In Codebook, the client can use Eikon Data API, Refinitiv Data Platform Library, or Datastream Webservice to retrieve historical data.
There are examples in the __Examples__ folder in Codebook that demonstrate how to get historical data.
hi @MouyaHana.Soriano ,
If you mean connect to Tick History data using Codebook, I am afraid the user cannot do that. (please correct me If I understand the question wrong)
I tried to download the sample Python code from Refinitiv Tick History (RTH) - REST API and execute it using Codebook but got error 403 Forbidden, which means this connection is blocked by Codebook
I'd suggest the user access the data on their Python environment, as Codebook isn't allowing some connection.
