From observation to rule
specification
Turning an observation into a rule means removing every judgement it contains until a second person would act identically. Each unstated choice - which swing counts, how close is close enough, what happens when two conditions conflict - is a place where your results and theirs will diverge, and a place where a backtest silently substitutes its own answer.
This lesson is part of the advanced modules.
Modules 6 to 8 are included with a paid account. The definitional summary above is the whole of this page until then.
