I want to do a summation of a ticker price series, but reset it on a new session. Is there a built-in study that will do this?

Hi Mike

take a look to :
Technical Studies Reference - Sierra Chart

LOL how embarrassing. I found Summation but didn't see the Cumulative one, and then when I created the thread title I thought I would be more descriptive by saying cumulative but didn't bother looking at Sierra for an indicator that started with that. It seems like the two studies are identical, except one can reset on new session. I'm not sure why there needs to be two studies, instead of just one with the reset option. (Cumulative Sum of Study vs Summation).

Works great.

Mike

And now I have a cumulative tick reset on new session.

Hi All

This is my 2 cents for someone who might be interested in.

 

Code

#include "sierrachart.h" SCDLLName("bm_cv6u"); SCSFExport scsf_bm_cv6u(SCStudyInterfaceRef sc) { if (sc.SetDefaults) { sc.Input[0].Name = "Source #1 to summ "; sc.Input[0].SetChartStudySubgraphValues(1,0,4); sc.GraphName = "bm_cv6u"; sc.StudyDescription = "bm_cv6u @ganz"; sc.Subgraph[0].Name = "summ"; sc.GraphRegion = 1; sc.ValueFormat = 2; sc.AutoLoop = 1; sc.FreeDLL = 0; return; } SCGraphData src1Array; int src1Chart = sc.Input[0].GetChartNumber(); int src1Study = sc.Input[0].GetStudyID(); int src1StudySubgraph = sc.Input[0].GetSubgraphIndex(); sc.GetStudyArraysFromChartUsingID(src1Chart, src1Study, src1Array); SCFloatArrayRef src1ArrayData = src1Array[src1StudySubgraph]; double& CumulativeSummation = sc.PersistVars->d1; SCDateTime StartDateTimeOfDay; StartDateTimeOfDay.SetTime(sc.StartTimeOfDay); StartDateTimeOfDay.SetDate(sc.BaseDateTimeIn[sc.Index].GetDate()); if(sc.BaseDateTimeIn[sc.Index] == StartDateTimeOfDay || (sc.BaseDateTimeIn[sc.Index-1] < StartDateTimeOfDay && sc.BaseDateTimeIn[sc.Index] > StartDateTimeOfDay)) CumulativeSummation = src1ArrayData[sc.Index]; else CumulativeSummation += src1ArrayData[sc.Index]; sc.Subgraph[0][sc.Index] = CumulativeSummation; return; }

Hi @slickiam

Have you coded anything that calculates the relative cumulative summation over X days? So you could examine at each time stamp how much % a subgraph has done of its cumulative average over x days.

Similar to the "Cumulative Volume Ratio",https://www.sierrachart.com/index.php?page=doc/StudiesReference.php&ID=356

So it would become the Cumulative Summation ratio.

eg
CurrentDayCumulativeSummationToTime / PriorDayAverageCumulativeSummationToTime
