Many vendors provide API to connect custom made Front-Ends to their execution system/quote streams. Is there anything wise versa. So, I have a front-end which I may connect through different adaptors to different API? Thanks.
What exactly do you want? Do you want to build your own front end and target different APIs, then check out: www.trademagic.net if you want to execute through different API (brokers) via one front end then check out: www.ninjatrader.com
Actually the Trading Technologies interface will not be available until the next release. MB Trading is supported as well. The TradeMagic framework does support eSignal, DTNIQ and TrackData also. It is free to use for personal projects.
QuoteTracker has streaming and trading APIs that let you get data from any datafeed QuoteTracker supports: http://www.quotetracker.com/help/QTStreamingAPI.shtml and trade through most of the brokers QuoteTracker supports for integrated trading: http://www.quotetracker.com/help/QTTradingAPI.shtml Jerry Medved http://www.quotetracker.com
OK. I see the point. Basically let say I have an execution system (over FIX protocol) and want to have just Front-End, which will be connected to the system. The idea was to take any available FrontEnd which communicates through published API and write "converter from that API to FIX". NinjaTrader uses TradeMagic's connectivity to existing execution system, where I basically want to cut. Anything on that side? Thanks.
