I was previously using IB's intraday data for SPY ( upto and including May 17 2024) and recently switched to Bloomberg's intraday data for SPY (from May 20 2024 onward). When I tried charting the data, the charts would populate upto May 20 2024 but would not go further back. Checking on the Historical Data window, all the data from both IB and Bloomberg is all there.
Can you please advise how I can "merge" the data together? I've tried restarting NT8 as well.

Kay Wai
