Reading RSS News Feeds by Means of MQL4

This article deals with an example of reading RSS markup by means of MQL4 using the functions for HTML tags analysis. We will try to make a work piece which can then be turned into a news indicator or just an RSS reader on MQL4 language.

Even if it's possible it would result in a large gap in the chart (between those hours), since the time axis is fixed (only scaling can be changed). I am guessing u don't want that...

Option one is to use offline charts and remove the periods. Search for Constant Range Bars and Renko Charts.

Option two is to simply draw a rectangle over the area
