I heard a rumor that it's not available yet, so please kindly clarify it.
Yes, Eikon .NET API can be used to retrieve the real-time and 90 days Tick via Eikon. It was mentioned in this page:
You can also access the examples and tutorials from:
Thank you for your prompt response and I understand that only .NET API supports it and COM API doesn't.
Please let me ask one more related question.
Regardless of the number of ticks(=trades), can the whole past 90-day historical tick data can be retrieved via the API since I believe that to when historical tick data of a RIC dates back on the Eikon Chart App depends on the number of the ticks as you can see in the attached and that there's a restriction that the max number of ticks we can retrieve via Eikon Chart App is 6,000 ticks?tick-chart-on-eikon-20170323.zip
If the API would enable users to access the entire 90-day historical tick data regardless of the number of the ticks, that would be amazing!
The limit is actually 60K timeseries records, not 6K, and it does apply to all consumers of timeseries data in Eikon including Eikon .NET SDK. However this is the limit for a single request. Using Eikon .NET SDK you can send as many requests as you need (within reasons), and you can use the timestamp of the earliest record returned in previous request as a criteria for the next request, thus requesting the next batch of 60K records, and so on until you retrieve full 90 days history available.
