更新1.7.0后回测总是报错。提示“不在可交易时间段内”，然后整个程序异常退出！
有很多品种报错，如：jd2005，原 klines = api.get_kline_serial(SYMBOL, 60 * 30 )报错，
改为：klines = api.get_kline_serial(SYMBOL, 60 * 29 )jd2005能过去，不报错。
cu2005 klines = api.get_kline_serial(SYMBOL, 60 * 29 ) 报错，错误信息如下：

你有订阅其他合约吗
很奇怪的问题，反复调试发现报错与否可能随机出现。
下面代码限定条件, 运行后一定报错，你们看看什么原因，谢谢！

quote = api.get_quote(SYMBOL)
klines = api.get_kline_serial(SYMBOL, 60 * 29) #取消此订阅就不会报错了

好的，这个问题我们已经知道了，会尽快修好的
这个问题预计什么版本能解决？谢谢
回测的开始时间是填的什么呢?
