Esta é uma estratégia de rastreamento de tendências baseada no Average True Range (ATR). Ele usa o ATR para calcular os valores do indicador e determinar a direção da tendência de preços.
A estratégia utiliza três parâmetros principais: período, multiplicador e ponto de entrada/saída.
A estratégia calcula primeiro o preço médio longo (buyvg) e o preço médio curto (sellavg), em seguida, compara a relação de preços entre essas duas médias para determinar a direção da tendência atual.
Além disso, a estratégia incorpora o ATR para definir um stop loss final. Especificamente, ele usa a média móvel ponderada de 14 períodos do ATR multiplicada por um multiplicador (padrão 4) como a distância de stop loss. Isso permite que a distância de stop loss seja ajustada com base na volatilidade do mercado.
Quando o stop loss é acionado, a estratégia fechará a posição para garantir lucros.
Em geral, esta é uma estratégia simples e prática de rastreamento de tendências. Ele só precisa de alguns parâmetros para implementar, e usa ATR para ajustar dinamicamente paradas para controlar efetivamente os riscos. Quando combinado com outros indicadores de assistência para filtragem, ele pode ser ainda mais otimizado.
