Days have to be divided by 6 as usual. xM3 is unusual, 78/6 = 13 times in 8 years. x33 is favorable to buy and x03 is not. Note how xF3 and xM3 are less volatile (CH and CL are smaller than x03 and x33). I’ve been critical of the standard statistical volatility measures because they are so idiotic.
