Is there a way to find out what happened around certain date in the past? For example, by reviewing other traders' trade log on Internet, I found him "Bought AMZN Apr 50 Put @ $10.60. " on Dec. 4, 2008. How do I review this trade? I want to find out what happened around that date Dec. 4, 2008 on AMZN, where do I find such past historical news/data? Hopefully there is a software that can help with all these things! Thanks a lot!
