Cost basis discrepancies?

Hello,
i’ve noticed weird behaviour regarding cost basis that I can’t explain : surely i’m missing something ?

Example :

=> Why is the cost basis so different, whereas the amount is exactly the same between the 2 tx, and the 2 tx are so close in time ?

This type of situation happens a lot in my Koinly timeline, so I’m worried my end result may be way off.

Can someone explain the rational here ?

I’m still interested in an explanation if someone from support is available. It might be just me who didn’t understand something really basic; or it might be something awfully wrong with my timeline, I don’t know at that point.

What cost basis method are you using?

I’m using PFU / France.
And “Wallet based cost tracking” is disabled.

Sorry, I have no idea how PFU works.

Do you have other holdings of SXP? Cost basis might’ve been transferred using other SXP holdings.

I don’t have any other SXP holdings, these are all my SXP holdings, which is why i’m puzzled about the cost basis varying from one line to the other. Hope someone from support will be able to help me understand what’s the logic here.

ici personne de koinly ne répondra…
visiblement les documents générés sont complétement erronés…
a priori les transactions en fiat donnent un “cost basis” complètement délirant…
il semble que le calcul “PFU” ne donne pas le bon calcul pour le coût des transactions et donc tous mes transactions en fiat donnent des moins values…
bizarre…

Salut tu peux détailler sur les erreurs que tu observes ? J’arrive toujours pas à savoir si koinly me sort des résultats fiables ou pas (quoi que les anomalies que j’ai soulignées me mettent un gros gros doute)
