When requesting many tickers (2000+)over the API I get the following: An exception of type 'System.Runtime.InteropServices.COMException' occurred in eikonGetData.exe but was not handled in user code Additional information: ERROR #360f - AdxRtList : invalid item How can I find out which tickers are invalid/ how can I go about handling this?

Hi @amine.elkaouachi

There's no cap on the number of RICs you can use in a single instance of AdxRtList class imposed by the API. You can also create as many instances of AdxRtList class as you need. There's an overall limit on the number of RICs used to subscribe to real-time data updates. For Hosted Eikon accounts the limit is set to 2,500 RICs. If required it can be increased to 5K upon request. This limit is shared by all applications. E.g. if you concurrently retrieve real-time data for 150 RICs in Eikon application and for 850 RICs in Excel, your application will not be able to subscribe to more than 1,500 RICs. Snapshot requests, requests for fundamental and reference data do not count towards the 2,5K RICs limit. Only outstanding subscriptions to real-time data count. When you reach the limit and attempt to add subscription to another RIC, you will receive an error message saying "aggregate item limit exceeded".

When you receive an error "invalid item" this normally indicates that you used an invalid RIC, rather than that you've exhausted your subscriptions limit. You most likely get this error message when trying to extract data for an invalid RIC from AdxRtList object using Value or ListFields methods in the OnUpdate event handler. To prevent this use a_itemStatus parameter returned into OnUpdate event handler. Or check the validity of the RIC using ItemStatus property before executing Value or ListFields methods.
