I.E. the algorithm never failed, or never made losing trades? That seems insane, to always be able to make money even if it's fractions of a percent.

This particular desk wasn't perfect - it had its ups and downs (there were definitely days where money was lost). Overall though it was profitable.

How does "very profitable" equate to "never made losing trades?" If you're only right 60% of the time you can still be profitable overall with proper risk management.
