I use Reuters data and noticed that today 5-3
there is a huge spike on the SPY candle that is not correct according to other sources. Does Reuters correct these bad prints the next day?

Yes bad data is usually corrected automatically the next time you download. I believe it goes back to the last 30 days ...

Thanks Patrick. Do I still have to go into the downloader and delete the bad number and manually correct the error? Or does the new data take care of that in the downloader. I seem to remember a similar situation a few months ago on QQQQ that stayed there until I manually fixed it.

If we are talking about bad data, your next download will fix automatically unless the bad data dates from over 30 days ...
So you do not need to go and manually fix the data.

When you talk about QQQQ you might refer to symbol changes.
QQQQ use to be QQQ and you need to make the symbol changes manually.
