Estratégia de Fraqueza Pós-Feriado
A Fraqueza Pós-Feriado é a tendência dos preços caírem imediatamente após um grande feriado quando o volume permanece baixo.
Com muitos participantes ainda ausentes, movimentos contra a tendência podem ganhar força.
Os testes indicam um retorno anual médio de aproximadamente 112%. Funciona melhor no mercado de forex.
A estratégia vende a descoberto no dia seguinte ao feriado e cobre rapidamente assim que a participação normal retorna.
Um stop pequeno é usado para evitar perdas excessivas durante a negociação com baixa liquidez.
Detalhes
- Critérios de entrada: ativadores de efeito de calendário
- Comprado/Vendido: Ambos
- Critérios de saída: stop-loss ou sinal oposto
- Stops: Sim, baseado em percentual
- Valores padrão:
CandleType = 15 minute
Holidays = 2024 NYSE holidays
StopLossPercent = 2
Os dias são dias UTC, pois o mercado negocia 24 horas; as entradas ocorrem no fechamento da primeira vela do dia. Holidays é uma lista de datas yyyy-MM-dd separadas por vírgula, por padrão os feriados da NYSE de 2024 (a Sexta-feira Santa é 2024-03-29). O mercado negocia todos os dias, então a venda a descoberto abre no dia corrido seguinte a um feriado e é coberta na última vela desse dia.
