Hi, Jcl,
I think it would be a great idea to integrate Zorro with SierraChart (SC).
SC is a very lightweight,fast and well engineered application, has very robust integration to nearly all key brokers and datafeeds (including their own) and can also work as a data/oms server - a single point gateway to all of them.
http://www.sierrachart.com/index.php?page=doc/SupportedDataAndTradingServices.phphttp://www.sierrachart.com/index.php?page=doc/Contents.php#ExternalInterfacesThis can be easily achieved via SC's DTC protocol - an improvement on FIX. It is very well documented and well supported by SC.
http://www.dtcprotocol.org/#DTCProjectshttps://github.com/DTC-protocol/DTCCombining all the great scripting and analytical capabilities of Zorro with robust access to data and brokers would be a superb combination, and would likely multiply Zorro's user base 10+x.
