I am looking if there are a screener refreshed in real time with predefined criteria. Reading about Yahoo Finance Market Tracker: http://screener.finance.yahoo.com/newscreener.html Screen with Real-Time Data In the description: Streaming real-time quotes, charts and stock screener What a "real time" means? 1) One possibility - when I manually screen it is returning the results valid for this moment of time. 2) Or I can set the say 20 screening parameters and it runs and screens instruments according these 20 parameters in real time? Are there somebody here in ET using it?
