Have you thought about ways to objectively value your IP so you can make a good business decision about how to protect it? If you have strategies that cannot be traded without automation, I would think they have little (current) value to you and you have nothing but upside by having them automated by a competent programmer who may or may not violate your NDAs. In the end, though, it's up to you to come up with an estimate of how much it will cost you if the NDA is violated in differing ways so you know how much ROI you can expect from implementing different protection measures.
To reiterate some of the other posters, as a programmer I would seriously advise against trying to go from manual execution to 100% perfect automation in one step. You will get way more value from a good working prototype. You will find problems you couldn't have previously imagined and you will be in the game sooner to leverage your IP that is currently collecting dust at 10-100 times less cost.
