That is certainly not expected from a users POV. I took a look at the raw data provided by stooq.pl for the day in question and here are the results:

thb at thb-nb:~/tmp$ curl 'https://stooq.pl/q/d/l/?s=EURHUF&d1=20180502&d2=20180502&i=d'
Data,Otwarcie,Najwyzszy,Najnizszy,Zamkniecie
2018-05-02,314.07,314.721,312.978,314.49

thb at thb-nb:~/tmp$ curl 'https://stooq.pl/q/d/l/?s=HUFEUR&d1=20180502&d2=20180502&i=d'
Data,Otwarcie,Najwyzszy,Najnizszy,Zamkniecie
2018-05-02,0.31836,0.31951,0.31774,0.31796

So how should KMyMoney know, that in one case the numbers are too big by a factor of 100?

Yes, but it's the accuracy which is provided by the server, so nothing KMyMoney can do about.

Any idea of how to improve the situation?
