Transcript convert Ninjatrader 7 indicator to MT4 or MT5 indicator

Hy everyone,
It is the first time that I poste something on babypips so I do not know if it is the right place or not, please do no hesitate to correct me if I am wrong or to put the question in other place. First of all sorry for my English, I am not that good at it. My name is Jamal and I am from Spain but living in France. Well, it is really simple the question. I have an Indicator, the new version on Belkhayate’s gravity center (the new one is just awsome) on NT7 and I would use the same indicator on MT4 or MT5 or better, on tradingview. Well, I know that each platforme use s its own language to create indicators or EA and I perfectly know that it is not that easy to do. So if someone could do the job I have the source code and the indicator as well. Any idea?
Thanks
