Answer 2

Explanation:

trading jacket is a blazer garment worn by a broker who executes trades by open outcry in and around the trading pits of various financial exchanges. Throughout the twentieth century, trading jackets were simply white. Following counterculture of the 1960s, they became brightly colored and distinctive to assist in the identification of specific traders or the exchange members for whom they work. In the United States, American flags became a common accoutrement following the September 11 attacks.[1] Today, trading jackets are mostly anachronistic as open outcry exchanges have been displaced by electronic trading platforms. Chicago-based PECO Inc has been the leading supplier of trading jackets since 1919.[1]
