Some adjustments to an almost complete EA, utilizing visual display function on chart

Hi, 

This should be a quickie:

I had a friend/coder try to create an EA that would serve as a tracker display tool {it is in the form of an EA, although an indicator is typically used for this purpose, and EITHER EA or indicator would work, but anyways, in this case it was built as an EA}. 

The Levels Tracker, as I call it, based on a strategy called the Levels Technique, is intended to track whether a trade, based on 2 sample points, was a winner or a loser given EA input settings. The EA uses candle ID to assess the sample points, and has a unique way of calculating winner or loser. It also has the capacity to assess winner or loser incorporating a spread. 

The issue we need to fix is that currently, the EA looks at multiple currencies internally {even if the charts are not loaded}, but I need it simplified such that it looks at ONE chart at a time {as normal with any other EA}.  

The EA is intermediate level complexity, note that the EA was originally built for other purposes, but we just need to focus on the applicable functions and pinpoint the alteration we are looking for. 

A quick 45 minute skype meet would be required in order to gain a clear and comprehensive grasp of the complete project and its parameters, and to navigate through the already built code.
