C++如何获取更多的历史数据和历史指标数据 [金字塔]
- 咨询内容：
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;
- 金字塔客服： 打开图表看下本地数据是否齐全。
有思路，想编写各种指标公式，程序化交易模型，选股公式，预警公式的朋友
