NYSE Arca, previously known as ArcaEx, an abbreviation of Archipelago Exchange, is an exchange on which both stocks and options are traded. It is owned by Intercontinental Exchange and is headquartered in Chicago.
In November 1994, Stuart Townsend and Gerald Putnam founded TerraNova Trading LLC, an electronic securities exchange, in Chicago. Its product, Archipelago, started accepting trading orders on January 20, 1997. Archipelago is one of the first ECNs and a precursor to the Archipelago Exchange (ArcaEx) that was created in 2001 to facilitate electronic stock trading on US stock exchanges.
On Monday, March 20, 2017, the Arca platform stopped functioning because of a "system issue" and the exchange was unable close trading for an undetermined number of funds. 
NYSE Arca's liquidity fee/rebate structure resembles that of other electronic communication networks. In late 2006, it was the first one to offer NASDAQ-style fees on New York Stock Exchange-listed securities, a move that was soon copied by NASDAQ and other electronic communication networks. NYSE Arca charges traders that remove liquidity from the Arca-book $3.00 per 1,000 shares. Traders that add liquidity receive a $2.00 rebate per 1,000 shares. Traders that route orders out of the NYSE Arca system are charged $1.00 per 1,000 shares for Tape A securities and $4.00 per 1,000 shares for other securities.
