事件驱动型回测执行期货指数合约时报错

报错信息：

重现步骤：
JAQS/test/test_backtest_eventdriven.py中把test_backtest()函数中的合约设置为指数合约rb.SHF（在instrument.csv中得知），具体代码如下：
props = {"symbol": "rb.SHF",
"start_date": 20170710,
"end_date": 20170730,
"bar_type": "1M", # '1d'
"init_balance": 2e4}
然后执行该测试用例，在策略部分运行正常，然后在do_analyze()函数运行时出现上述异常。
