We understand that the speed and reliability of the data you receive directly affects your trading, so we’re committed to making sure that it’s fast and of the highest quality. By directly linking to many exchanges, we provide you with the fastest possible access to real-time, streaming data. Plus, TradeStation continuously filters all incoming ticks to improve accuracy.

The TradeStation Data Centers have direct connections to the American Stock Exchange, Archipelago, Bloomberg, Brut, Chicago Board of Trade, Chicago Mercantile Exchange, Instinet, Island, Nasdaq, New York Stock Exchange, the Options Price Reporting Authority, and for forex data.

Exchanges send data to TradeStation that sometime do not coincide with current trading activity. TradeStation tries to filter this data to remove trades of this type, so that such trades, which may be misleading, do not alter your Quotes or Hot List windows. For example, an "out of sequence" trade may come in that indicates a price higher or lower than the price at which the stock is actually trading. Because this trade appears to be "out of sequence," the time at which this trade was actually placed is probably unknown and, therefore, TradeStation removes it from the data. This trade is still valid, however, so it will still appear in the Time & Sales window and be flagged as "out of sequence."

In order to provide you with more accurate data, the TradeStation Data Network now processes real-time insertion, deletion, and correction messages sent by the exchanges. When such events occur, they are automatically applied to the data stored on our servers. This updated information is then sent to the various windows within TradeStation such as Chart Analysis, RadarScreen, Quote, Matrix, Time & Sales, etc., so that any such messages that the exchanges send can quickly take effect in TradeStation.
