测试了wind和tinysoft的datafeed配置，都是连通可获取数据的。

（可以获得BarData数据，TickData数据获取报错，图为配置tinysoft）
（配置wind的datafeed情况下，也是只能获得BarData，TickData获取为空）
直接在notebook中使用wind/tinysoft对应的api，都可以正常获取tick数据。

但在datamanager和ctabacktester中无法下载数据。

已尝试在excel中将csv刷成文本格式，但是csv格式文件本身不带格式，此方法亦无果。

sqlite数据库在2.5版本后添加了turnover， 删除用户名目录下.vntrader中的database.db文件。重新启动vnpy即可，如果sqlite中有重要数据，请先备份数据。
