Resumo

A estratégia de avanço de oscilação dupla VWAP analisa as tendências do mercado usando bandas duplas VWAP e procura oportunidades de avanço em mercados oscilantes.

Princípios de estratégia

A estratégia consiste nos seguintes componentes principais:

Configurações VWAP: Calcule as bandas VWAP e sua largura.stDevMultiplierA largura externa do VWAP é controladastDevMultiplier, por defeito para 2.
Configurações do ADX: Calcule os valores do ADX para determinar se o mercado está oscilando. O mercado é considerado oscilante quando o ADX está abaixo do limiar.
Configurações de entrada: Entre no mercado quando os preços atravessam as faixas externas do VWAP durante a oscilação.
Limites de entrada: EMA ou filtros de prazo opcionais para evitar a entrada durante períodos de tempo desfavoráveis.
Opção para sair quando os preços quebram as faixas externas do VWAP.

A estratégia identifica os mercados oscilantes usando o indicador ADX e procura oportunidades de entrada quando os preços quebram as bandas VWAP. As bandas duplas VWAP fornecem filtros adicionais para garantir fortes sinais de entrada.

Análise das vantagens

As bandas VWAP duplas fornecem filtros extras para sinais de entrada mais fortes.
O oscilador ADX identifica oscilações e evita entradas erradas durante tendências.
A paragem final bloqueia os lucros e impede que sejamos presos.
Parâmetros altamente configuráveis adaptados às diferentes condições do mercado.
A lógica simples torna fácil de entender, replicar e modificar.

Riscos e soluções

Otimizar as combinações de parâmetros para garantir a estabilidade da estratégia.
As paradas podem ser muito agressivas ou conservadoras, ajustando-se dinamicamente com base nos indicadores de volatilidade.
O desempenho depende muito das sessões de negociação.
A taxa de variação de preços é muito elevada, mas a taxa de variação de preços é muito baixa.

Orientações de otimização

Ajustar dinamicamente os intervalos de stop loss com base na volatilidade e noutras métricas.
Adicionar tendências de prazo mais longo e sinais das instituições para evitar entradas contrárias à tendência.
Considerar o dimensionamento das posições com base na volatilidade e no capital total.
Teste diferentes períodos de ancoragem do VWAP. Os períodos do VWAP determinam o período global de detenção da estratégia.

Resumo

A estratégia de ruptura de oscilação dupla VWAP identifica oscilação com ADX e fornece filtros de entrada adicionais com as bandas VWAP. A lógica é simples de implementar.
