Problem:
GT is very dependent on external data providers for historical and Indraday price data. This dependency should be reduced and GT instances should optionally share their price data with each other. Of course, the original price data still comes from paid or unpaid external data providers.

Solution:
Operators of GT instances can optionally offer their server as an exchange platform of intraday price data. When updating the price data of a watchlist, one or more of these GT instances will be requested first. This may be followed by a request to the external data providers. Finally, the previously selected GT instances are supplied with the Indraday price data.
