Esta estratégia utiliza o indicador Rate of Change (ROC) para determinar a direção do mercado e gerar sinais de negociação.
Quando o stop loss é acionado, a posição é invertida, o que indica que podemos estar no lado errado do mercado, por isso saímos imediatamente.
Se o ROC ultrapassar 200, o mercado é considerado uma bolha. Quando o ROC cai abaixo do território da bolha, o sinal de curto prazo é ativado.
Usar o tamanho de posição fixa + método incremental. Aumentar / diminuir a posição em US $ 200 para cada US $ 400 de ganho / perda. Isso nos permite obter lucros em pirâmide, mas também aumenta o drawdown.
Vantagens desta estratégia:
Existem também alguns riscos:
Algumas maneiras de otimizar a estratégia:
Em resumo, esta é uma tendência de longo prazo seguindo uma estratégia centrada em torno do indicador ROC. O objetivo é gerar alfa assumindo um risco maior.
