Reading the Code and translating the Mq4 Code into plain understandable English.

I have a two parts project deal; This task is only for the 1st Part: 

1) Read MQ4 code and translate it into plain English. Or in other words describe me the strategy used in the Code. 

- Translate the code in plain English as what every line of code is doing. 

 (a lot of indicators and functions are not being called) - and highlight the codes that are there but are not being used. 

- EA is using History Data using DLL to look back at data / look forward into data (?), how can we replace this so that EA uses a normal indicator to read History Data. 

- What calculations are hard coded into the EA. 

- What are all the Entry conditions and what are all the exit conditions?
