Use the futures exchange object to call the exchange.GetMarkets() function in the backtesting system. Before calling any market function, GetMarkets only returns the market data of the current default trading pair. After calling the market function, it returns the market data of all requested varieties. You can refer to the following test example:

The exchange.GetMarkets() function returns a dictionary with a key named the name of the trade variety, and for spot fixes formatted as a trading pair, for example:

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

For futures contract exchanges, as there may be multiple contracts for a single variety, e.g. BTC_USDT trading pairs, there are perpetual contracts, quarterly contracts, and so on. The exchange.GetMarkets() function returns a dictionary with the key name of the pair combined with the contract code, for example:

{
    "BTC_USDT.swap" : {...},     // The key value is the Market structure
    "BTC_USDT.quarter" : {...}, 
    "LTC_USDT.swap" : {...},
    ...
}
  • The exchange.GetMarkets() function supports live tradings, backtesting system.
  • The exchange.GetMarkets() function returns market information only for the varieties that are traded on line on the exchange.
  • The exchange.GetMarkets() function does not support options contracts.
