I looked for trades for a card, and when I select one of the person on the list, sometimes they actually have no compatible trade with me.
For example, I looked for Méga-Camérupt ex (4 diamonds), I clicked on one of the 2 people listed and I got this :
I don’t have any 4 diamonds card that the other person want.
Can you PM me your and the other person friend IDs? I’ll try to debug that.
I received a trade request without a card to be sent from my side and it let me choose if I wanted to trade anything, could it be that is a new trading feature?
Yep 
I don’t remember seeing the announcement, but it’s a nice enhancement!
Found the bug, the list search did not correctly take into the account per card wanted amounts. Changes will hit the site when Marcel approves them. Thanks for reporting!
The fix has been deployed
I still have the issue when I search for 1 star matches, in both Any Language and English.
My Friend ID 7718174577174901
Cards I was searching for with the issue.
☆ B4-157 - Lileep
☆ B4-158 - Kricketune
☆ B4-175 - Dragonair
☆ B4-176 - Noivern
☆ B4-177 - Cyclizar
Examples where it suggests trades but no cards available:
☆ B4-158 - Kricketune > 2033451106256901, 0946056537271045, 9175206361808977
☆ B4-176 - Noivern > 2033451106256901, 2323535588171378, 8790883472358694
Added some more examples with friend ids for this issue above. The fix does not appear to have resolved the issue for me.
Thanks, this is a different issue. The person that added B4 set initially set the 1 and 2 star rarities as shiny. We thought it was fixed, but it turns out not completely, and the matches algorithm still thinks that they are shinies. DB migration will be needed to fix that.
