A estratégia Gunbot Bands é uma estratégia de negociação algorítmica de análise técnica que visa acompanhar tendências e cortar perdas.
Como funciona
A estratégia entra em posições longas quando o preço fecha abaixo da banda de Bollinger inferior e posições curtas quando o preço fecha acima da banda de Bollinger superior. As bandas fornecem níveis dinâmicos de suporte e resistência que se adaptam à volatilidade do mercado.
O tamanho da posição aumenta exponencialmente em sinais longos / curtos consecutivos, implementando um componente de martingale.
Benefícios
As principais vantagens desta estratégia são:
Riscos
Riscos potenciais a considerar:
