(Adds Deutsche Boerse comment in paragraph 4)
FRANKFURT Oct 27 (Reuters) - Protesters entered the Frankfurt Stock Exchange on Monday, shouting slogans and waving banners denouncing financial markets.
The protesters from the anti-establishment Attac movement, who hung a banner over the stock exchange's big board displaying a graph of Germany's benchmark DAX index, were inside for a few minutes, a Reuters photographer on the scene said.
He said there were about 15 protesters and that three security guards escorted them from the building in the heart of Frankfurt's banking district.
Stock exchange operator Deutsche Boerse (DB1Gn.DE) said nobody had been injured and that trading had not been halted.
The group had registered as visitors and launched the action from the visitors' gallery, Deutsche Boerse said in a statement, adding that security measures for visitors would be tightened.
"Disarm the financial markets," read one Attac banner. "Put people and the environment above shareholder value."
A trader on the stock exchange floor said the protesters had time to throw around "thousands" of leaflets.
"The financial crisis is a symptom of a deeper rooted sickness: of an economic system that even when it is performing correctly subordinates all social goals to shareholder value and the profits of investors at the expense of jobs, social equality and environmental protection. It has to end. The casino should be closed," Attac said in a statement about the protest in which it said 25 activists had taken part.
Attac recently staged a protest outside the Frankfurt stock exchange demanding an end to "casino" capitalism. (Additional reporting by Tyler Sitte and Peter Starck) (Reporting by Kai Pfaffenbach; writing by Peter Starck)
