I have been trying to pull time series history for the ‘TRPC Coal API2 Yearly Dec 2020’ using time intervals of sub 30 minutes. It mentions that the data is limited to the last 3 months. Is this also the case if I use the Eikon API to retrieve the data? Is it possible to get a longer history for the more granular data?
I'm afraid not. Through Eikon you can get the max of 1 year of price history in 30 minute summarization and the max of 90 days of tick history or price history in sub 30 minute summarization.
Longer intraday price history is available through Thomson Reuters Tick History product.
