Estratégia de Equilíbrio de Forças
A estratégia de Equilíbrio de Forças avalia a força dos touros versus os ursos dentro de cada vela comparando o fechamento com o intervalo de negociação. Quando este valor cruza acima de um limiar positivo, indica forte pressão compradora.
A estratégia entra em uma posição comprada quando o Balance of Power cruza acima do Threshold definido e sai quando cai abaixo do limiar negativo.
