可以了，看来是同时安装几个版本搞的。我是都安装在root下，conda几个环境，但是应该都装在.vntrader下冲突了。
如果创建几个不同的用户，再安装的话是不是可以避免这种情况？
你是说vnc服务器启动的时候吗，这个没有
我装了几个版本，是用conda创建不同的虚拟的环境安装的，按理说不影响啊。是不是数据库是共同的，
我这个是ubuntu系统，数据库放在哪个位置了

上面链接里面，这个回答可以
sudo apt-get install aptitude
sudo aptitude install <package-name>
其实是需要的，有时候要根据止损的大小来调整开仓数量的大小。也可以在总资金回撤的时候，减小仓位。
估计是。应该要做不少裁剪，只把最核心的算法移植过来。
这种需求应该比较普遍吧，以后应该有开发计划吧。毕竟策略执行的时候不能手工去干预实行算法交易。
群主的意思是说，可以自己把算法交易自己移植到策略里面是吗？
我看功能介绍算法交易是对交易的标的直接指定操作。
可以在策略中应用算法交易吗，事先配置好后在策略中下单的时候直接执行。
self.buy(self.boll_up, self.fixed_size, True)，这个是停止单，就是突破这个价格的时候买
没有对应的价格是什么意思，self.boll_up就是布林线上轨的位置啊，K线没有穿越布林线，那就是无法成交啊。
def boll(
self,
n: int,
dev: float,
array: bool = False
注意看这个 arry,缺省是false，就是返回的是一个值，就是数组最后的那个值
