Esta é uma estratégia de negociação quantitativa que utiliza os pontos de apoio como sinal de entrada. Calcula os pontos de apoio ascendentes e descendentes e inicia posições longas ou curtas assim que o preço os ultrapassa.
A estratégia baseia-se principalmente na teoria da inversão dos pontos de apoio. Primeiro, calcula os pontos de apoio da linha K da raiz N à esquerda e da linha K da raiz M à direita.
Quando o preço quebra o suporte de subida, a força de ranchang já não é suficiente para continuar a elevar o preço, então o shorting pode obter melhores ganhos. Quando o preço quebra o suporte de queda, a força aérea está esgotada, então fazer mais pode obter melhores ganhos.
Concretamente, a estratégia calcula os pontos de apoio de alta e baixa através das funções ta.pivothigh e ta.pivotlow. Em seguida, compara se o preço mais alto atual quebrou o ponto de apoio de alta e o preço mais baixo quebrou o ponto de apoio de baixa. Se for quebrado, inicie a estratégia de fazer mais curto correspondente.
Além disso, a estratégia também usa o stop loss para controlar o risco. A prática específica é, quando o preço quebra o ponto de apoio, imediatamente pedir, ao mesmo tempo em que o stop loss está localizado do outro lado do ponto de apoio, para evitar o máximo possível a expansão dos perdas causadas pelo single falho.
A estratégia baseada na inversão dos pontos de apoio tem as seguintes vantagens:
A estratégia também apresenta alguns riscos que devem ser lembrados:
Para reduzir o risco, considere:
A estratégia ainda tem espaço para ser melhorada:
Essas otimizações podem melhorar a taxa de vitória, o nível de lucro e a estabilidade da estratégia.
Resumindo, trata-se de uma estratégia de negociação quantitativa baseada na teoria do ponto de inflexão. Utiliza o ponto de inflexão do preço como sinal de negociação e controla o risco com o uso de um mecanismo de parada. A estratégia é fácil de implementar, de ampla aplicação e é uma estratégia de negociação quantitativa prática.
