I track the following symbols on the Frankfurt Börse:
ALi1
DHL
HAG
RHM
RWE
SIE
And starting this morning, some but not all of the symbols are failing. Ali1, DHL and RWE are no longer found... meanwhile HAG, RHM and SIE continue to work both with exchange "FRA" and with "ETR".
For Almonty I've resorted to tracking that share on TSE in CAD.
For DHL and RWE I am tracking the share price on the Vienna exchange, so I don't get errors in all my formulas. But the prices are not really accurate as I hold the shares listed on XETRA.
Just wondering if anybody knows whether this is a systemic change, or maybe a temporary error.
