抱歉官方文档没找到解答, 不是十分确定这三的理解是否正确:

以15分钟K線代碼为例

def on_15min_bar(self, bar: BarData):
self.cancel_all()

    am = self.am
    am.update_bar(bar)
    if not am.inited:
        return

    if self.pos == 0:
        self.intra_trade_high = bar.high_price
        self.intra_trade_low = bar.low_price

if not am.inited就return, return就不会再执行下面的代碼, 而am.inited=True是"该15分钟線成功合成的那一分钟", 只有在am.inited=True的时候才会执行下面的代碼.
那么如果在def on_15min_bar里调用bar.high_price, bar.close_price或bar.low_price, 是否每15分钟才计算入参一次? 这里面调用的是上一根15分钟bar的high, low, close?
因为这3个参数需要一根BAR走完结束才能确定, 但入参时是新bar的开始而非结束, 还是說他会一直计算, 取的是这根BAR里的high, low, close?

应该是QT问题，不要使用putty，使用vnc试试
很感謝大佬回复! 我又把run.py下的报错整段重复看了, 原來在报上述错誤之前还有別的缺包, 把里面提示的包全部用pip install之后就正常运行了, 包括vnpy_ctastragey, vnpy_ctp等等的包, 全部使用pip install解決了, 不过富途的包还不知道要怎么搞, futu路徑是vnpy.gateway.futu, 不是vnpy_futu, 所以还不知道怎么弄

VNPY的模块成功用pip install另外装好了, 运行run.py出現了新的问题, 也是没找到合适的方法:

在本地WINDOW系统没有问题, 打算上云测試, 买了阿里云香港UBUNTU20服务器, 折腾三天, 基本把论坛UBUNTU的贴子都爬了遍, 实在没招了來求助.

VNPY安装是显示成功的, 如果run.py中的模块用#注释掉, 可以打开VNPY, 但点击上方"功能"无反应, 如果不注释掉, 都会出現:
ModuleNotFoundError: No module named 'vnpy_ctastrategy'

vnpy_ctp, 回测模块, futu接口等等只要不注释掉一样会出現no module named.
在linux系统下搜索文件夹, 确实也搜不出任何VNPY_模块(我本地用WINDOW在sitepacket能看到模块文件夹)

于是判断是VNPY的安装出问题, miniconda应該是成功了的, 终端输入PYTHON能看到是3.7版本
在试图用bash install.sh安装时, 没有任何异常, 但在用python setup.py install安装, 会有如下红字(有几行是黃的):

已解決, 原來是win10本身的问题...

打开就这样了, 回測模块, 下載历史K線这两需要輸入日期的地方都不行, 没动过VNPY的代碼
