ACSIL control of chart bar period and days to load

Is there a way from ACSIL to control the number of days to load and the bar period of a chart?
I've tried doing it with the code shown below using a custom button but nothing changes in the chart.
None of the days to load or bar period parameters change in the chart.
I know the button is working correctly from message logs.
Also, I am currently using SC built in bar period buttons but want to add more functionality like number of days to load, etc.


ACSIL study code snippet:

n_ACSIL::s_BarPeriod NewBarPeriod;

// assign current chart parameters
sc.GetBarPeriodParameters(NewBarPeriod);

// change the parameters i want to change
NewBarPeriod.ChartDataType = INTRADAY_DATA;
NewBarPeriod.IntradayChartBarPeriodType = IBPT_DAYS_MINS_SECS;
NewBarPeriod.IntradayChartBarPeriodParameter1 = 1 * 60; // 1 minute * 60 sec/min

// Set the new bar period parameters
sc.SetBarPeriodParameters(NewBarPeriod);
sc.DaysToLoadInChart = 10;

This should work fine. We are testing this code.

Were you able to get these functions and this code to work on your system?
If so, do you have any suggestions for how I can get it to work?

This works:
sc.DaysToLoadInChart = 10;

There was a problem with this function:
sc.SetBarPeriodParameters(NewBarPeriod)

We solved that problem with that function. Use the latest prerelease for the corrections.

Is it possible to control the bar period from a spreadsheet study?

No, it is not. You need to use ACSIL to accomplish this.

Hi... I used the same code:

....
sc.GetBarPeriodParameters(NewBarPeriod);
NewBarPeriod.IntradayChartBarPeriodType = IBPT_RANGE_IN_TICKS_STANDARD;
if (NewBarPeriod.IntradayChartBarPeriodParameter1 != r1)
{
NewBarPeriod.IntradayChartBarPeriodParameter1 = r1;
sc.SetBarPeriodParameters(NewBarPeriod);
}

in Live it works fine, but not in Replay. Do you know wy?

Increase the replay speed so there is some activity in the chart so the study function is called. Maybe that is the problem.

What we want you to do is to test this study function below. Build it and apply the study to an Intraday chart and do a replay. The chart bars will change to 5 minutes. During the replay change the chart bars to 1 minute per bar and then they should automatically change back to 5 minutes.

SCSFExport scsf_BarPeriodParametersTest(SCStudyInterfaceRef sc)
{
  if (sc.SetDefaults)
  {
    // Set the configuration and defaults.

    sc.GraphName = "Bar Period Parameters Test";

    sc.AutoLoop = 0;
    sc.GraphRegion = 0;
    sc.UpdateAlways = 1;

    return;
  }

  n_ACSIL::s_BarPeriod BarPeriod;
  sc.GetBarPeriodParameters(BarPeriod);
  if (BarPeriod.ChartDataType == INTRADAY_DATA && BarPeriod.IntradayChartBarPeriodType == IBPT_DAYS_MINS_SECS)
  {
    int SecondsPerBar = BarPeriod.IntradayChartBarPeriodParameter1;
  }

  SCString DebugString;
  DebugString.Format
    ( "Bar Period type=%d, parameters={%d, %d, %d, %d}."
    , BarPeriod.IntradayChartBarPeriodType
    , BarPeriod.IntradayChartBarPeriodParameter1
    , BarPeriod.IntradayChartBarPeriodParameter2
    , BarPeriod.IntradayChartBarPeriodParameter3
    , BarPeriod.IntradayChartBarPeriodParameter4
    );
  sc.AddMessageToLog(DebugString, 0);

  if (BarPeriod.ChartDataType != INTRADAY_DATA
    || BarPeriod.IntradayChartBarPeriodType != IBPT_DAYS_MINS_SECS
    || BarPeriod.IntradayChartBarPeriodParameter1 != 300)
  {
    n_ACSIL::s_BarPeriod NewBarPeriod;
    NewBarPeriod.ChartDataType = INTRADAY_DATA;
    NewBarPeriod.IntradayChartBarPeriodType = IBPT_DAYS_MINS_SECS;
    NewBarPeriod.IntradayChartBarPeriodParameter1 = 300;// 300 seconds per bar which is 5 minutes

    //Set the bar period parameters. This will go into effect after the study function returns.
    sc.SetBarPeriodParameters(NewBarPeriod);
  }
}

hi... Thank yuo for the code. I Find the Problem now. but i dont know what is wrong. The Problem is in this case....

{.....}

SCDateTime& pLastCalculationDateTime = sc.GetPersistentSCDateTime(50);
SCDateTime& pLastRangeChangeDateTime = sc.GetPersistentSCDateTime(51);

if (CurrentDateTime - pLastRangeChangeDateTime > (Input_ChTime.GetInt() * SECONDS))
{
.....
//calculation and Range-Change....
}

pLastCalculationDateTime = CurrentDateTime;

{.....}

-------------------

when i make the Time-questions extract from code, then it works on replay to, with... only in realtime...
can you help me?

SCDateTimeMS CurrentDateTime   = sc.GetCurrentDateTime();

We are not understanding this and we do not provide programming help. You need to understand that you know your code best. We cannot get involved with your own code. Here is the documentation for sc.GetCurrentDateTime
sc.GetCurrentDateTime()

hi... i find it....

if (sc.IsReplayRunning())
CurrentDateTime = sc.CurrentDateTimeForReplay;
else
CurrentDateTime = sc.CurrentSystemDateTime;

Thanks. its solved...
