When i try to use highest or gethighest on scgraphdata from another chart, i am getting undefined results. In the below code sg0 will return -320000000000000000000000 and sg1 will return the expected result of the daily high. Can you give me a tip on how i can use a helper function to calculate gethighest in an autoloop? I have to calculate the highest price on multiple timeframes (D,Wk,Mo,Yr) so i was hoping to avoid autoloop self calculated shenanigans. If it matters I am using a 5m intraday to host the code and the 1d intraday as defined in the snippet SCGraphData DailyBars;
s_ACSOpenChartParameters OpenChartParameters; OpenChartParameters.PriorChartNumber = 0; OpenChartParameters.ChartDataType = INTRADAY_DATA; OpenChartParameters.Symbol = sc.GetRealTimeSymbol(); OpenChartParameters.IntradayBarPeriodType = IBPT_DAYS_MINS_SECS; OpenChartParameters.IntradayBarPeriodLength = 86400 ; // 1 day OpenChartParameters.DaysToLoad = 60; OpenChartParameters.SessionStartTime.SetTimeHMS(0,0,0); OpenChartParameters.SessionEndTime.SetTimeHMS(23,59,59); sc.PersistVars->i10 = sc.OpenChartOrGetChartReference(OpenChartParameters); sc.GetChartBaseData(sc.PersistVars->i10, DailyBars); int DRefChartIndex = sc.GetNearestMatchForDateTimeIndex(sc.PersistVars->i10,sc.Index); sc.Subgraph[0][sc.Index]=sc.GetHighest(DailyBars[SC_HIGH],3); sc.Subgraph[1][sc.Index]=DailyBars[SC_HIGH][DRefChartIndex]; |

I have worked around the problem using a daily chart and some GetOHLCOfTimePeriod / GetStartOfPeriodForDateTime gymnastics. If you have any other ideas, im open to it. im satisfied with this workaround, especially since i come to find the programmatic charts only allow daily bars, i have to hand calculate the intervals anyways. |

Refer to the documentation in this section here about this: http://www.sierrachart.com/index.php?l=doc/doc_ACSILRefOtherTimeFrames.php#DirectReferencing The documentation explains how to do what you want to do. And it also explains that it is not possible to get the base data arrays from another chart and then call functions like sc.GetHighest on one of those arrays. especially since i come to find the programmatic charts only allow daily bars This is definitely not the case. You can use any timeframe.

when i use OpenChartOrGetChartReference, i only have the option of DAILY and INTRADAY data bars. There is IntradayBarPeriodType for setting intraday bars, but I was not able to locate documentation on how to load a historical weekly/quarterly/yearly bar chart programmatically. How do i specify quarterly bars for a programmatically opened chart? I know i could do (365/4) day intraday chart, but i want the integrity of the historical server to ensure correct dates. My hope was to be able to programmatically open a weekly or quarterly bar chart for reference from an intraday chart, such as drawing the last quarterly high. enum ChartDataTypeEnum { NO_DATA_TYPE = 0 , DAILY_DATA = 1 , INTRADAY_DATA = 2 }; OpenChartParameters; OpenChartParameters.PriorChartNumber = 0; OpenChartParameters.ChartDataType = WEEKLY_DATA; //This is what i *thought* would be there OpenChartParameters.Symbol = sc.GetRealTimeSymbol(); OpenChartParameters.DaysToLoad = 360; sc.PersistVars->i11 = sc.OpenChartOrGetChartReference(OpenChartParameters); Date Time Of Last Edit: 2014-06-26 09:48:58

We will add support for this: how to load a historical weekly/quarterly/yearly
