Estratégia lógica

Esta estratégia determina a direção da tendência a longo prazo, analisando a direcionalidade de várias médias móveis.

A lógica é:

  1. Calcular médias móveis de períodos diferentes, por exemplo, de 5 dias, 20 dias, 50 dias, etc.

  2. Comparar a tendência direccional dos MA para determinar um alinhamento consistente

  3. Quando os MAs estão a subir uniformemente, mantém-se uma visão de alta a longo prazo.

  4. Em condições de alta, as rupturas acima do ponto de paragem de queda desencadeiam entradas longas

  5. Em condições de baixa, os breakouts abaixo do ponto de stop loss ascendente desencadeiam entradas curtas.

  6. As paradas de atraso são utilizadas para controlar o risco

A estratégia enfatiza a confirmação da tendência a longo prazo antes da negociação para reduzir o risco não sistemático.

Vantagens

  • Múltiplas AD se combinam para avaliar a direcção da tendência a longo prazo

  • As entradas de ruptura seguem a tendência

  • A estratégia de trailing stop controla o risco

Riscos

  • Os próprios MAs estão atrasados em termos de preços

  • A avaliação incorreta da tendência pode conduzir a perdas sustentadas

  • Longo ou curto só perde oportunidades

Resumo

Esta estratégia enfatiza a determinação da tendência secular através da direcionalidade da MA para minimizar os riscos não sistemáticos.
