Around 400 founders, sources disagree on the exact number, put up 29,870 gold coins to provide sufficient capital to establish and maintain the Prague Stock Exchange. The founders were mostly Czech merchants, including prominent sugar merchant Alois Oliva and people from the insurance and railway industries. The first stock trades took place April 17, 1871, between 11:30 a.m. and 1 p.m., in a commercial building on Na Příkopě in Prague’s New Town.
