Problem with using FRED ##RDISPINC

Report a problem or error
1

I am having a problem when trying to run a strategy simulation. I have a buy rule of “(Close(0, PITSeries(##RDISPINC)) >= EMA(12, 1, PITSeries(##RDISPINC)))”. I am getting the error message “UnhandledExceptionHandler: EXCEPTION_ACCESS_VIOLATION”. I am not getting that error for other FRED items such as ##INDPRO, ##SALESRET. Any ideas as to the cause?

Hi Cary , looks like this operation is crashing the servers. Can you wait to try again till we take a look tomorrow? Thank you

PS. Basically if you see “UnhandledExceptionHandler” please do not rerun the operation and let us know

The issue has been resolved. You should be good to run the simulation again.

I just tried it out and it worked!. :clap: Thank you very much. What was the problem?

Revised (“PIT”) series need to be rendered to contiguous storage in order to be used by the rest of the system. In order to do this, we build checkpoints and change sets to efficiently travel forward in time, occasionally needing to ‘reset’ when data points are either added before the latest date or removed between dates.

This particular series resulted in two consecutive resets on 2003-12-23, (where 531 points preceding 2003-04-01 were removed,) and 2003-12-31, (where 267 points preceding 2003-04-01 were added back.) I needed to rearchitect the code a bit to support this condition. (Note that the goal is to model the data provided, not fix the 8 days of missing data for this series.)
