Overlay chart on top eachother using Vitrite program, must create custom .dll etc

I'm looking to overlay two charts from MT4 ontop eachother, so for example GBP/JPY and USD/JPY on top to see their correlation and cointegration. I have tried every indicator under the sun for overlays and ALL of them suffer from scaling issues/repaint and change over time. The only way not to suffer from this is to have two mt4 platforms open and use a program like vitrite and make one chart transparent so you can directly overlay it ontop of other mt4 chart.

 Need developer to make a program, indicator, .dll of some sort to make this process simple and so I can simply scroll through my charts on 1 mt4 with overlay connected from another.  PM me to talk in more detail.

 Don't apply if you are not extremely experienced.
