VN Trader 2.6界面的数字如何改成千位分隔符加两位数字的格式？ 论坛：提问求助

2021年10月25日 08:19:26 UTC

VN Trader 2.6界面的数字如何改成千位分隔符加两位数字的格式？实在看起来不习惯。

例如：
静态权益:1,020,663.49，账户权益:1,033,572.23，账户权益:1,033,572.23
今日累计盈亏:12,908.74，浮盈:0.00，持仓盈亏:0.00，本交易日内平仓盈亏:14,440.00

我只知道在vnpy\trader\ui\mainwindow\MainWindow.init_dock() 里面改，水平有限，还没学会怎么改

vn.py 2.6数据管理模块，下载数据报错 论坛：数据相关

2021年10月19日 17:02:23 UTC

使用tushare数据源，代码如果写IF2112.CFX，则提示下载0条，
如果代码写IF2112，则抛出异常。
我用pro.fut_daily是可以正常下载的。
请问如何解决？

脚本运行方式，为什么导入app，IDE中为下划线红色仍然能正常运行 论坛：提问求助

2021年9月25日 06:00:00 UTC

Pycharm，脚本运行vnpy，run.py中，如下四句代码均显示红色下划线，ctrl+b（goto Declaration or Usage）也没找到对应的名字，main_engine.add_app能正常运行，在主程序中，也能正常使用，那这四个app是在哪导入的呢？
