Selecting a Symbol's Data Interval

The frequency at which you choose to display your price data is referred to as the data interval, whether you want a bar drawn for every 10 ticks of data or for every 1000 shares/contracts traded. TradeStation is extremely flexible; you can display your price data using a number of different intervals. Data intervals can be grouped into three categories:

  • Time-based increments - 5 minutes, 30 minutes, daily, etc.
  • Tick-based increments - 1 tick, 10 ticks, etc.
  • Volume-based increments - 100 shares/contracts, 10,000 shares/contracts, etc.
  • Point & Figure - Filter out time and insignificant changes in price, leaving a chart that only contains price movements that you believe are relevant. For more information, see Point & Figure Chart.
  1. From the menu, click Data > Edit Symbol, then click Customize. The Customize Symbol [symbol] dialog is displayed.
  2. Click the Settings tab.
