Occupy Wall Street protesters marched on the New York Stock Exchange Thursday morning to stop traders from reaching the building. Despite their demonstration, trading began as usual at 9:30 a.m. EST. As of 10:30, 50 Occupiers had already been arrested, according to the New York Times.

The face-off between protesters and police is not unusual for the 2-month old movement. NYPD cleared Zuccotti Park Tuesday, ostensibly to clean the grounds. The eviction seemed to reenergize protesters, who vowed to regroup and "come back every day."

The New York Times reported from the scene Thursday morning:

At one point, protesters surrounded and halted police vehicles on Exchange Place and at several points called out to block access points into that part of the financial district. On Broad Street, police officers moved metal barricades to allow a police vehicle through. Some protesters shouted “come on” and began moving quickly toward the opening. Officers shouted “nobody can come in here,” then closed the barricades again, keeping the crowd from marching toward the stock exchange.

After two men wearing suits were allowed to pass through a police barricade at the corner of Pine and William Streets, one protester said, “There’s a dress code for this intersection?”

New York blog Gothamist reported some civility between police and demonstrators:

Update 10:15 a.m.: At Beaver and William Street, cops have just warned protesters via bullhorn that they will arrest anyone remaining in the street. Protesters have locked arms and the cops are now making arrests.

While there have been some violent incidences, Robbins says that it appears cops are trying to be as restrained as humanly possible, even stopping more aggressive colleagues (apparently a cop lunged at protesters, but another cop yanked him back by the collar). Robbins adds that before the police warning about arrests, a police officer in a suit asked protesters if they were staying—when protesters said yes, he made a call on his cell and said, "They're not going to move back," seemingly getting feedback from even higher-ups about next steps.

Touted by some as a Day of Action, Occupy encampments all over the country have planned protests for Thursday, though some have been more clear and successful than others. Occupy Philly announced a rally would take place this afternoon at Dilworth Plaza after officials said Wednesday police would refrain from taking action for 48 hours. They were then told, however, to clear out instead.

Occupy Dallas was actively cleared by police early this morning; it's unclear whether demonstrators planned to participate in the nationwide rallies.

In California, Occupy Cal at Berkeley was swept by UC Police around 3:45 a.m. from the campus' Sproul Plaza according to the San Jose Mercury News.

Occupiers have started their planned march on downtown Los Angeles. Most streets in the city's financial district have been shut down by the movement. Reports placed the demonstration in the Bank of America plaza at 8:10 a.m., en route to Figueroa.
