A curb market of curbstone brokers became established on Broad Street in the mid-1800s, growing in part out of the Open Board of Brokers, previously in a building on New Street established in 1864. The Open Board was located at 16 and 18 Broad Street until 1869. After the Open Board joined the Consolidated Exchange, Open Board members specializing in unlisted stocks were left without "a roof over their heads and took to meeting casually in the course of the day in convenient lobbies in the district". In August 1865, a reporter described the curb market in front of the new exchange building on Broad Street. "There were at least a thousand people on the sidewalk and street... Buyer and seller, speculator and investor, operator and spectator, agent and principal, met face to face, upon the curb and beneath the sweltering sun, opened their mouths wide and screamed all manner of seeming nonsense at each other, while their hats tipped far toward the small of their backs, their eyes strained fiercely and their arms waved wildly above their heads, from which rolled rivers of profuse perspiration." In 1877, a new organization the New-York Open Board of Stock Brokers commissioned the same building at 16 and 18 Broad Street used by the old Open Board.
