After missing a lot of market movement, I've coded up a simple windows app that will notify you once the price moves +5% or -5% compared to the last notification. It pops up at the bottom right corner of the desktop, and you can also click on it for fast access to bitcoinity.org/markets (I'm not affiliated with bitcoinity).

Not much else about it, I'll flesh it out later with different exchanges support, maybe LTC. It gets the price from my server which returns the MtGox last, and if MtGox is down then the BTC-e price is returned. Currently Windows only as it makes use of .NET.

If this has helped you, please send me a tip! I'm also open to contracting work. [/plug]



MOD EDIT:
Be careful with any .exe files

Source code will be released with a small tip to my address Smiley But it's pretty simple anyway.

I'm sure you mean well, but no one in their right mind is just going to run an exe posted to this board. Or at least I hope so.

Hmm, good point. I originally tried to do it in Flash, but there was no way to bring focus to it and make it pop up from the bottom right corner.

If this only queries a website and displays popups, why not just code it as an HTML5 Windows widget?

You mean a windows gadget?

I'll look into desktop notifications, but I don't see much point in implementing them since the .net version works fine for me.

You can write it as a website using desktop notifications.
I've quickly hacked together a page using Mt. Gox... It's not beatiful code (I have virtually no JS experience, but it seems to work (haven't tested the 5% detection yet, as there hasn't been a 5% change in the last 1/2 hour...). Should be up once I have some webspace. (Only works on webkit based browsers, have only tested chromium.)

HTML5 version here:
http://teajam.co.uk/btc/btcnotifier.html

To use:
Press "Enable Notifications" before the first use.
Press "Press to start" to start.

(Has to be on webkit, haven't tested on anything but Chromium.)

It checks MtGox every 5 minutes, and updated you once the price has change by 5% or more.

I'll probably flesh it out a bit and put in a better UI later today.

//Edit: Just to make clear this notifier is entirely independent of the OPs. I just thought it would be interesting to see how hard an html5 version of it would be.

Nice tool. Although, could you have it return Bitstamp rather than BTC-e when Gox is down as Bitstamp prices are normally closer to Gox? Or perhaps allow the user to select from a list of exchanges?

That is really cool - can you do the same for other currencies, or is this only available from MTGox API?

Ah, I didn't spot that. In that case, consider my feature request aimed at you!

Nice Tool.  Wink

www.Bitcoin-Tools.de - Price Alert & Calculator [OUTDATED!]
A little tool to keep you informed or wake you up, if Mt.Gox reaches a defined price level and a calculator to convert  BTC or USD based on live Prices. It´s not working any more, because of Mt.Gox... but it was fun to code that time... keeping this link just for reminding... Thanks to everyone for donations done that time!

To avoid hijacking this thread I've created my own one with regards to the HTML5 notifier:
https://bitcointalk.org/index.php?topic=179647.0

(In summary: I'm working on support for multiple exchanges, multiple currencies & some configurability.)

I was thinking today that it would be really usefull to have something like this for my smartphone. Maybe receive a txt msg or some sort of notifcation when the price changes a certain amount.   Right now it's a bit painful to try to watch prices when you're out on the go and not sitting in front of a computer.

just use my RSS feed...  it averages multiple exchanges and gives the most  accurate price...   20,000 to 70,000 people can't be wrong.

http://feeds.feedburner.com/OuncemeQuotesFullFeed

using that at least it has failover, etc...
