It is often split into two parts – pre-trade and post-trade.  Recent regulations, such as the European Markets in Financial Instruments Directive, have required institutions to achieve best execution.  This has resulted in the emergence of a number of companies who make TCA a central offering, such as Investment Technology Group, Bloomberg, Trade Informatics, Markit, and many others. L.F.

Disability Insurance, often called DI or disability income insurance, or income protection, is a form of insurance that insures the beneficiary's earned income against the risk that a disability creates a barrier for a worker to complete the core functions of their work.  For example, the worker may suffer from an inability to maintain composure in the case of psychological disorders or an injury, illness or condition that causes physical impairment or incapacity to work.  It encompasses paid sick leave, short-term disability benefits (STD), and long-term disability benefits (LTD).  Statistics show that in the US a disabling accident occurs, on average, once every second.  In fact, nearly 18.5% of Americans are currently living with a disability, and 1 out of every 4 persons in the US workforce will suffer a disabling injury before retirement.

The Mount Street Club was a charity in Ireland for the unemployed of Dublin.  Its premises were at 81–82 Lower Mount Street, allotments beside the railway line at Sydney Parade and Merrion, and a farm in Clondalkin.  Men as members could earn ‘tallies’ which they could exchange for food, clothing, fuel or furniture on a barter or time-banking system.  It was founded in 1934 by James Hardress de Warenne Waller and Philip Somerville-Large.  Members produced or obtained food, clothing, and furniture.  Lessons in making and repairing works were given, and applied to items donated to the club.  The clubhouse had leisure facilities, a kitchen and dining-room for 100, workshops, washing facilities, and a barbershop.  The club was most successful during The Emergency of the Second World War, when it had 6,000 members.  In 1939, Seanad Éireann debated a motion that the Land Commission should donate farmland to the club to alleviate food shortages in the city.  By the 1970s its core functions had been superseded by the Department of Social Welfare.  The work of the Mount Street Club evolved over the years, and in the 1970s and 1980s it supported start-up businesses and set up training schemes for the unemployed.  In the 1990s it was involved in regenerating the Grand Canal Dock.  The club's property was sold in 2006 and it was incorporated as a charitable trust, the Mount Street Club Trust in 2007.  It continues to work on projects that give support to those suffering from the effects of unemployment in the Greater Dublin Area.

These symbols were originally devised as a mathematical notation to describe algorithms.  APL programmers often assign informal names when discussing functions and operators (for example, product for ×/) but the core functions and operators provided by the language are denoted by non-textual symbols.
