Depends on if you have a mechanical strategy that works. I defined a mechanical strategy back in 2014 which I had written in MQL 4 and ran it live for some months to test it out before engaging with a number of beta testers.
The results have been good, my live account is up by triple digit % and some of my beta testers are up around 40-50% as well, the problem we found is that if there are too many options in the EA (Expert Adviser) then people will fiddle and then mess with their equity curve, so we have just had a new version written taking out a lot of the functionality and making it stick to the original mechanics of the strategy.
So in answer to your question it is possible, if you are looking to make some money you could rent your coding skills out?
