使用TuShare数据服务，实盘初始化策略，默认initDays=10，例如11点钟重启后初始化，没有tick的数据，只能从TuShare拿到1分钟k线数据，能完成能初始化吗？

如下图所示，vnpy3.6中主界面成交栏无策略来源，在委托和活动界面均有策略来源，官方是否可以考虑增加一下吗？

如图所示，在vnpy3.6版本中，行情涨跌幅不变动，买一卖一的价格可以随行情变动，但是涨跌幅一直停留在-100.06%,尝试删除.vntrader也无解

Mac Mini M2安装vnpy3.6报错代码如下所示：

使用的是全新的Mac Mini M2，参照如下官方教程一步一步操作的https://mp.weixin.qq.com/s/OB4TpVnipueFO-pbXyz_Rg

另外咨询一下，mac os系统官方集成版本的VeighNa Studio软件大概什么时候推出？

在vnpy3.6中使用taos数据库,通过csv导入数据时报错如下，具体怎么回事儿呢？

C:\Users\Administrator\Desktop\vnpy-3.6.0>python  run.py
找不到数据服务驱动vnpy_，使用默认的RQData数据服务

咨询一下，vnpy3.6目前支持的数据库性能排行榜是否如下图所示顺序呢？涛思taos数据库是否vnpy3.6已支持？

vnpy3.6回测报错，如下图所示

VNPY3.6在vnpy_ctastrategy/vnpy_ctabacktester的CTA策略模块执行参数优化时添加了最大进程数量限制参数max_workers,请教一下，这个参数具体怎么设置？ 然后设置最大可以是多少？最大线程数能超过63吗？

咨询一下自己发的帖子可以自己删除吗？有些没必要的想删除了

通过这样的方式可以拿到所有委托数据：

orders = main_engine.get_all_orders()

想在no_ui中获取到所有委托数据orders，但是具体不知道引入那些包？ 具体如何才能拿到委托数据？方便具体指导一下吗？万分感激万分感激万分感激万分感激

运行no_ui时，使用sleep阻塞主线程，更重要是因为如果其中有一个CTA初始化失败报错，那么主线程就不会进入下一步，卡在while循环了，或者如果CTA策略需要从数据源实时下载数据延迟，或者CTA策略有上百个时候，还没有等全部初始话完成，就启动了也会报错，望指导。

如上图所示，vnpy2.6版本重新安装后无委托号、来源、代码显示，有什么办法解决吗？

如图所示，30分钟周期，实盘中因网络断开原因导致CTA策略委托状态一直处于“提交中”，有办法网络恢复后，重新发送之前一直处于状态“提交中”的委托订单吗？而不必等待下一个30分钟k线推送过来后重新发送新的委托订单

老师好，咨询一下，如何在关闭软件时，自动保存vnpy主界面mainwindow中委托订单的数据到csv，复盘参照log感觉不太直观，望指导一下，水平不高，感谢。

如下图所示，vnpy3.5和vnpy2.6重启后，在on_bar下面的self.cancel_all()无法撤销vnpy在重启之前发往盈透的停止单，但是在主界面委托窗口，还是可以通过双击撤销之前发到盈透的停止单，这是什么原因导致的呢？有什么办法解决呢？

帖子https://www.vnpy.com/forum/topic/7891-ctace-lue-ke-cheng-zhong-yu-2-6-0ban-ben-bu-yi-zhi-de-di-fang?page=1#pid28997

课时8-K线的自定义合成
问题：
2.6.0版本对部分源代码进行了重构，其中就包括了该课程中的BarGenerator，所以课程具体的源代码与课程中展示的不完全一致。

解决方案：
2.6.0版本对BarGenerator进行了重构，对于update_tick函数做了一些改进，同时对于update_bar函数更新分钟数据和小时数据的逻辑分离成了两个独立的函数，分别为update_bar_minute_window函数和update_bar_hour_window函数，虽然与课程中展示的不完全一致，但是功能都是一致的。因此如果大家想要按照课程中所展示的代码自定义一个可以生成类似7分钟这种分钟数据，应该对update_bar_minute_window函数进行复制后再做修改。可以尝试修改如下：

def update_bar_minute_window(self, bar: BarData) -> None:
""""""

    # If not inited, create window bar object
    if not self.window_bar:
        dt = bar.datetime.replace(second=0, microsecond=0)
        self.window_bar = BarData(
            symbol=bar.symbol,
            exchange=bar.exchange,
            datetime=dt,
            gateway_name=bar.gateway_name,
            open_price=bar.open_price,
            high_price=bar.high_price,
            low_price=bar.low_price
        )
    # Otherwise, update high/low price into window bar
    else:
        self.window_bar.high_price = max(
            self.window_bar.high_price,
            bar.high_price
        )
        self.window_bar.low_price = min(
            self.window_bar.low_price,
            bar.low_price
        )

    # Update close price/volume/turnover into window bar
    self.window_bar.close_price = bar.close_price
    self.window_bar.volume += bar.volume
    self.window_bar.turnover += bar.turnover
    self.window_bar.open_interest = bar.open_interest

    # Check if window bar completed
    if self.window_bar.datetime.minute != bar.datetime.minute:
        self.interval_count += 1
        if not (bar.datetime.minute + 1) % self.window:
            self.on_window_bar(self.window_bar)
            self.window_bar = None
            self.interval_count = 0

使用vnpy3.5版本，发现《CTA策略》课程中与2.6.0版本的代码自定义k线合成45分钟k线有误，如上图所示，自定义45分钟，第一根为45分钟的k线，后面的就变成了每个小时的45分钟，第一根为45分钟的k线，第二根不是应该30分钟时出现吗？

咨询一下vnpy3.5版本的海龟策略怎么优化那么慢呢？其他策略一般3个小时左右就优化完了，这个自带的海龟策略很少几个参数优化了一天一夜？

vnpy发出stop停止单到盈透服务端后，重启了vnpy，如何才能获取到之前发出的停止单是否已经成交？如果未成交如何取消之前发出的停止单？

self.cancel_all()能取消掉已经发到盈透服务端的停止单吗？如果不能取消，怎么操作才可以取消掉已经发往盈透服务端的停止单呢？

之前vnpy2.1的时候一直正常，策略初始化后不会有图片的报错，现在升级vnpy3.5版本后，每次连接成功，策略初始化完成后，就会返回如下图的报错，望修复一下此BUG
