Hey @mattfair! Welcome to Lean 🚀
Leaving a few requests, the biggest is trying to simplify the implementation a bit, simpler always 10x better.
Also something that's missing from this PR is the helper method in QCAlgorithm.Indicators.cs, there are plenty merged indicator PRs to take a look at for this 👍
