How to use these

What we deliberately do not build

A profit projector defaulting to 20% monthly. Consistent traders target 1–3% per month. Compounded, 2% monthly is 26.8% a year — an extraordinary professional return, achieved by people who are deliberately boring.
A signal generator. Signals are the opposite of education.
A price prediction tool. Forecasting gold means forecasting the Fed's reaction to data that does not exist yet.
