**For real-time data services that offer all markets, you need to sign up for individual market exchanges with your data vendor for access to the markets you want. Each exchange is typically an additional fee.

Note:

Broker feeds typically do not provide much historical data. If you cannot backfill/download data for your charts, or if you see zeros for the bars in a footprint chart, this is usually the reason. Often, the amount of historical data they provide varies depending on when they re-set their servers, and you cannot generally count on them as a source of reliable historical data.

For licensed users only, we provide DTN Market Access which provides comprehensive backfill to overcome this limitation of broker data feeds. Information on DTNMA historical backfilling can be found at http://support.marketdelta.com/entries/114111.

Comprehensive, reliable historical data is generally required for most traders to accurately create meaningful charts.
