CTP行情API

 一、期货行情数据

Tick数据一般指市场上的逐笔数据,例如一笔委托会产生一笔行情,一笔成交也会产生一笔行情。目前国内期货交易所还不支持推送逐笔数据,只推送切片(快照)数据。

切片数据是指将一定时间内的逐笔数据统计成一个快照发出,一般是1秒2笔。CTP行情转发的交易所行情,500ms一次快照。

二、CTP行情

1、CTP行情API简介

CThostFtdcMdApi行情API接口包含CThostFtdcMdApi和CThostFtdcMdSpi,通过CThostFtdcMdApiApi向CTP发送命令,通过CThostFtdcMdSpi接收CTP响应。

(1)创建CTP API实例

CThostFtdcMdApi *pMarketDataApi = CThostFtdcMdApi::CreateFtdcMdApi(dirName);

调用CreateFtdcMdApi()创建API实例,pMarketDataApi,通过API实例发起各种请求,如连接服务器、用户登录、订阅合约、退订合约等。

(2)创建CTP API回调实例

MarketDataSource *pDataSource = new MarketDataSource(pMarketDataApi, this);

开发者需要继承上期技术提供的CThostFtdcMdSpi类,重写类方法,以处理服务器发过来的各类数据。

(3)注册CTP API回调实例

pMarketDataApi->RegisterSpi(pDataSource);

(4)连接行情前置服务器

pMarketDataApi_->RegisterFront((char *)serverAddr_.c_str());

pMarketDataApi_->Init();

连接请求发出后,OnFrontConnected()会响应请求,通常在OnFrontConnected()函数内进行用户登录。

(5)用户登录

在OnFrontConnected()函数内进行用户登录操作。

CThostFtdcReqUserLoginField loginReq;
std::string BrokerID, InvestorID, Password;
memset(&loginReq, 0, sizeof(loginReq));
strcpy(loginReq.BrokerID, BrokerID.c_str());
strcpy(loginReq.UserID, InvestorID.c_str());
strcpy(loginReq.Password, Password.c_str());
static int requestID = 0;
int rt = pMarketDataApi->ReqUserLogin(&loginReq, requestID++);

登录请求后OnRspUserLogin()返回响应,如果登录成功,可以订阅合约。

(6)订阅期货合约

在OnRspUserLogin()函数内订阅期货合约。

const size_t count = contracts.size();
char *instruments[count];
pMarketDataApi_->SubscribeMarketData(instruments, (int)count);

(7)合约订阅响应

在OnRspSubMarketData函数内返回合约订阅结果,如果客户端订阅行情的请求是不合法的,返回服务器端给出的错误信息(pRspInfo);即使客户端发送的订阅请求是合法的,函数也会被回调,而返回的信息则是CTP:No Error。

(8)接收行情

void CTPMarketDataSource::OnRtnDepthMarketData(CThostFtdcDepthMarketDataField *
                                                pDepthMarketData);

合约订阅成功后,在交易时间段内,所订阅合约行情数据会源源不断的推送过来。在非交易时间段,经常会接收脏数据,脏数据通常是浮点数最大值。

行情数据落地时,如果直接在OnRtnDepthMarketData中将行情数据写入到CSV中,一旦IO写磁盘操作变多便会和API底层接收行情数据相互干扰,轻则写入文件中的数据落后于实时数据,重则直接导致订阅行情进程宕机。

解决方案有两种,一种是将SPI线程收数据和行情数据落地写入CSV两个操作隔离开来,SPI线程将收到行情数据写入队列,另起一个线程从队列里读取数据写入CSV;另一种是线收取完成切片的所有合约行情数据,然后再落地行情数据,由于切片行情数据收取完成后到下一个切片推送时存在数百ms的时间间隔,可以用于数据落地。

行情数据中有些字段是无效值,CTP统一用double的上限值1.7976931348623157e+308表示,如期货合约的PreDelta、CurrDelta、ClosePrice、SettlementPrice。

2、CTP行情推送规则

CTP行情推送规则为:

(1)1秒2次快照行情。

(2)有更新才推送,没有更新的合约推送。

(3)第一次连接后推送初始行情。

CTP推送行情的基本原则是每秒推送两次,但推送时间(毫秒级)并不是严格的000、500,即有可能推送时间是300、800。

通过CTP API连上CTP系统后,CTP会惯例的推送一笔最近的行情数据,用于提醒客户端当前市场是否有行情。

开盘前的集合竞价撮合阶段,交易所也会推送行情。开盘时刻的行情的时间戳可能大于等于500,也可能小于 500。

互联网环境下,开盘后CTP会推送合约的状态(如开盘后,合约状态更新为连续交易),消息推送时间与开盘后第一笔行情时间几乎是重合的。
