Hi @mojtaba.danai

Please bear in mind that Elektron Realtime carries in excess of 50 millions RICs (at the time of writing) - so would probably want to filter the list of RICs to specific exchanges and asset class / instrument type etc. This is possible using the BDS mechanism mentioned in a post above - but requires for your local market data team to be able to access the Elektron Edge device console to make config changes.

An article on how to use the BDS facility should be available on this website in the next few days.

UPDATE: Article now available How can I get a list of all RICs available on Elektron RT?

Refer to EMA RDM Usage Guide, there is the Symbol List domain which provides access to a set of symbol names, typically from an index, service, or cache. For example, .AV.O is a symbol list RIC for Top 25 By Volume of NASDAQ Capital Market Consolidated.

Therefore, you can EMA to subscribe to symbol list RICs to get the list of items. However, as I know, there is no symbol list RIC for all items in Elektron service.

Fortunately, Thomson Reuters Elektron Edge device does have a feature called Broadcast Data Stream (BDS) which allows users to define user-defined symbol list RICs matching a set of specified criteria. For example, you can define a symbol list RIC in the Elekton Edge device for all RICs in the Eurex exchange.

For more information regarding BDS, please contact your Thomson Reuters' account team.

In Elektron APIs, Symbol List is a domain. RICs in this domain provides access to set of symbol names, typically from an index, service, or cache.

You need to contact the content team to get a Symbol List RICs which can provide the required list of items. You can use Contact Us to directly contact the content team.

For example, if you would like to get a list of RICs for Top 25 By Volume of NASDAQ Capital Market Consolidated, you need to subscribe to .AV.O with the symbol list domain. The 270_SymbolList example is available in the EMA package demonstrates basic usage of the EMA library for accessing and parsing of OMM SymbolList data. The output of this example is:

Item Name: .AV.O
Service Name: ELEKTRON_DD
Item State: Open / Ok / None / 'All is well'
