Self Contained MQL4 code for Renko Bars

Hi,

I'm using iexpertadvisor.com to program my EA's.  I want to create a strategy with Renko Bars but that fonction isn't available yet in that software package. 

I need a specialist like you to program me the MQL4 code for renko bars because it's possible in iExpertAdvisor to include MQL elements in the development of an EA. 

One specification : The MQL function cannot rely on any global variable.  The MQL function should be completely self contained to produce Renko Bar in native MQL4 Language.   I also need to easilly be able change the brick size in the code. 

I would prefer a consultant that have already programmed with Renko bars.  It could be a very simple job but because I don't know how to program, I don't want to loose time and pick a MQL code in the internet and find after a lost of time that what I found is full of mistake and loose time and energy.  

We may have to adapt the code but technically, it should work fine, without any adaptation.  Finally, it will really be an asset if somebody have iExpertAdvisor to be able to test the function.
