Hi @jwlee08,

You are mixing two API calls. Either stick with Eikon Data API (tr in your code), or use RD Library calls. For getting timeseries data with EDAPI use get_timeseries API call.

You can also use the get_data API to get limited historical data for fields that support history. PRIMACT_1 and TRDPRC_1 are real time functions and do not support history.
