Este é um redesenho do indicador parabólico SAR incorporado. Eu adicionei um sistema de entrada adequado, uma opção para destacar pontos iniciais para ambas as linhas e uma opção para escolher largura de pontos.
O SAR parabólico foi originalmente desenvolvido por J. Welles Wilder e descrito em seu livro
Para saber quais as configurações para PSAR são os mais rentáveis em seu instrumento e prazo você pode usar esta ferramenta
