鼎元C++程序化交易系统教程【test.cpp文件解读】
以一个套利策略全部程式码为例：[url]http://www.qhlt.cn/thread-158982-1-1.html[/url]；下面解构一下策略模板：
1、库引用：[code]#include "pch.h"
#include "test.h"
#include <vector>
#include <windows.h>
#include <fstream>
#include <stdio.h>
#include <mmsystem.h>
#include <thread>
#pragma comment(lib,"winmm.lib")
using namespace std;[/code]2、外部文件引用：[code]extern "C" __declspec(dllexport)Interface * create(HWND hw, string sName, string sPeriod, string sInst)
{
return new test(hw, sName, sPeriod, sInst);
}
extern "C" __declspec(dllexport)void destory(Interface * p)
{
delete p;
}[/code]3、细碎功能部分：
字段分割：[code]vector<std::string> split(std::string str, std::string pattern)
{
std::string::size_type pos;
std::vector<std::string> result;
str += pattern;
int size = str.size();
for (int i = 0; i < size; i++)
{
pos = str.find(pattern, i);
if (pos < size)
{
std::string s = str.substr(i, pos - i);
result.push_back(s);
i = pos + pattern.size() - 1;
}
}
return result;
}[/code]其它细碎功能[code]test::test(HWND hw, string sn, string sp, string si)
{
hwnd = hw;
sName = sn;
sPeriod = sp;
sInst = si;
// SetTimer(NULL, 0, 1000, (TIMERPROC)TimerProc);

double test::avg(string period, string inst, int num)
{
double d = 0;
int n = 0;
map<string, TKVALUE>::reverse_iterator it;
// InsertLog(to_string(mapK[period][inst].size()));
for (it = mapK[period][inst].rbegin(); it != mapK[period][inst].rend(); ++it)
{
d += it->second.dClose;
n++;
if (n >= num)break;
}
return d / n;
}
double test::highest(string period, string inst, int num)
{
double d = 0;
int n = 0;
map<string, TKVALUE>::reverse_iterator it;
for (it = mapK[period][inst].rbegin(); it != mapK[period][inst].rend(); ++it)
{
if (d < it->second.dHigh)d = it->second.dHigh;
n++;
if (n >= num)break;
}
return d;
}

{
double d = 0;
int n = 0;

for (it = mapK[period][inst].rbegin(); it != mapK[period][inst].rend(); ++it)
{
if (d == 0)d = it->second.dLow;
if (d > it->second.dLow)d = it->second.dLow;

}
return d;
}

{

int r = 0;
map<string, TKVALUE>::reverse_iterator it;
// InsertLog(to_string(mapK[period][inst].size()));
for (it = mapK[period][inst].rbegin(); it != mapK[period][inst].rend(); ++it)
{

if (r <= ref)continue;

if (n >= num)break;
}
return d / n;
}
double test::highest1(string period, string inst, int num, int ref)
{

}
return d;
}
//公式函数计算集合结束...................................................................................................................................................[/code] 5、获取系统时间功能[code]string GetSystemTime()
{
SYSTEMTIME m_time;
GetLocalTime(&m_time);
char szDateTime[100] = { 0 };
sprintf_s(szDateTime, "%02d:%02d:%02d.:%03d", m_time.wHour, m_time.wMinute, m_time.wSecond, m_time.wMilliseconds);
string time(szDateTime);
return time;
}[/code] [color=Red][b]6、交易界面时间设置及面板中策略参数的获取功能[/b][/color]
示意图参考：[url]http://www.qhlt.cn/thread-158984-1-1.html[/url]；[code]/// <summary>
/// 以下开始
/// </summary>
string timeStart = "08:50:00";
string timePause = "15:32:00";
string timeResume = "20:50:00";
string timeStop = "02:32:00";
string state = "stop";
void test::InitParm()
{
TDLLPARM t;
//Name 参数名, Value 默认值, Explain 参数说明, tend 表示一个参数结束
t.Name = "第一腿合约"; t.Value = "hc2210"; t.Explain = "第一腿合约代码"; tend(t);
t.Name = "第二腿合约"; t.Value = "rb2210"; t.Explain = "第二腿合约代码"; tend(t);
t.Name = "第一腿买卖"; t.Value = "0"; t.Explain = "0位买入1位卖出"; tend(t);
t.Name = "第一腿开平"; t.Value = "0"; t.Explain = "0为开仓1位平仓3位平今仓4位平昨仓"; tend(t);
t.Name = "交易数量"; t.Value = "1"; t.Explain = "下单交易数量"; tend(t);
t.Name = "条件价差"; t.Value = "100"; t.Explain = "条件价差入场值"; tend(t);
t.Name = "条件价差方向"; t.Value = "1"; t.Explain = "1为大于，-1为小于"; tend(t);
t.Name = "交易滑点值"; t.Value = "0"; t.Explain = "交易滑点值"; tend(t);
t.Name = "是否重发"; t.Value = "1"; t.Explain = "0不重发，1重发"; tend(t);
t.Name = "时间间隔"; t.Value = "5"; t.Explain = "委托后不成交撤单时间间隔 s "; tend(t);
t.Name = "挂单量"; t.Value = "50"; t.Explain = "达到最小挂单量才下单"; tend(t);
end();
}[/code]这里面的参数要和头文件里面的设置对应起来（最底部的var声明那里），头文件链接：[url=http://www.qhlt.cn/thread-158981-1-1.html]http://www.qhlt.cn/thread-158981-1-1.html[/url]；

InsertLog(" 期货套利策略开始运行 ");
}[/code]点击交易界面中点击“停止”[img]http://p.algo2.net/2024/0926/3768ba3817af1.png[/img]按钮后加载项目[code]void test::OnStop()
{
OnState("stop");
sound("sound\\stop.wav");
InsertLog(" 期货套利策略停止运行 ");
}[/code] [color=Blue]7、核心策略设计（如何进场，如何出场，如何止盈，如何止损）[/color]（因为程式码太长，另建贴存放，链接：[url]http://www.qhlt.cn/thread-158986-1-1.html[/url]；） 8、跟交易相关的发单，撤单，重发，优先平今或优先平昨等，跟策略相关不大，不建议改动（因为程式码太长，查看链接：[url]http://www.qhlt.cn/thread-158985-1-1.html[/url]；） 总结：
1、配置文件类程式码无须变动。
[color=Red]2、页头文件，公式计算（4），交易界面设置与变量参数设置（6），核心策略设计（7）是重点或者说经常变动部分，在平时的策略化交易过程中会不时的修改与设计。后面的策略教学中也以这三个部分为主。[/color]
