Esta estratégia é usada para obter e monitorar as taxas de financiamento de várias plataformas de futuros, como OKCoin, Binance, Bitget, etc. Ele pesquisa os mercados de contratos perpétuos de várias bolsas através de tópicos paralelos e obtém dados de taxa de financiamento, ao mesmo tempo em que usa um mecanismo de atraso para otimizar a frequência de solicitação.
Este artigo faz algumas alterações na estratégia para suportar a exibição e a taxa de financiamento alarme push funções.

Pode ajustar a lista de plataformas, a lista de símbolos e o intervalo de sondagem conforme necessário para satisfazer as suas necessidades comerciais específicas.
