Nasdaq unveils Market Replay

Nasdaq has launched NASDAQ Market Replay, a data tool that provides NASDAQ-validated views of users’ order book at any point in time. The tool can replay the market in simulated real-time — down to the millisecond level — or at an accelerated or decelerated speed, according to the exchange. It also permits compliance officers to confirm if a trade met Regulation NMS (national market system) compliance standards and can be used by investors to ascertain whether a trade received best execution. Brokers can also send their clients a NASDAQ-validated screen shot of the moment their particular trade occurred. Professionals that want to use the service will pay $50 per month. Non-professionals might soon find it available at a lower cost or possibly free via online financial portals like Yahoo! or Google Finance, etc. Market Replay is one of the first rich Internet applications to be deployed using the Adobe AIR platform, which lets developers use existing web technologies including AJaX, Flash, Flex, and HTML to better reach a user’s desktop.
