"Tested live"? Which in financial parlance means "unprofitable". Else why would you give it away? Anyone doing a simple google search can find dozens if not more spread trading algos that developers can peruse free of charge. Maybe you meant to say you have a C# hook into Rithmic's API?
Programmers are a dime a dozen these days, profitable automated strategies with considerable high frequency, now that's a diamond in the rough. When you contact your coding team, make sure you leave many details to customization and do not divulge those parameters, I speak from experience. What's yours is yours to keep and yours only.
good programmers are not, and robust, stable strategy, whether high or low frequency, are even rarer.
No disrespect to any coder, but all it takes to get a good programmer is some modest cash and off you go. At my age, not necessarily a hard commodity to come by, the rest as you said, is a much more rare luxury. Just giving a warning about the sharing of all details, strategies should be guarded, even against your own programmer, NDA or no NDA; they are just too valuable.
agree with all other points but good programmers simply are not easy to find nor cheap. Someone who can push even a popular OOP language such as C# to the limits can absolutely command a high premium, and I am talking about > $200k per year salaries. Anyone who values himself less is either not good or junior and not experienced enough. But we may have different definitions of "good".
