托管者接受到的K线会持续累计在一起，需要有一定频率的去访问exchange.GetRecords接口，否则可能会影响数据的持续性。=======请问能举个例子说明k线累计在一起是什么意思吗？假定，数量设置为1条，k线周期设置为1分钟，我每10秒调用一次接口。那能否举个例子说明调用7次接口，每次返回的k线数据是什么样吗？

- 调用一次GetRecords，底层获取K线数据：[1,2,3,4,5]
- 调用一次GetRecords，底层获取K线数据：[2,3,4,5,6]
- 调用一次GetRecords，底层获取K线数据：[3,4,5,6,7]
K线累积指的就是，最终GetRecords函数返回给你的是：[1,2,3,4,5,6,7]
