If you set up your watch list before Radar Relay migrated to the new canonical WETH (January 25th 2018) the price will still be accurate in the watch list but the link will no longer pull up that trading pair.


The links are connected to the old WETH contract. 

Remove the pair from your watch list by clicking unwatch.


Then re-add the pair to the watch list to create a watch list with active links to the trading pair.
