Estratégia de Reversão Um-Dois-Três
A estratégia de Reversão Um-Dois-Três procura um padrão altista 1-2-3 na ação do preço. Uma posição comprada é aberta quando a mínima de hoje está abaixo da de ontem, a mínima de ontem está abaixo da mínima de três barras atrás, a mínima de duas barras atrás está abaixo da mínima de quatro barras atrás, e a máxima de duas barras atrás está abaixo da máxima de três barras atrás. A operação é encerrada após um número definido de barras ou quando o preço fecha acima de uma média móvel.
