Tick Data, (www.tickdata.com), the market data division of Nexa Technologies, Inc. (www.nexatech.com), a subsidiary of Penson Worldwide, Inc. (NASDAQ: PNSN), announced today that it will now provide daily updates for futures, index and indicator data. This new service is made possible by the release of TickWrite 7, a new version of the TickWrite database management software.

• A scheduler and downloader that work together to automatically download daily updates and generate ASCII output files.
• New futures roll feature, Next Most Active, for more precise continuous futures contract roll-overs.
• Output timestamp in milliseconds when available.
• Ability to generate files of sub-minute bars.
• Enhanced file output options, including filtering by and re-ordering of headers.
• Internet delivery available for more order types and larger orders.
• Capacity to expand the scope and size of the data offering for years to come.
• Soon to follow, a completely redesigned online store that will allow clients to manage subscriptions and place orders for futures, index, indicator, and equity data.

“We are pleased to round out our daily update subscription offering with the addition of futures, index, and indicator data. Our mission has always been to provide research-ready historical intraday time series market data as conveniently as possible, so the combination of more timely data delivery and a more convenient TickWrite are in accord with that mission,” commented Neal Falkenberry, CFA-President of Tick Data. “We will continue to expand the breadth and depth of our data offering and provide more innovative technology to achieve our goal of becoming the world’s central repository of historical intraday market data.”

With more than 25 years of experience collecting, validating, cleaning, and providing historical trade and quote market data, Tick Data is considered a pioneer and leader in the field, with one of the world’s largest databases of historical intraday data.
