 | 0.2993 | | | | | 2011/7/20 | 17.74 | 17.38 | 17.54 | 17.5533 | 17.4614 | -0.0786 | | | | | 2011/7/19 | 17.76 | 17.48 | 17.54 | 17.5933 | 17.4279 | -0.1121 | | | | | 2011/7/18 | 18.13 | 17.79 | 17.94 | 17.9533 | 17.3629 | -0.5771 | | | | | 2011/7/15 | 18.2 | 17.39 | 17.99 | 17.86 | 17.2986 | -0.6914 | | | | | 2011/7/14 | 17.65 | 17.38 | 17.58 | 17.53667 | 17.2343 | -0.3457 | | | | | 2011/7/13 | 17.72 | 17.13 | 17.54 | 17.4633 | | | | | | | 2011/7/12 | 17.28 | 16.94 | 17 | 17.0733 | | | | | | | 2011/7/11 | 17.63 | 17.35 | 17.4 | 17.46 | | | | | | | 2011/7/8 | 17.8 | 17.22 | 17.52 | 17.5133 | | | | | | | 2011/7/7 | 17.63 | 17.14 | 17.29 | 17.3533 | | | | | | | 2011/7/6 | 17.37 | 17.05 | 17.24 | 17.22 | | | | | | | 2011/7/5 | 17.53 | 17.28 | 17.4 | 17.4033 | | | | | | | 2011/7/4 | 17.56 | 16.97 | 17.55 | 17.36 | | | | | | | 2011/7/1 | 17.15 | 16.83 | 16.93 | 16.97 | | | | | | | 2011/6/30 | 17.21 | 16.67 | 17.07 | 16.9833 | | | | | | | 2011/6/29 | 17.17 | 16.58 | 16.63 | 16.7933 | | | | | | | 2011/6/28 | 17.4 | 16.79 | 17.04 | 17.0767 | | | | | | | 2011/6/27 | 17.53 | 16.93 | 17.09 | 17.1833 | | | | | |
2011/8/4 MA=(16.89+16.86+17+17.2+17.34+16.85+17.18+17.23+16.87+17.21+17.18+17.54+17.54+17.94)/14=17.2021
2011/8/4 MD=(0.3121+0.4207+0.3321+0.1707+0.0164+0.5107+0.2286+0.1864+0.5471+0.245+0.2993+(-0.0786)+(-0.1121)+(-0.5771))/14=0.1787
2011/8/4 CCI(14日)=(TP-MA)÷MD÷0.015=(16.9867-17.2021)÷0.1787÷0.015= -80.36
8月3日和2日的计算方法依此类推,
但计算出来的CCI与行情软件上14的CCI相差很大,请问是不是我的计算方法不对?
谢谢! |
