Data Reliability in datastream

I'm data engineer, currently working on stacking data from Datastream API.

In data check, I have following issues in Datastream


1. Why datastream returns NULL value for non-existing future data?
- I think this data return standard need to be fixed.
for example, API without start/end date returns not only today's value, but also null value for tomorrow

2. In data ticker/field, 'VKOSPIX' / 'PI', I found out data is offed by single date.
and also, API returns non existing close price for monday, which is filled with close price of friday.

At first I guesssed the issue is about business day convention or timezone. However, I cannot understand the reason why the value is wrong with real value.

Please let me know the programing language and library that you are using. Moreover, please provide the same code for the first question.

According to the question, it looks like to be a content question. This forum is dedicated to software developers using Refinitiv APIs. We are unable to verify the content retrieved by the API.

The best resource for Datastream content questions is the Datastream support team, which can be reached by submitting queries through MyRefinitv.

I use Python, and get data through SOAP API protocol.


Same issue occurs in DatastreamPy module, which means the issue is with Datastream database itself.
