VC6.0 如何编写大智慧飞狐等股票dll函数举例

编写 zig(c,10) 函数

 

源码如下

 

__declspec(dllexport) int WINAPI ZIG(CALCINFO* pData)

{

      float c2,c3;

      if ( pData->m_pfParam1 &&                //参数1有效

         pData->m_nParam1Start<0 &&            //参数1为常数

         pData->m_pfParam2==NULL )            //仅有一个参数

    {

        float fParam = *pData->m_pfParam1;

       int nPeriod = (int)fParam;            //参数1

        if(nPeriod>0)

        {

            int i, p;

            float vclose;

            p=0;

            for ( i =0; i < pData->m_nNumData; i++ ) //全部清零

            {

                pData->m_pResultBuf = 0;

                c2=pData->m_pData.m_fClose;

                c3=pData->m_pData.m_fClose;

            }

            for(i=1;i<pData->m_nNumData;i++)

            {

                vclose=pData->m_pData.m_fClose;

                if(p==0 || p==1)

                {

                    if(vclose >= c2*(1-(float)nPeriod/100))

                        c2= c2>=c2 ? c2:c2;

                    else

                    {   p=-1;

                        pData->m_pResultBuf=-1;

                    }

                }

                if(p==0 || p==-1)

                {

                    if(vclose <= c3*(1+(float)nPeriod/100))

                        c3=c3>=c3 ? c3:c3;

                    else

                    {    p=1;

                        pData->m_pResultBuf=1;

                    }

                }

               }

        }

    }

    return 0;

}
