使用浏览器端生成的回测参数：
start: '2021-04-01 00:00:00', end: '2021-04-02 00:00:00', period: '15m', basePeriod: '15m', exchanges: [{ "eid": "Futures_Binance", "currency": "BTC_USDT", "feeder": "http://xxx.253:9090", "quotePrecision": 6, "basePrecision": 0, "fee": [0.0244, 0.0244] }]

执行报错如下：
symbol not found BTC_USDT_Futures_Binance
