Create from scratch OR convert Sierra Chart indicator Cumulative Delta Bars (Up/Down Tick Volume) (C++) to MQL4 for MT4

Like the title says, I need someone to create from scratch or convert Sierra Chart indicator Cumulative Delta Bars (Up/Down Tick Volume) which is in C++ to MQL4 for MT4. The person obviously needs to be very good in C++ if they choose to convert it. Here is the reference page: https://www.sierrachart.com/index.php?page=doc/StudiesReference.php&ID=323&Name=Cumulative_Delta_Bars_-_Up_Down_Tick_Volume. Source code is attached. I consulted with an expert about this project and here are some important things that he told me:

• You will need to check if the code makes calls to Sierra's function library, which of course won't exist in mql4.
• The function library includes a lot of pre-compiled routines for common tasks to avoid having to code them yourself. Most languages provide them, but of course a Sierra function call won't mean anything to the mql4 compiler.
• The function library is in a file called sierrachart.h
• The Sierra library is designed to run in a C++ environment. What you need to do is convert the source code for the Sierra functions into mql4 and then compile them in the mt4 environment.
• You'll find that within sierrachart.h, there are calls to other libraries as well.  I haven't checked the function calls used for the Cum Delta study, so it may be code that you can just lift, convert and compile.  On the other hand you may have to search a few other libraries to get all of the code needed. Your best bet is to find someone who knows both Sierra and mql4 and then they can translate directly.
