A ideia central desta estratégia é combinar o indicador Vix Fix e a sua regressão linear para capturar com precisão os fundos do mercado.
O processo acima utiliza regressão linear para melhorar a precisão e a puntualidade dos sinais Vix Fix, filtrando alguns sinais falsos e, assim, capturando com precisão os fundos.
Esta estratégia utiliza o indicador Vix Fix para julgar os fundos, ao mesmo tempo em que introduz a regressão linear para melhorar a qualidade do sinal, capturando efetivamente os fundos do mercado. A estratégia é simples, prática e produz resultados decentes. O principal risco está nos falsos sinais que não conseguem ser completamente filtrados. Ainda precisamos otimizar as configurações de parâmetros e considerar a introdução de outros meios para confirmar ainda mais os sinais para tornar a estratégia mais robusta.
