rqalpha-mod-vnpy's Introduction

rqalpha-mod-vnpy

RQAlpha 对接 vnpy 的扩展 Mod。通过启用该 Mod 来实现期货策略的实盘交易。目前本模块仍处在正式发布前的测试阶段，您可以下载参与测试并开 Issue 提交 bug，也欢迎您提交代码，参与开发。

本开源模块未进行详尽完备的测试，作者不保证您通过本模块获取到数据的完整以及准确性、不保证您的策略逻辑正确触发对应的实盘操作，您通过使用本模块实盘操作产生的损益与作者无关。

当前版本的 rqalpha-mod-vnpy 仅支持 VN.PY 的最新版本，请您及时更新 VN.PY 的代码

环境要求

由于 VN.PY 项目仅支持 Linux 和 Windows 系统，python2.7 环境，目前本模块也仅支持在 Linux 或 Windows 系统下 python2.7 环境。
作者仅在 ubuntu 16.04 LTS 系统进行了测试。关于 Windows 及其他 Linux 发行版下的兼容性，作者会在精力允许的情况进行测试，也欢迎您将兼容性情况反馈给我。

编译和安装

本模块依赖 RQAlpha 和 VN.PY 两个项目，所以需要完成两个项目的安装。

安装 RQAlpha

rqalpha-mod-vnpy 依赖 2.0.X 版本的 RQAlpha，您可以执行如下命令来安装 RQAlpha

pip install -U rqalpha

安装 VN.PY

VN.PY 项目未提供 pip 安装包，所以您只能通过下载源代码自行编译的方式进行安装。详细的环境配置和安装说明您可以查看 VN.PY官方教程。

安装 mod

在您完成 RQAlpha 的安装之后，您可以执行以下命令来安装 mod：

rqalpha mod install vnpy

之后您可以执行以下命令来启动 mod:

rqalpha mod enable vnpy

如果您需要关闭或者卸载 mod 您可以执行以下两条命令:

rqalpha mod disable vnpy

rqalpha mod uninstall vnpy

配置项

您需要在配置项中填入 vnpy 相关文件夹的路径及您的 CTP 账号密码等信息，您可以在 simnow 官网申请实盘模拟账号。
配置项的使用与 RQAlpha 其他 mod 无异

"vnpy": {
    # 您需要接入的接口，目前仅支持 CTP
    "gateway_type": "CTP",
    # VN.PY 项目目录下有一个 vn.trader 文件夹，您需要把该文件夹的路径填到此处
    "vn_trader_path": None,
    # 您使用 simnow 模拟交易时可以选择使用24小时服务器，该服务器允许您在收盘时间测试相关 API，如果您需要全天候测试，您需要开启此项。
    "all_day": True,
    # VN.PY 创建临时文件的目录
    "temp_path": "./vnpy_temp",
    # 以下是您的 CTP 账户信息，由于您需要将密码明文写在配置文件中，您需要注意保护个人隐私。
    "CTP": {
        "userID": "",
        "password": "",
        "brokerID": "9999",
      	"tdAddress": "tcp://180.168.146.187:10030",
      	"mdAddress": "tcp://180.168.146.187:10031",
    },
}

开箱即用虚拟机

为了让用户能够在最短时间内体验 rqapha-mod-vnpy，免去繁琐的环境配置和接口编译，作者提供了开箱即用的虚拟机镜像。

有关虚拟机镜像的导入以及 rqalpha 的调试和运行，您可以参考 rqalpha 文档。

点此下载

体验 rqalpha-mod-vnpy

双击打开桌面上的 rqalpha_vnpy_test.py 文件，在配置文件对应位置填入您的 simnow userID 和密码
打开终端，依次输入如下命令:

cd /home/rqalpha_user/桌面

source activate py2

python rqalpha_vnpy_test.py

FAQ

为什么策略在初始化期间停滞了几十秒甚至数分钟？

程序在启动前，需要从 CTP 获取 Instrument 和 Commission 等数据，由于CTP控流等原因，像 CTP 发送大量请求会占用很长时间。您可以将 log_level 设置成 verbose 来查看详细的回调函数执行情况。未来可能会考虑开放设置是否全量更新 commission 信息以换取更快的启动速度。*
为什么我在RQAlpha中查询到的账户、持仓信息与我通过快期、vn.trader 等终端查询到的不一致？

本 mod 会尽力将您的账户信息恢复至 RQAlpha 中，但由于计算逻辑的不同，可能会导致各个终端显示的数字有差异，另外您通过其他终端下单交易也有可能导致数据同步的不及时。不过这也有可能是程序bug，如果您发现不一致情况严重，欢迎通过Issue的方式向作者提出。*
VN.PY 的环境配置和安装比较复杂，我搞不定／懒得搞怎么办？

作者会尽力研究，争取将VN.PY的安装包含进 mod 中，通过 pip 的形式一键安装，在这之前，作者会提供一个开箱即用虚拟机镜像，供您直接下载使用。*
为什么会报 NotImplementedError？

请尝试将配置文件中的 frequency 设置为 tick。
我如何在 python3.x 下使用该 mod？

您可以尝试使用 rqalpha-mod-ctp，该 mod 实现了 python3.x 的支持。待 rqalpha-mod-ctp 逐步完善后，rqalpha-mod-vnpy 将不再维护。

数据和交易解耦

分离数据和交易部分，在使用 rqalpha-mod-vnpy 的时候数据和事件不一定要通过 vnpy 获得，应允许替换数据源和事件源。

运行vnpy mod报错，详细信息如下：

log太长，发个文件：
log20170420.txt

适配 vnpy 新版本

vnpy 这两天提交了不少新代码，改动比较大，rqalpa-mod-vnpy 也需要做相应的适配。

脱离 vtGateway

由于 vtGateway 的封装程度比较高，一些函数的封装不适用于rqalpha。故决定尝试脱离 vtGateway，参照 vtGateway 的模式重写 gateway。

在vnpy mod里如何做vnpy的交易呢？

运行vnpy mod时报错

rqalpha version: 2.0.7
rqalpha_mod_vnpy version: 0.9.11
使用pycharm运行；

今天又没有这个错误了。

vnpy在onRtnDepthMarketData的问题

vnpy封装的 onRtnDepthMarketData函数会对volume=0的数据进行过滤。
导致在非交易时段调用subscribe函数没有当前最新快照数据返回，无法计算出portfolio.total_value（举例来说，有股指期货仓位的策略在夜盘时间打印portfolio信息，直接报错退出）。
需要进行改写，或者加入QryDepthMarketData函数。

如何通过代码运行 rqalpha-mod-vnpy？

启动恢复仓位时出现空仓key error

在每次启动vnpy的时候，系统都会自动查询当前仓位信息加载到RQA中。发现当出现空方向仓位的时候就直接报key error了。查看代码发现data_factory中cache_vnpy_position_before_init函数中的空仓字段写错。不应为sell_position，而应为sell_quantity

我运行vnpy mod报错，具体信息如下：

加入 RPC 模式

vnpy mod运行几分钟后，停止运行，弹出python.exe已停止工作的提示

用pycharm运行；

程序初始化时获取不到某些合约的last_price导致portfolio有关计算出错

目前逻辑是在订阅市场行情 cache住，需要用到时候从里面获取。
但是不同品种期货交易时间不同，比如夜盘，就无法获取到股指期货的市场行情。
此时应当用持仓查询返回的昨结算价作为last_price

初始化时获取重复获取open orders，仓位回复时候昨仓有误

对于仓位获取，注意上期所一个方向可能会返回两条仓位记录，一条昨仓，一条今仓。
由于YdPosition数据有误，所以使用Position获取当前总仓位，使用TodayPosition获取今仓，两者相减得到昨仓。

发送平仓单时针对上期所平今的处理

VNPY的Close只能平上期所昨仓。平今仓需要设置为CloseToday。所以buy_close 以及 sell_close 需要对上期所合约智能识别。举例来说，当前昨仓5，今仓3.当平仓数量为6的时候，按照先进先出的方式，先平昨仓5，后平今仓1，发送2个平仓单。此时函数应返回order list。与此同时，cancel_order API也应当支持对于order list的cancel操作。如果平仓数量为10的时候，则将昨仓5、今仓3分别发送平仓单。

这用的ctp接口是64位还是32位的？

如题。

如果64不行的话，能不能资辞一下64位的？
