Data types
You can only use the following basic resolutions: 1 tick, 1 minute, 1 hour, 1 day.
All other resolutions - such as 2 ticks, 10 minutes, 4 hours, 3 points, 1 second, 2 days, 1 week, 1 month, 1 year etc - are only available in the full version.
Data Server
The demo data server is not monitored as closely as the production servers. As a result, there can be gaps and interruptions in the data flow.
History
You can receive the latest 500 bars - starting with the current bar -- for all resolutions. The full version provides the data as far back as 2001.
The number of active charts
The number of charts that you can have open at the same time can be no more than 5.
In the full version, you can plot data in over 200 charts at the same time.
If your request returns the "no data" message, it means that you have made a request going beyond the limitations.
