-- C++如何获取更多的历史数据和历史指标数据

如下代码，我需要获取15分钟K线的数据和MACD，SAR指标数据，但最多只能获取到14个，请问有什么办法能获取更多的吗？

STKINDIEX_EXTFUN_ST stFormulaData = {0};

stFormulaData.m_nMarket = \'JZ\';

strcpy(stFormulaData.m_szLabel,"IF06"); //调用浦发银行数据

memset(stFormulaData.m_szIndiName, 0, 256);

//strcpy(stFormulaData.m_szIndiName,"MA.MA2(5,10,20,60)"); //调用MA指标的MA2指标线

strcpy(stFormulaData.m_szIndiName,"SAR.SARV"); //调用MA指标的MA2指标线

stFormulaData.m_nCoType = 0;

stFormulaData.m_nPeriod = 2;

//stFormulaData.m_nPower = 1;

stFormulaData.m_nDataNum = 1000; //调用最近1000周期数据

//通过扩展函数调用

STKINDIEX_EXTFUN_DATA_RET * pSARData = (STKINDIEX_EXTFUN_DATA_RET*)g_pMainFormework->ExpandFunction(&stFormulaData,STKINDIEX_EXTFUN);

memset(stFormulaData.m_szIndiName, 0, 256);

strcpy(stFormulaData.m_szIndiName,"MACD.DEA"); //调用MA指标的MA2指标线

STKINDIEX_EXTFUN_DATA_RET * pMACDData = (STKINDIEX_EXTFUN_DATA_RET*)g_pMainFormework->ExpandFunction(&stFormulaData,STKINDIEX_EXTFUN);

PCALCINFO stData = {0};

stData.m_dataType = MIN15_DATA;//日线

//stData.m_bIsPow = 1; //是否复权

stData.m_wMarket = \'JZ\';

strcpy(stData.m_szLabel,"IF06"); //读取600000 浦发银行数据

if(g_pMainFormework->GetDataInfo(&stData)==0 || pSARData->m_nDataCount <= 0 || pMACDData->m_nDataCount <= 0)

{

AfxMessageBox("调用失败。");

return;

}

CString strMsg;

strMsg.Format("%d, %d, %d",stData.m_nNumData,pSARData->m_nDataCount,pMACDData->m_nDataCount);

AfxMessageBox(strMsg);

int nSize = pSARData->m_nDataCount;

if(nSize > pMACDData->m_nDataCount) nSize = pMACDData->m_nDataCount;

if(nSize > stData.m_nNumData) nSize = stData.m_nNumData;

CString strAllData;

for(int i=0; i<nSize; i++)

{

CString strOneData;

COleDateTime time = pSARData->m_pValues[i].m_timeDate;

strOneData.Format("%s,%f,%f,%f,%f,%f,%f,%f\\n",time.Format("%Y/%m/%d %H:%M:%S"),stData.m_pMainData[i].m_fOpen, stData.m_pMainData[i].m_fHigh, stData.m_pMainData[i].m_fLow, stData.m_pMainData[i].m_fClose, stData.m_pMainData[i].m_fVolume, pSARData->m_pValues[i].m_dbValues, pMACDData->m_pValues[i].m_dbValues);

strAllData += strOneData;

}

CFile file;

file.Open("D:\\\\data.txt",CFile::modeCreate|CFile::modeReadWrite);

file.Write(strAllData,strAllData.GetLength());

file.Close();

AfxMessageBox("OK");

return;
