btc-alert.com: get gTalk notifications for prices on mtgox

[rammerhammer]

Hey guys, I've just finished putting together a site that will send you notifications over gTalk when the markets cross a price you input. Currently only works with Mt. Gox and USD. You can check it out at www.btc-alert.com and read the latest news at blog.btc-alert.com. I plan on adding other exchanges and currencies in the future, as well as an iPhone app with push notifications.

Any chance to get HTTP(S) POST notifications?

UPD: What about connecting by TCP to bitcoincentral live feed at bitcoincharts.com:27007 and getting all exchanges supported at once and in real time?

What do you mean by POST notifications? Also yes I do plan on using the bitcoincharts feed later on and allowing the user to pick their exchange/currency. Right now, though, they ask that you restrict updates to once every 15min so I'm considering using the individual exchanges' APIs instead.

The feed is realtime. The 15 mins restriction applies only to non-realtime bitcoincharts API. The feed support must be much easier implement than a dozen of individual APIs unless you use a lame technology.

By POST notifications I mean the following service:

1) A user enters an HTTP or HTTPS URL on your site and configures alert conditions
2) When the price changes you perform a request to the given URL and pass extra parameters
3) User's web server (e.g. a trade bot) receives the alert
4) PROFIT!!!

Hrm.. interesting. I think I'll add it to the list. iPhone app next though.

Oh I see what you were saying before. There is a realtime server they have over telnet. I might use this, there are some things I need to consider though. Right now the server I have is not realtime and has a delay. Processing these things in realtime I may still need to have a delay just because of server load limitations depending on how big the databases get.
