Estratégia de Rompimento de Faixa ADX

Esta estratégia entra em posições compradas quando o fechamento rompe acima do fechamento mais alto de um período de retrospectiva enquanto o ADX permanece abaixo de um limiar especificado, indicando um mercado calmo. A negociação é limitada a uma sessão definida e a um número máximo de operações por dia. Um stop-loss fixo em unidades de preço protege cada posição.
