Use o objeto de troca de futuros para chamar oexchange.GetMarkets()Antes de chamar qualquer função de mercado, o GetMarkets retorna apenas os dados de mercado do par de negociação padrão atual. Depois de chamar a função de mercado, retorna os dados de mercado de todas as variedades solicitadas. Você pode se referir ao seguinte exemplo de teste:

Oexchange.GetMarkets()função retorna um dicionário com uma chave denominada o nome da variedade comercial e para as correções spot formatadas como um par comercial, por exemplo:

{
    "BTC_USDT" : {...},  // The key value is the Market structure
    "LTC_USDT" : {...},  
    ...
}

Para as trocas de contratos futuros, uma vez que podem existir vários contratos para uma única variedade, por exemplo:BTC_USDTOs contratos perpétuos, os contratos trimestrais e assim por diante.exchange.GetMarkets()A função retorna um dicionário com o nome da chave do par combinado com o código do contrato, por exemplo:

{
    "BTC_USDT.swap" : {...},     // The key value is the Market structure
    "BTC_USDT.quarter" : {...}, 
    "LTC_USDT.swap" : {...},
    ...
}
