TradeStation Network Preferences - Streaming Data Optimization

The Streaming Data Optimization tab allows you to control the amount of redundant data that is delivered to TradeStation. By enabling this feature, TradeStation will make more efficient use of your Internet bandwidth and system resources.

The daily, weekly, monthly, minute-based, volume-based and multi-tick charts and RadarScreen requests benefit from using this optimization. However, single-tick charts do not utilize the optimization feature. When data streaming is optimized, it only effects the frequency of which bars are updated of streaming real-time or delayed data. As a result, the TradeStation Data Network will suppress ticks that occur at the same price as the prior tick within the same second, but will not suppress any price changes. This will cause a reduction of redundant price updates.

 Using the optimization feature could potentially affect your EasyLanguage analysis and strategy automation, but only if your analysis depends on certain volume-based criteria that are independent of price changes, or if your analysis depends on the frequency of bar updates.

When making changes to this setting, TradeStation will notify you that you need to shut down and restart the platform for the any changes to this setting to take effect.

 Access using the menu bar File > Preferences > Network menu sequence and select the Streaming Data Optimization tab.

• High - Select this setting to only send trade ticks that has a new high or low price change within a one-second period of time. This will further suppress the number of any trade tick updates, and improves the efficiency of the application since it is only providing new price changes.
• Standard (Recommended for most users) - Select this setting to suppress any trade tick updates that occur at the same price as the prior trade tick. When this setting is chosen, TradeStation will send an update whenever the price of the last trade tick changes.
• None - Select this setting to send all trade ticks to TradeStation, even in cases in which the price of the last trade tick does not change.

 Click OK to apply changes or Cancel to exit without changes. Changes will take effect once you restart the TradeStation platform.
