FWIW for my comment I essentially used your code and cleaned up compiler-generated imperative code. So yes it used the fact that it only recursed to n-1 but did not use any optimizations related to booleans. And looking at other examples ca

Ah cool, are the internalized orders reported publicly anywhere or are they just sent to the SEC/FINRA?
