[edit] Stock Exchanges

Direct access trading is a technology in which a client can trade directly with market makers or specialists at the exchange, without any brokerage mediation.

A firm which supplies this access is a direct-access brokerage firm. This trading style is primarily for daytraders or scalpers who value speed of execution and the minimisation of slippage. See direct access trading for details.

[edit] Motorcycle

In motorcycle training in the United Kingdom:

  • The Direct Access Scheme allows a person over the age of 21 to avoid the two year/25 kW restriction by taking the practical test on a machine of at least 35 kW (46.6 bhp); you may ride any size of bike if you pass this test. Before taking the practical test you must have successfully completed Compulsory Basic Training (CBT), the Motorcycle Theory Test and have the correct provisional entitlement - allowing you to ride a motorcycle as a learner - on your driving license.
