Missing data upon subscription on the public test feed

Added by fredrik 6 months ago

The public test feed do not send any data to the client upon subscription on price or depth (during stock market opening hours). However, hearbeat works well!
This was tested with the python3 test program (https://github.com/nordnet/next-api-v2-examples)

I think the issue is that its not possible to create an order in the test system due to some bug. The server responds with a 500 Internal Server Error and has done so for the last ~30 days. Since no-one can enter orders, the feed will just deliver heartbeats.

Fredrik, are you also getting a 500 Internal Server Error when entering a new order?

The test market is connected to the Nasdaq Test Market. So even if you cannot enter orders you should see price ticks. I have tested and I see price ticks.

Yes I see the same error when entering an order (500 Internal Server Error).

My experience is that everything was working fine until I posted "Missing heartbeat on the public feed [FIXED]" (https://api.test.nordnet.se/boards/2/topics/3003). The hearbeat works fine now but the subscription is still silent. I tested the same thing on a new account (created today) but I get the same behavior.

@Nordnet_Support: Can I do something to help you in your troubleshooting?

One observation that might help in the troublehshooting. The server response is OK with an appropriate reply message if the format of the order request is not correct, such as using accno=0.
It feels like there are issues with the connection to the Nasdaq Test Market or issues with data forwarding from the Nordnet Test Server to at least some clients.

Missing data have seriously compromised inferences from clinical trials.1 For example, editorials in the Journal have noted how missing data have limited the ability to draw definitive conclusions from weight-loss trials6 or could lead to incorrect inferences about drug safety https://www.mcdvoice.ltd/
