Retrieve information from a Web page, and put it inside my own MT4 Expert Advisor

The task will be use some MQL4 coding to retrieve the numeric data of correlation that appears in this Web page: https://www.mataf.net/es/forex/tools/correlation (is the table of 28 currency pairs that is colored in greens and reds).

This MQL4 coding I will put inside my own MQL4 Expert Advisor (I'm intermediate level for the EA coding).

In the web page, for retrieving the information "Mostrar un valor de correlación promedio" ("Show an average correlation value"), one must to do click in the "Actualizar" ("Update") button.

Thank you.
