Can somebody explain inner workings of Hi-Lo.mq4 indicator?

[[Deleted]]

Hi,

I found a custom build MT4 indicator called the Hi-Lo.mq4 indicator. (The code for this indicator is included below.)

I want to use this indicator in a different platform, thus, I wish to decipher the mql code to understand the indicator. However, I have zero mql knowledge.

So I am looking for somebody who could look at the mql code and then explain to me in plain English, how the indicator works, what is it that it measures, how it calculates, how it determines whento plot above and when below the price, etc.

Any help will be highly appreciated.

Regards
