Estratégia Three White Soldiers
O padrão Três Soldados Brancos é uma reversão de alta clássica composta por três velas de alta fortes consecutivas. Após uma tendência de baixa, essa sequência frequentemente marca o início de um movimento ascendente sustentado, pois a pressão compradora supera os vendedores.
Os testes indicam um retorno anual médio de aproximadamente 175%. Funciona melhor no mercado de ações.
A estratégia entra comprada assim que o terceiro soldado se forma, esperando continuação do aumento de momentum. Operações vendidas não são realizadas porque o setup é puramente de alta, mas o sistema permite encerrar posições vendidas iniciadas por outros métodos.
Os stops são colocados a uma pequena distância abaixo do padrão para proteger contra sinais falsos, e as posições encerram se o preço fechar novamente abaixo desse nível.
