manual installing an app as standard PortableApps

I am trying installing MT4 as standard PortableApps, since to clear documentation I used AI to figure out how to implement structure and in related installation files, I almost did most part of the structure used, note that with /portable we can run mt4 as portable, I intentionally had moved some common files to a common folder using
so the steps were :
1. moving common folder so we can use them linked,
2 create the ini files so that portable app can proper list and categorise the terminals
3. (Missing part) creating the exe file that would call actual exe
Any idea please let me know
