O Gap Overnight opera na abertura quando o preço apresenta um gap significativo em relação ao fechamento anterior devido a notícias ou atividade fora do horário.
Grandes gaps frequentemente recuam parcialmente à medida que os traders digerem o movimento.
Os testes indicam um retorno anual médio de aproximadamente 124%. Funciona melhor no mercado de forex.
A estratégia vai contra gaps excessivos, entrando na direção oposta logo após a abertura e fechando antes do fim da sessão.
Os stops são baseados em um percentual além dos extremos do gap para gerenciar o risco caso o movimento continue.
Detalhes
Critérios de entrada: sinal de indicador
Comprado/Vendido: Ambos
Critérios de saída: stop-loss ou sinal oposto
Stops: Sim, baseado em percentual
Valores padrão:
CandleType = 15 minute
StopLossPercent = 2
MinGapPercent = 0.01
O mercado negocia 24 horas, por isso a sessão é o dia UTC. O gap é a distância entre o último fechamento do dia anterior e a primeira abertura do dia. Um gap de pelo menos MinGapPercent é operado contra no fechamento do primeiro candle; o stop fica StopLossPercent além da máxima (venda) ou da mínima (compra) desse candle e é verificado nos fechamentos, e a posição é encerrada no último candle do dia.
