Suppose firm X is valued at 1. If it falls below 0.1, I want a stock alert to my arbitrary email. Is there some free internet site for it?

Sure, Yahoo Finance does this for FREE.

Silly, unrelated question. What tool did you use to add the arrow with drop shadow? –  Alex B Aug 24 '10 at 20:58
snagit. getit. you'll likeit. –  Michael Pryor Aug 24 '10 at 23:53
Requires 20USD to forward your mail, not really a substitute for my server at the cost of electricity, really no Free service for such simple app? –  JP. Aug 25 '10 at 12:19
@user1330 I have no idea what you are talking about. Yahoo finance is free, as well as the stock alerts. –  Michael Pryor Aug 25 '10 at 13:38
Pryor: It is non-Free. Only the basic props are free but not things like forwarding email which makes it useless to me. –  JP. Aug 27 '10 at 13:42

You can do it graphically at zignals.com and freestockcharts.com.

Widows only, apparently. –  JP. Aug 25 '10 at 12:14
I use them on my Mac. No Linux support, unfortunately. –  James Roth Aug 25 '10 at 14:09
Chrome for Mac is not really supported by Silverlight, which is used by zignals.com. See the system requirements at microsoft.com/getsilverlight/Get-Started/Install/Default.aspx –  Nate Cook Dec 10 '12 at 16:06
I use Chrome for Mac and have not had problems. –  James Roth Jan 12 '13 at 20:21

Hey guys, I found this website, it seems to do it for free, and they have many options. If let me know if you find something better than this.

If you're a customer, TD Ameritrade has a really robust alerting system.

You will have to have a yahoo account.

If you want to provide an alternative delivery email address, visit the URL above. Click "Stocks Watch", enter ticker(s) and price(s) at which you want alerts, then at the bottom select the "email" radio button. If your preferred email address is not listed, click the "Add an email address" link and follow the instructions. I don't know what their limit is, but I currently have three addresses set up -- two to non-@yahoo addresses -- and it works fine.

@hhh - I see that the same objection was raised on this answer. Let me know if the instructions above do not work for you. –  bstpierre Feb 18 '11 at 17:30
do you need to pay the 20$ to set it up? –  user1770 Feb 18 '11 at 17:37
@hhh - I have never paid a penny to yahoo. –  bstpierre Feb 18 '11 at 17:39
thank you for the info, may try it or do better myself. –  user1770 Feb 18 '11 at 17:57

I've used BigCharts (now owned by MarketWatch.com) for a while and really like them. Their tools to annotate charts are great.

Yes, there are plenty of sites that will do this for you. Yahoo, and MarketWatch are a few that come to mind first. I'm sure you could find plenty of others.
