思路：
1.新增一个画线函数，该函数直接读取指数的数据，然后比照分时图画出来。
2.先算指数涨幅，Y价格=股票昨日收盘价*指数涨幅。
一、实时行情
//custom extend by freeman叠加指数分时线
void CHistoryRealTime::DrawPriceVolume2(CDC* pDC)
{
DECLARE_COLOR_DEFINATION
//获取股票的最大、最小值
double dMin = 0, dMax = 0, dMaxVolume = 0;
double dLastClose = m_CurStock.GetStockInfo().m_fLast;
if (!GetMinMaxInfo(&dLastClose, &dMin, &dMax, &dMaxVolume, TRUE))//画分时线，获取昨天收盘价，当天最低价、最高价、最大量
return;
//读取指数数据
CStockInfo info;
AfxGetStockContainer().GetStockInfo("399001", &info);
CStock m_CurStock2;
m_CurStock2.SetStockInfo(&info);
// Prepare Data
// 读取本地文件
m_CurStock2.SetDatabase(&AfxGetDB());
// 取得最新行情
m_CurStock2.PrepareData(CStock::dataReport, CKData::ktypeDay, TRUE);
m_CurStock2.PrepareData(CStock::dataMinute, CKData::ktypeDay, TRUE);
// Draw Price
//CStockInfo& info = m_CurStock2.GetStockInfo();
CMinute& aMinute = m_CurStock2.GetMinute();
DWORD secNow = CSPTime::GetCurrentTime().ToStockTimeSecOrder();//获取当前时间
DWORD secStep = 60;
//x Axis
int ptr = 0;
int xPos = m_rectPrice.left;
int yPosMid = m_rectPrice.top + m_rectPrice.Height() / 2;
int yPos = yPosMid;
int yPosLast = yPos; //y 指向中间线
//画线颜色
COLORREF clrLine5 = AfxGetProfile().GetColor(CColorClass::clrCW);
DWORD dwSeconds = CSPTime::GetTradeSecondsOfOneDay();
//以60秒为步进，开始画指数分时线
for (DWORD sec = 0; sec <= dwSeconds; sec += secStep)
{
BOOL bDrawed = FALSE;
for (; ptr < aMinute.GetSize(); ptr++)
{
DWORD secTemp = CSPTime(aMinute[ptr].m_time).ToStockTimeSecOrder();
//如果如果当前分钟线>显示的时间
if (secTemp > sec)
break;
if ((long)secTemp <= (long)sec - (long)secStep)
continue;
if (aMinute[ptr].m_fNew < 1e-4)
aMinute[ptr].m_fNew = m_CurStock2.GetStockInfo().m_fLast;//昨日收盘价
int xPosNew = m_rectPrice.left + m_rectPrice.Width() * secTemp / dwSeconds;
yPosLast = yPos;
// Draw Price Line
CPen pen1(PS_SOLID, 1, clrLine5);
CPen* pOldPen = pDC->SelectObject(&pen1);
pDC->MoveTo(xPos, yPos);
//根据价格算Y抽
double dPriceNew = aMinute[ptr].m_fNew;
//计算指数涨幅
double indexDiffPercent = (dPriceNew - m_CurStock2.GetStockInfo().m_fLast) / m_CurStock2.GetStockInfo().m_fLast;
//换算成股票价格
dPriceNew = m_CurStock.GetStockInfo().m_fLast * (1 + indexDiffPercent);
if (dPriceNew <= dMax && dPriceNew >= dMin && dMax - dMin > 1e-4)
{
yPos = (int)(m_rectPrice.top + m_rectPrice.Height() * (dMax - dPriceNew) / (dMax - dMin));
if (yPos <= m_rectPrice.top) yPos = m_rectPrice.top + 1;
if (yPos >= m_rectPrice.bottom) yPos = m_rectPrice.bottom - 1;
pDC->LineTo(xPosNew, yPos);
}
pDC->SelectObject(pOldPen);
xPos = xPosNew;
bDrawed = TRUE;
}
}
}
二、历史行情
实现思路
1.备份m_CurStock 到 m_CurStockBackup
2.添加1个定时器CHistoryRealTime::OnTimer()，负责从备份的m_CurStockBackup依次填入_CurStock
3.新增一个画线函数DrawPriceVolume2(CDC* pDC); 叠加指数，该函数直接读取指数的数据，然后比照分时图画出来。
/custom extend by freeman叠加指数分时线
void CHistoryRealTime::DrawPriceVolume2(CDC* pDC)
{
DECLARE_COLOR_DEFINATION
//获取股票的最大、最小值
double dMin = 0, dMax = 0, dMaxVolume = 0;
double dLastClose = m_CurStock.GetStockInfo().m_fLast;
if (!GetMinMaxInfo(&dLastClose, &dMin, &dMax, &dMaxVolume, TRUE))//画分时线，获取昨天收盘价，当天最低价、最高价、最大量
return;
//从股票中获取选择的日K线日期
DWORD date = 0;
date = m_CurStock.GetStockInfo().m_dateHistoryReport;
//读取指数数据
CStockInfo info;
AfxGetStockContainer().GetStockInfo("399001", &info);
CStock m_CurStock2;
//设置选择的日期，会读出历史分笔数据
info.m_dateHistoryReport = date;
m_CurStock2.SetStockInfo(&info);
// Prepare Data
// 读取本地文件
m_CurStock2.SetDatabase(&AfxGetDB());
//修改指数昨日收盘价
m_CurStock2.PrepareData(CStock::dataK, CKData::ktypeDay, TRUE);
CKData& kdata = m_CurStock2.GetKData(CKData::ktypeDay);
//根据日期获取索引号
int nIndexCurrent = kdata.GetIndexByDate(date);
//取前一日索引
nIndexCurrent -= 1;
if (nIndexCurrent < 0)
nIndexCurrent = 0;
KDATA kd;
memset(&kd, 0, sizeof(kd));
//根据索引获取日K线数据，再获取收盘价
kd.m_fClose = kdata.ElementAt(nIndexCurrent).m_fClose;
info.m_fLast = kd.m_fClose;
//设置这只股票的昨日收盘价信息
m_CurStock2.SetStockInfo(&info);
// 从磁盘读取历史分笔数据
m_CurStock2.PrepareData(CStock::dataReport, CKData::ktypeDay, TRUE);
m_CurStock2.PrepareData(CStock::dataMinute, CKData::ktypeDay, TRUE);
// Draw Price
//CStockInfo& info = m_CurStock2.GetStockInfo();

//以60秒为步进，开始画指数分时线
for (DWORD sec = 0; sec <= dwSeconds; sec += secStep)
{
BOOL bDrawed = FALSE;
for (; ptr < aMinute.GetSize(); ptr++)
{
DWORD secTemp = CSPTime(aMinute[ptr].m_time).ToStockTimeSecOrder();
//如果如果当前分钟线>显示的时间
if (secTemp > sec)
break;
if ((long)secTemp <= (long)sec - (long)secStep)
continue;
if (aMinute[ptr].m_fNew < 1e-4)
aMinute[ptr].m_fNew = m_CurStock2.GetStockInfo().m_fLast;//昨日收盘价
