- Create several charts and link them by instrument (pick a colour)
- Choose a Forex pair, say, EURUSD
- Set chart timeframes to, say, 1, 5, 15, 60 and 240 minutes and Daily
- Change the instrument (to, say, AUDUSD)
- All the minute-based charts update, as expected. The Daily chart clears but does not update and needs All Historical Data to be Reloaded manually.
Thanks.

... but it appears it is not limited to Daily charts. I have now seen it on minute-based charts of different timeframes.
