I find stooq currency quote very comprehensive. However during the download after awhile I found error message
"Przekroczony dzienny limit wywolan"
I dont know the language but my guess is download limit have been violated.
I checked that the successful download was from the very beginning (eg. 1983) although I have specific only a few days in Amiquote 3.2 from to range.
Would appreciate comment/advices from someone with experience dealing with the above.
