It seems probable from your initial post: are the rules in your in your strategy transparent and reproducible by anyone with even superficial markets knowledge? Is there an input in the process that is calculated separately, e.g. a ratio value, that you needn't declare in the main script? Is the broad strategy based on a market behaviour or artefact that is well-known?
You might consider hiring a programmer through a medium such as Upworker to code your rules. Depending on your answers to the above, this isn't necessarily risky as it might sound. I've had an R package written from the rules in an academic paper (I did get a NDA signed) by someone who was highly competetent in R and statistics, but was unlikely to be interested in implementing. Yes, it does require care in selecting your freelancer.
Once upon a time in my own community I found someone with very good C++ (and signal-processing knowledge) to automate a fairly simple rules-based FX strat for the IB API. We ended up collaborating and in fact he improved the strategy.
