上海期货交易所CTP行情和交易接入
发布时间：2018-09-25
技术：C++11,动态库的制作
概述
CTP的接入Demo
详细
本文档不介绍CTP的具体流程，具体流程请参考上海期货交易所文档(下载).
一、概述
1.CTP是上期技术，提供的国内期货行情和交易的接口，自推出以来，各大券商均架设了CTP技术的接入，引入策略算法便可以初步形成一个自动交易的系统，这也就吸引了很多对自动交易，策略交易感兴趣的各路高人来使用。
2.CTP难点在于，一个库提供了行情和交易两套接口，各自均有一套业务流程，而且两者在业务上还存在部分业务关联，也就是说还要处理两套之间的业务同步问题，没有一些C++基础的人很难开发好用的CTP库。
3.本Demo目标是，在Windows环境下做两个程序：
一个封装CTP行情和交易接口成一个库，尽可能在高内聚低耦合的情况下，保持代码清晰，通俗尽可能让；
一个执行程序很容易的去调用这个库，这里没有使用MFC或QT，直接采用控制台程序，很清晰的展示使用库。
二、准备环境
1.开发工具:visual studio 2015或以上版本（下载）
本Demo采用Visual studio 2015 专业版 update 3
Windows7 64位
2.下载上期CTP库（下载）
综合交易平台API下载，下载列表中的windows下64位库（最新(2015-05-15)），解压如下:
3.申请模拟账号(申请)
主页右上角，注册账号，例子中方便开箱即用，会使用我自己申请好的，请自行换成自己的帐号。
三、程序介绍
1.先看下Demo的运行效果。
2.程序目录结构
①Show all files模式下，VS工程目录结构如下图:
共两个项目,CTPSample和CTPServer,CTPSample为封装交易所CTP的动态库，CTPServer为使用库的UI程序。
②代码目录结构
bin64
-----CTP CTP产生的共享文件
-----Log 日志文件
config.cfg 配置文件
build
CTPServer.sln 存放工程文件
Src
------CTPSample DLL代码
------CTPServer UI代码
------Framwork 框架代码，避免复杂，不做公开（这里主要提供日志，数据定义，可自己替换）
说明：confg.cfg主要保存了CTP的地址(其他均为非本Demo演示的主要功能)：

CTPFront.quote1 = tcp://180.168.146.187:10031
CTPFront.trade2 = tcp://180.168.146.187:10001

CTPFront.trade3 = tcp://218.202.237.33:10002
CTPFront.quote3 = tcp://ctp1-md11.citicsf.com:41213

//用于给上层订阅
typedef vector<CPacketReceiver*> VPKTRECEIVER;
VPKTRECEIVER m_vPketReceiver;
};
主要功能点:
①模块管理:
CTP的行情模块分两块，一个是同步查询API（CThostFtdcMdApi），一个是异步回报API（CThostFtdcMdSpi），这里定义了一个包装类，来管理这两类API，即
MyRecv来封装CThostFtdcMdSpi，CThostFtdcMdApi直接使用。
②给UI回报接口
本模块提供给上层的接口，定义了一个虚基类：
class CPacketReceiver
{
public:
virtual void Receive(CBroadcastPacket &pkt) = 0;
};
这里运用到actor模式，接受UI订阅：
typedef vector<CPacketReceiver*> VPKTRECEIVER;
VPKTRECEIVER m_vPketReceiver;
③数据保存
数据收集，定义几个map
map<string /*InstrumentID*/, CThostFtdcInstrumentField> m_mapInstrument;//合约ID，合约信息 map<string /*InstrumentID*/,CThostFtdcDepthMarketDataField /*Quotation*/> m_mapInstrumentQuote;//保存 合约ID-最新行情 对,合约ID唯一。 vector<string /*InstrumentID*/> m_vecInstrumentId;//合约ID

};
①模块管理:
与CTP提供的行情库类似，这里定义了API和封装的回报API，如下：
CThostFtdcTraderApi* m_reqApi; MyRecv *m_RecvSpi;
②与UI通信
由于交易API用的比较频繁，而回报主要在初始化阶段和数据更新，没有定义回报接口，定义的是全局单例模式，直接共上层使用。
③数据管理
// 保存合约 map<string, CThostFtdcInstrumentField> m_mapInstrument;//合约ID，合约信息 map<wstring, map<wstring, map<wstring, CThostFtdcInstrumentField>>> m_mapInstrument2;//交易所，板块，合约信息
3.程序注意点
①UI初始化:
调用TradeManager::InitCTP启动CTP模块，主模块会订阅注册：
MyCTPQuote::Instance()->Subscribe(this);
②交易模块与行情模块通信
当交易模块登陆成功后（通能说原子操作，来判断多条件满足），来调用行情的完成函数，已便行情模块来进行行情合约订阅
int Qry = atomic_exchange(&MyCTPTrade::Instance()->m_bQryIns, false); int QryOK = atomic_exchange(&MyCTPTrade::Instance()->m_bQryInsOK, true); if(!Qry && QryOK) FinishQryInstrument();
③行情回报
收到行情回报，会调用下函数：
void MyCTPQuote::OnRtnDepthMarketData(CThostFtdcDepthMarketDataField *pDepthMarketData)
并组织结构，向订阅派发:
CBroadcastPacket pack;
///深度行情通知
///每秒两次行情
void MyCTPQuote::OnRtnDepthMarketData(CThostFtdcDepthMarketDataField *pDepthMarketData)
{
if (pDepthMarketData->OpenPrice >= LDBL_MAX)
pDepthMarketData->OpenPrice = 0;
if (pDepthMarketData->HighestPrice >= LDBL_MAX)
pDepthMarketData->HighestPrice = 0;
if (pDepthMarketData->LowestPrice >= LDBL_MAX)
pDepthMarketData->LowestPrice = 0;
if (pDepthMarketData->ClosePrice >= LDBL_MAX)
pDepthMarketData->ClosePrice = 0;
if (pDepthMarketData->PreClosePrice >= LDBL_MAX)
pDepthMarketData->PreClosePrice = 0;
string str = "Quote SDK 接收行情信息:InstrumentID:";
str += pDepthMarketData->InstrumentID ;
str += " TradingDay:"; str += pDepthMarketData->TradingDay;
str += " LastPrice:"; str += to_string(pDepthMarketData->LastPrice);
str += " Volume:"; str += to_string(pDepthMarketData->Volume);
str += " OpenPrice:"; str += to_string(pDepthMarketData->OpenPrice);
str += " HighestPrice:"; str += to_string(pDepthMarketData->HighestPrice);
str += " LowestPrice:"; str += to_string(pDepthMarketData->LowestPrice);
str += " ClosePrice:"; str += to_string(pDepthMarketData->ClosePrice);
str += " PreClosePrice:"; str += to_string(pDepthMarketData->PreClosePrice);
str += " UpdateTime:"; str += pDepthMarketData->UpdateTime;
CRLog(E_APPINFO, str.c_str());
//本地保存
//转发到界面
//CThostFtdcDepthMarketDataField DepthMarketData;
//memcpy_s(&DepthMarketData, sizeof(DepthMarketData) ,pDepthMarketData , sizeof(CThostFtdcDepthMarketDataField));
//m_mapInstrumentQuote[pDepthMarketData->InstrumentID] = DepthMarketData;
m_mapInstrumentQuote[pDepthMarketData->InstrumentID] = *pDepthMarketData;
pack.SetParameter("InstrumentId", pDepthMarketData->InstrumentID);
pack.SetParameter("TradingDay", pDepthMarketData->TradingDay);
pack.SetParameter("OpenPrice", pDepthMarketData->OpenPrice);
pack.SetParameter("HighestPrice", pDepthMarketData->HighestPrice);
pack.SetParameter("LowestPrice", pDepthMarketData->LowestPrice);
pack.SetParameter("ClosePrice", pDepthMarketData->ClosePrice);
pack.SetParameter("PreClosePrice", pDepthMarketData->PreClosePrice);
pack.SetParameter("UpperLimitPrice", pDepthMarketData->UpperLimitPrice);
pack.SetParameter("LowerLimitPrice", pDepthMarketData->LowerLimitPrice);
pack.SetParameter("AskPrice1", pDepthMarketData->AskPrice1);
pack.SetParameter("AskVolume1", pDepthMarketData->AskVolume1);

pack.SetParameter("BidVolume1", pDepthMarketData->BidVolume1);
pack.SetParameter("LastPrice", pDepthMarketData->LastPrice);
pack.SetParameter("Volume", pDepthMarketData->Volume);
//给上层转发
// 广播报文
for (VPKTRECEIVER::iterator it = m_vPketReceiver.begin(); it < m_vPketReceiver.end(); it++)
{
(*it)->Receive(pack);
}
}
④界面处理回报数据
收到数据可以按照自己的逻辑处理，本Demo进行了写共享队列。
QUOTATION quo = { 0 };
void TradeManager::Receive(CBroadcastPacket &pkt)
{
unsigned int nLen = 0;
const char* pcBuf = pkt.Encode(nLen);
//分发给相应队列处理
quo.Decode(pcBuf, nLen);
int uiCount = 0;
string sXQueName, sTmp;
for (vector< CXQueueIo<QUOTATION>* >::iterator it = m_vecQueueIo.begin(); it != m_vecQueueIo.end(); ++it)
{
uiCount++;
if (0 != *it)
{
(*it)->Enque(quo);
sXQueName = "XQUE" + strutils::ToString<unsigned int>(uiCount);
sXQueName += ".XQUE_NAME";
if (0 == m_pConfig->GetProperty(sXQueName, sTmp))
sXQueName = sTmp;
CRLog(E_APPINFO, "共享队列XQueue[%s]写完成", sXQueName.c_str());
}
}//end for
}
4.注意
内嵌Framwork所生成的动态库为本Demo提供日志和共享内存队列以及行情数据定义，可以自行定义替换，不存在bug，不影响演示，代码由于版权问题，暂不能公开，若有需要，请联系作者。
