+### 历史数据
 
-把下载的数据解压到正式环境的data_path（所有db文件放到该目录下，没有层级结构）
+ZVT支持数据增量更新，用户之间可以共享历史数据，这样可以节省很多时间。
 
-数据的更新是增量的，下载历史数据只是为了节省时间，全部自己更新也是可以的。
+#### 数据源
+> 新UI实时行情的计算基于QMT数据源，需要开通的同学可联系作者。
 
-#### 注册聚宽(可选)
 项目数据支持多provider，在数据schema一致性的基础上，可根据需要进行选择和扩展，目前支持新浪，东财，交易所等免费数据。
 
 #### 数据的设计上是让provider来适配schema,而不是反过来，这样即使某provider不可用了，换一个即可，不会影响整个系统的使用。
 
 但免费数据的缺点是显而易见的:不稳定，爬取清洗数据耗时耗力，维护代价巨大，且随时可能不可用。  
 个人建议：如果只是学习研究，可以使用免费数据；如果是真正有意投身量化，还是选一家可靠的数据提供商。

 > 项目中大部分的免费数据目前都是比较稳定的，且做过严格测试，特别是东财的数据，可放心使用
