Resumo

A Estratégia de Negociação DCA gradual ponderada quantificada é uma estratégia quantitativa de negociação que combina indicadores de média móvel para acionamento de sinais e mecanismos de média gradual de custo em dólares.

Princípios

A estratégia consiste em três componentes principais:

Julgamento do sinal de entrada

Ele usa cruzamento de média móvel rápida e lenta como sinal de entrada. Os usuários podem escolher entre SMA, EMA ou HMA para as médias móveis rápidas e lentas. Quando o MA rápido cruza acima do MA lento, um sinal de compra é gerado. Quando o MA rápido cruza abaixo do MA lento, um sinal de venda é gerado.
DCA gradualmente ponderada

Após um sinal de compra, a estratégia abrirá imediatamente uma posição de base. À medida que o preço continua a cair, a estratégia aumentará gradualmente o tamanho de posições de segurança adicionais de forma ponderada. O preço de cada nova posição de segurança será reduzido em uma porcentagem fixa em relação à anterior. Além disso, os fundos alocados para cada nova posição de segurança serão amplificados por um fator.

Este aumento gradual da dimensão das posições permite uma forma de média de custos, obtendo um melhor custo médio, mantendo os riscos sob controlo.
Obter lucro e parar perdas

Quando o preço sobe acima da linha de take profit, a estratégia fechará as posições para obter lucro.

A linha de lucro é fixada ao preço médio da posição de base * (1 + percentagem fixa).

A linha de stop loss flutua com base no último preço da posição de segurança, percentagem fixa abaixo dele.

Vantagens

A combinação de tendência e média de custos torna mais estável

Usar tendências evita problemas sem sentido, e a média de custos proporciona melhores custos de entrada.
O dimensionamento gradual da posição controla o risco

A amplificação fixa dos tamanhos das posições de segurança, com limiar de reentrada, mantém o risco sob controlo.
Monitorização em tempo real dos fundos utilizados

O indicador de utilização do saldo incorporado previne a alavancagem excessiva e as liquidações forçadas.
TP/SL separados para cada posição

As saídas independentes permitem assegurar lucros e reduzir perdas.

Riscos e melhorias

A queda de preços pode desencadear várias ordens de segurança.

Na volatilidade extrema, várias ordens de segurança desnecessárias podem ser adicionadas, aumentando a perda.
Os parâmetros da média móvel precisam de otimização

Diferentes instrumentos precisam de períodos de média móvel diferentes.
Os níveis de TP/SL necessitam de otimização dos backtests

Os rácios TP/SL determinam o perfil risco/recompensa.
Adicionar saída forçada baseada no tempo máximo de retirada ou de retenção

Pode testar incorporando saídas forçadas com base no tempo de retirada ou de retenção para limitar ainda mais os riscos.

Resumo

A estratégia de negociação DCA gradual ponderada quantificada combina as vantagens da negociação de tendências e da média de custos para produzir retornos estáveis em tendências fortes. Com parâmetros otimizados, dimensionamento de posição e limiares de reentrada, pode alcançar negociações estáveis com risco controlado. Aplicável a fundos de hedge, CTAs e estratégias neutras de mercado.
