Estratégia de Índice de Percentual Altista do Bitcoin

Esta estratégia usa o Índice de Força Relativa (RSI) para aproximar o Índice de Percentual Altista do Bitcoin. Entra comprado quando o RSI sobe acima do nível de sobrevenda e entra vendido quando o RSI cai abaixo do nível de sobrecompra.

Detalhes

  • Critérios de entrada:
    • Comprado: RSI cruza acima do nível de sobrevenda.
    • Vendido: RSI cruza abaixo do nível de sobrecompra.
  • Comprado/Vendido: Ambos.
  • Critérios de saída: Sinal oposto.
  • Stops: Não.
  • Valores padrão:
    • RSI Period = 14
    • Overbought = 70
    • Oversold = 30
  • Filtros:
    • Categoria: Oscilador
    • Direção: Ambos
    • Indicadores: RSI
    • Stops: Não
    • Complexidade: Baixo
    • Período: Médio prazo
