是vnpy\examples\vn_trader下的run.py吗？这个我跑起来的是vn_trader

设置一个断点调试一下就知道了，只有自己最了解自己写的代码

因为是把策略拷贝到专门的目录C:\Users\yuanhui\strategies下面，在vnpy\app\cta_strategy下面的策略文件中设置断点没用了。

请问有什么方法可以来设置调试

请教一下，CtaTemplate模块也是可以一个策略创建多个针对不同品种的实例吧，那也是实现了组合策略的结果吧。
是不是Portfolio Strategy可以在一份代码内部统一进行调度处理，灵活性更大了。而CtaTemplate的多个实例是分开跑的，没有统一的调度和处理

增加了一个参数，可以计算了。一个是布林线窗口，一个是宽度。
setting.add_parameter("bollWindow15min", 25, 30, 1)
setting.add_parameter("entryDev15min", 2, 3, 1)

最后的结果如下，这个结果对应选择的布林窗口长度和宽度是多少？是不是没有给出来

setting.add_parameter("bollWindow15min", 25, 30, 1)

用的是布林线窗口参数，开始25，结束30，步进1. 逻辑上应该没有问题啊

这个会是我策略的原因吗？还是bug.

这是啥原因

通过镜像站点安装成功了

于是自己安装plotly，但是总是不成功，是什么原因,如何解决呢？

这个get_account在回测的时候不能使用吧，在BacktestingEngine里面没有找到这个函数

我在template下面这个send_order函数上设置断点，在策略的on_order和on_trade上也设置了断点,，奇怪的是send_order程序没有跑到这里，但是on_order上不停的收到好几个止损的挂单，说明不是我的策略发出的挂止损单的信号。不知道是哪里发出来的？
def send_order(
self,
direction: Direction,
offset: Offset,
price: float,
volume: float,
stop: bool = False,
lock: bool = False
):
"""
Send a new order.
"""
if self.trading:
vt_orderids = self.cta_engine.send_order(
self, direction, offset, price, volume, stop, lock
)
return vt_orderids
else:
return []

是的，开仓已经平仓是写在策略里面的，在on_trade和on_bar函数里面。逻辑上应该是没问题的，调试了半天，没找到原因。

这种情况重复出现，下面的7.16号，11,17号都出现了。这应该和策略没关系吧

我查看了一下这里的K线，有一个隔日跳空。就是说价格跳过了之前的止损线，后面的那些重复的平仓单，是不是追单导致的啊？算不算是一个bug

问题比较奇怪，我是跑的日线策略，之前小时，15分钟策略都没有这个问题，不知道是不是这个原因。

我是在on_trade里面打印的。

调试能看到，开仓了14手，平仓了14手，但是后面还是不停收到平仓的消息，可能是什么问题？
下面是打印出来的trade消息，同一个时间的平仓消息不停的接收到。

自己记录了成交单调试了半天找到了问题了，self.pos记录的是对的。想了解下，CtaEngine里面没有记录sel.pos所对应的成交单的价格时间多空啥的吗？

我在策略里面记录下来了成交单，包括手数等。但是最后和self.pos对不上。哪里可以查询到self.pos对应的成交单，价格时间等
