Hi I have been logged in in the past 14 hours and noticed 2 wired issues that I would Like to find out more details:
1) I registered the OnTicksReceivedEvent event and after log in to the OEC API, I did recived notification every time the that a tick received, but according to my logs at a certain time ticks were no longer received. In this case my system identify this situation and re-connects. and nonetheless the system keeps not getting any tick notification. this goes on and on.

My question:
What is the cause for not getting ticks in the first place? communication issues? do I need to have a good connection at all time?
Why after re-connect I still don't receive any ticks?

2) I also subscribed to OnDOMChangedEvent, and I do not get any notification on DOM, only ticks why is that?

10x,
Yogev

Our server logs show a bunch of reconnections starting from 21:12 up to 01:40 CST without any price requests from client side. Duration of each connected session was about 3-4 minutes

Question 1:

I used the SubsribeTicks and SubscribeDOM and sometimes I don't receive DOM notification,
But ticks notification is received. meaning that I used the subscribed DOM and Ticks.
Received some DOM and Ticks notification, and then stooped to receiving DOM notifications.

Question 2:
Do the API server works different from Production/Simulation, is this issue might occurs if I am working on Live??

Question 3:
Could you please specify the correct order of Subscribing to Ticks And DOM notifications?

Question 4:
If I am using the disconnect, should I unsubscribe first? or is it OK to just Disconnect?

Hello,

1.
DOM and ticks subscriptions are independent ones. Please specify timestamp of issues with stopping DOM notifications and I check server logs.

2.
API works the same way as Production/Simulation. If the reason of issue is in our server, it can occur in all three environments

3.
There is no any special order for subscribing to ticks and DOM

4.
Just Disconnect is OK.
