通过脚本运行启动多个账户报错：zmq.error.ZMQError: Address in use
有大侠知道这个怎么解决吗？

同品种主力合约和次主力合约，在交割后合约名称就发生变化，请问这个怎么做3年以上时间回测呢，因为每个时间段主力合约次主力合约都不同，有大侠知道的能帮个忙解析一下吗？

在CtpGateway里面 onRtnDepthMarketData 函数里面，每个价格会用函数 adjust_price 做一个调整 ，也就是去掉一些异常大的数值。但是这个在融航的接口rohon_gateway里面并没有做，但是我模拟账户发现融航也是会出现一些异常大的数值，所以这个函数在rohon_gateway也是需要的。请有看到的版主下次可以考虑优化一下。但是这个异常值怎么会产生，有知道大虾可以解析一下吗？

def onRtnDepthMarketData(self, data: dict):
"""

symbol = data["InstrumentID"]
exchange = symbol_exchange_map.get(symbol, "")
if not exchange:

有没有人使用论坛里面提供的指数合成代码，发现一些异常的数据的？在合成tick数据的时候经常出现某个价格数值非常大的情况。像这 low_price=2.693714390689281e+305

由于需要对接MOM交易接口（不是融航），需要把对方给的CTP头文件和交易库转成python库即 vnctpmd 和 vnctptd，有没有大佬指导下怎么编译效果高一点？或者分享一下整个编译的流程。最好是windows环境下。

由于需要，接入杰宜斯平台所需要对应ctp版本为 6.3.15，有哪位大侠知道vn哪个版本是基于ctp 6.3.15版本的吗？貌似还没有看到有接入杰宜斯系统的。

融航账户，用vnstation可以登陆，用run.py就报4097错误，有大侠知道是什么原因吗？

有大虾对接过杰宜斯系统吗，有的话分享以下对接流程呗。

用Anaconda3.8最新版安装最新代码一直报错，改用Anaconda3.7版能正常安装。但是中途报了一个错误，是spyder 和 vnpy安装的pyqt5 5.14.1版本不兼容。在论坛里也有看到有人提问这个问题，没有给出解决办法。有大侠知道这个怎么解决吗？或是这个可以忽略，不影响使用？之前一直都是安装vn-station，这次采用手动安装方式，发现还是不少版本兼容问题。

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
spyder 3.3.2 requires pyqt5<5.10; python_version >= "3", but you have pyqt5 5.14.1 which is incompatible.

按照说明安装的最新版Anaconda，不过改版本是Python 3.9。发现 quikfix 和 TA_Lib 安装不了，即使下载到本地也是安装不了。基本上每次更新重新安装都是很多的库版本对不上或者有冲突。每次升级安装说明能否说明需要在哪个python版本下面去安装。

有大侠知道simnow模拟账户，持仓占用保证金与实盘交易占用保证金小得多的原因是什么吗？

请问有哪位大侠知道，vnpy模拟账户快期3平台，买进的合约没有平仓的情况下持仓均价每天都在增加吗？

有大侠知道simnow模拟账户现在申请不了吗？网站都打不开了。有没有其它支持VNPY模拟账户的平台呢？

vnpy界面效率目前能支持全市场合约以及指数合约全部实时tick数据正常显示吗？

portfolio_strategy组合策略模块回测不支持发送停损单（Stop Order），请问有大侠知道解决方案不？

有大侠用过XTP的吗，XTP可以做股票的全自动交易么？

请问有高手分享一下实时指数合约的合成方法或者代码不？就是根据实时合约的行情数据生成实时的指数。万分感谢！

比如实现利用指数合约做行情信号进行策略运算，交易实际映射到主力合约进行交易？

哪位大侠知道回测界面里面盈亏分布是什么意思？看了半天也不知道是啥意思，看代码是由每天盈亏算出来，但是看图没看明白。哪位大侠知道解答下！感谢！

请问策略多合约模块 PortfolioStrategy 要怎么样进行回测？运行回测的入口在哪里呢？
