Hi Nurhaz,
In Version 63 onwards, you can use Periodic Condition >> Custom as in this link https://support.seeq.com/kb/R63/cloud/what-s-new#id-(R63)What'sNew?-CustomfrequencyperiodicconditionswithoutFormula
If you are in older version, at the Formula tool you can write as below:
periods(5d)
To Create a rolling linear forecast on data, we can use the formula tool:
$signal.forecastLinear(7d,3d)
As of R63 you can also use the ForecastArima function in Seeq Formula as well to create a rolling forecast. Please see the following knowledgebase article for more information on how to use ForecastArima: https://support.seeq.com/kb/latest/cloud/best-practices-for-using-forecastarima
Please do have a look at few other discussions as below links that applied the forecastlinear() function.
The cumulative of time as shown in Step 3 can be simplified to timesince($condition,1min).
