TradeStation’s third party data capability
You may need to use data for a symbol that is not currently available through TradeStation. Assuming that you can find an outside source for the data and are able to download and format it appropriately you can use the data with TradeStation’s third party data tool. Although the data will not be real time it would allow backtesting and technical analysis.
The third party data tool also allows you to utilize TradeStation data that you have saved. A possible use for this is as follows: tick data is only available for the previous six months, however if you had saved the previous six month’s worth of data this could be concatenated with the current data to create a data file which contains 12 months of tick data that could then (at least in theory) be utilized using the third party data tool.
Once a symbol has been created using the third party tool it can be re-used.
The two videos below give two examples of how to use the third party tool.
