The sudden, hours-long breakdown in Deutsche Boerse AG’s electronic trading system on Wednesday led to a significant drop in volumes across affected markets, adding to the summer lull and leaving some traders frustrated.

Transactions on Germany’s DAX Index tumbled 35% to the lowest level since May 25, according to data compiled by Bloomberg. In Budapest, volumes fell 47% and in Prague the decline reached 66%. The exchanges, along with those in Vienna, Zagreb and Ljubljana, share Deutsche Boerse’s T7 trading system.
