Resumo

Princípio

- b = (y) /n - m ((x) /n

Vantagens

Análise de riscos

Os principais riscos desta estratégia são:

Os resultados dos backtests são aparentemente muito bons, mas os efeitos práticos são decepcionantes.

Orientações de otimização

A estratégia pode ser ainda melhorada nos seguintes aspectos:
