镍提示平昨仓位不足 论坛： CTP

2019年11月25日 05:27:29 UTC

V1.92版vnpy，镍平仓的时候提示：错误代码：51，错误信息：CTP:平昨仓位不足
仓位是周五夜盘开的，周一早上平仓，vnpy发出的平仓单应该是平今不是平昨吧？不知为何会提示平昨仓位不足。

导入策略报错和CTP接口不存在 论坛： CTP

想请问两个问题：

看穿式监管提示 “接口不存在：CTP” 是我的地址输入错了还是券商那边把测试用的接口关了？
这个ImportError研究了半天都没解决，在单独的python脚本里面import numpy是没有问题的。

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the multiarray numpy extension module failed. Most
likely you are trying to import a failed build of numpy.
Here is how to proceed:

If you're working with a numpy git repository, try git clean -xdf
(removes all files not under version control) and rebuild numpy.
If you are simply trying to use the numpy version that you have installed:
your installation is broken - please reinstall numpy.
If you have already reinstalled and that did not fix the problem, then:
1. Check that you are using the Python you expect (you're using D:\Anaconda\python.exe),
  and that you have no directories in your PATH or PYTHONPATH that can
  interfere with the Python and numpy versions you're trying to use.
2. If (1) looks fine, you can open a new issue at
  https://github.com/numpy/numpy/issues. Please include details on:
  - how you installed Python
  - how you installed numpy
  - your operating system
  - whether or not you have multiple versions of Python installed
  - if you built from source, your compiler versions and ideally a build log
  Note: this error has many possible causes, so please don't comment on
  an existing issue about this - open a new one instead.

1.9版本ArrayManager初始化size问题 论坛： CTA策略

2019年4月14日 09:51:45 UTC

1.9版本，BarGenerator使用5分钟周期，self.bg = BarGenerator(self.onBar, 5, self.onXminBar)
ArrayManager初始化 self.am = ArrayManager(100)
在初始化size这里输入100的话，请问vnpy会从数据库里面提取100根1分钟的bar还是500根1分钟的bar来初始化指标？

1.9版本直接运行CTA Trading，最多可以同时运行多少CTA策略实例 论坛： CTA策略

2019年4月14日 09:38:43 UTC

请问1.9版本通过命令行直接运行CTA Trading，

一个vnpy线程在计算指标和下单速度不受影响的话，最多可以同时运行多少CTA策略实例？
比如一个vnpy线程最多运行100个策略实例可以保证计算和下单不受影响，那同时开两个vnpy线程每个运行100个CTA策略实例，跟开一个vnpy线程运行200个实例相比，速度上会有多大优势呢？
谢谢！

V1.92版DataEngine中getContract函数 论坛： CTA策略

2019年4月1日 17:24:49 UTC

请问调用DataEngine中的getContract函数时，是从本地硬盘读入合约信息还是从交易所获取？如果从本地硬盘读入的话，数据是存在哪里的，什么时间获取的？
我需要每个tick都调用getContract函数来获取合约信息，比如priceTick，如果在本地某文件中保存合约priceTick信息，程序开启时把合约信息读入内存，每个tick从内存中读取合约信息，会不会比执行getContract函数更快？多谢！
