Depois de encontrar uma enorme quantidade de uso do usuário de TVs wugamlo script Order Block Finder (Experimental), eu decidi fazer algumas atualizações muito necessárias! Adicionou suporte para traçar o último número X de blocos de ordem e estou atualmente trabalhando em uma versão de timeframe múltipla.

Se você quiser contribuir para a parte de análise MTF, que beneficiaria toneladas de outros scripts e abrir a possibilidade de mais indicadores de estilo MTF Panel.

Por favor, visite a página do script original (link no topo) para rever como o indicador é usado na negociação.
