使用期货交易所对象，在回测系统中调用exchange.GetMarkets()函数。调用任何行情函数之前，GetMarkets只返回当前默认交易对的market数据，调用行情函数之后会返回所有请求过的品种的market数据。可以参考以下测试例子：
```json
{
"BTC_USDT" : {...}, // 键值为Market结构
"LTC_USDT" : {...},
...
}
对于期货合约交易所来说，因为一个品种可能有多个合约，例如：BTC_USDT交易对，有永续合约、季度合约等。exchange.GetMarkets()函数返回一个字典，键名为交易对与合约代码的组合，例如：
{
"BTC_USDT.swap" : {...}, // 键值为Market结构
"BTC_USDT.quarter" : {...},
"LTC_USDT.swap" : {...},
...
}
exchange.GetMarkets()函数支持实盘、回测系统。exchange.GetMarkets()函数仅返回交易所上线交易的品种市场信息。exchange.GetMarkets()不支持期权合约。不支持exchange.GetMarkets()函数的交易所：
| 函数名 | 不支持的现货交易所 | 不支持的期货交易所 |
|---|---|---|
| GetMarkets | Coincheck / Bithumb / BitFlyer | – |
