red/green % retracement

[rcfc]

I can't make sense of the retracement % values I get from a red/green continuation scan.
Can you give me a specific example of how this is calculated?

For example, using February 19th's data, the retrace value here is 79% on a 10 day scan. How was the 79% calculated?
SHY 1-3 Year Treasury Bond Ishares 2/19/2016 84.96 Up -1% 79% Red Yes Yes 10 6 6 0 4 28 14 -1 84.90 85.18

It's calculated based off of the 10 day time period that you are using.

Low for the 10 day period: 84.9
High for the 10 day period: 85.18
Current Close: 84.96

Retrace = (HH - C)/(HH - LL)

Retrace = (85.18 - 84.96) / (85.18 - 84.9)
Retrace = 0.22 / .28 = 79%

Thanks Chris...confused the numerator with the denominator.
