I'm looking to build a news-based trading algo and I need a live news feed for economic data.
Are there are free sources available? I cannot find a single one.
It doesn't have to be perfect, and I'm willing to get my hands dirty and do some development but if anyone has done this before, I would like to know where you got your data and how you were able to make it "live" (that is, did you poll a service, did you scrape a page, or were you able to get a push stream set up somehow?)
As a side, I'm also interested in non-economic news feeds for a stocks strategy. Same question applies (are there any free sources of corporate news and how were you able to make it "live", if it wasnt already build for that)?
