Hello ... Kind of basic, but I couldn't find it ... For time bars only: is there a sc.function for the number of bars per day (based on the settings), and a sc.function for the number of bars since midnight for a particular index? (So if you give an index of a bar 3 days ago, the function will calculate the number of bars from midnight three days ago up to that particular index) Anyway, my goal is to calculate the average volume for each same bar at the same time of each day. In other words, the average volume for a bar going back each day, indexed by the number of bars since midnight (or otherwise the first bar of the days). |

We will see if we can put together a function for this quickly.

Thanks a lot. This worked for me already ... SCSubgraphRef AvgVolumePerIndex = sc.Subgraph[9]; SCFloatArrayRef SumVolPerIndex = AvgVolumePerIndex.Arrays[1]; SCFloatArrayRef nSumVolPerIndex = AvgVolumePerIndex.Arrays[2]; int MaxPerBarIndex=0; int TO=sc.IndexOfLastVisibleBar; int FROM=sc.IndexOfFirstVisibleBar-100; for(int n=FROM; n <= TO; n++){ int nYear,nMonth,nDay,nHour,nMinute,nSecond; SCDateTime nDate = sc.BaseDateTimeIn[n]; nDate.GetDateTimeYMDHMS(nYear,nMonth,nDay,nHour,nMinute,nSecond); int nLastMidNight=sc.GetContainingIndexForSCDateTime(sc.ChartNumber,nDate.SetDateTimeYMDHMS(nYear,nMonth,nDay,0,0,0)); int PerBarIndex=n-nLastMidNight; //AvgVolumePerIndex[n]=PerBarIndex; if(sc.Volume[n]>0){ SumVolPerIndex[PerBarIndex] = SumVolPerIndex[PerBarIndex]+sc.Volume[n]; nSumVolPerIndex[PerBarIndex] = nSumVolPerIndex[PerBarIndex]+1; } if(PerBarIndex>MaxPerBarIndex)MaxPerBarIndex=PerBarIndex; } for(int n=FROM; n <= TO; n++){ int nYear,nMonth,nDay,nHour,nMinute,nSecond; SCDateTime nDate = sc.BaseDateTimeIn[n]; nDate.GetDateTimeYMDHMS(nYear,nMonth,nDay,nHour,nMinute,nSecond); int nLastMidNight=sc.GetContainingIndexForSCDateTime(sc.ChartNumber,nDate.SetDateTimeYMDHMS(nYear,nMonth,nDay,0,0,0)); int PerBarIndex=n-nLastMidNight; if(SumVolPerIndex[PerBarIndex]>0 and nSumVolPerIndex[PerBarIndex]>0){ AvgVolumePerIndex[n]=SumVolPerIndex[PerBarIndex]/nSumVolPerIndex[PerBarIndex]; } else AvgVolumePerIndex[n]=0; pVolMA[n]=AvgVolumePerIndex[n]; } for(int z=0; z <= MaxPerBarIndex; z++){ SumVolPerIndex[z]=0; nSumVolPerIndex[z]=0; } |
