Check out the new capability at http://btcprice.info/register.

You can select the threshold (4%-10%) that triggers an alert, the maximum frequency (max once an hour to max once/24hrs) and you will be notified whenever the BTC price moves more than your set threshold.

The system is designed and tested to scale to 100,000 subscribers, still delivering alerts to all 100,000 subscribers within 1 minute of the price change.

As always, btcprice.info still offers SMS and Voice (spoken announcer) quotes in English on BTC/USD prices on mtgox, in 5 countries and counting, for free.

Feedback and comments welcome, here or at info@btcprice.info.

Thanks!

If you go to the register page and change the settings, will they overwrite your previous ones for that number? That would be good, if you find you're getting alerted more than ideal.

Yes, that's exactly what it does. You can change the frequency simply by going back to the registration page, once you've activated.

I will add some documentation and more SMS commands.

Thanks for the question!

My re-registration at 10% change percent didn't seem to take. Just got a 6.2% alert.

Could you PM me with a time and timezone (of the alert, or of the re-registration), so I can find it and debug?

Thanks for the report. Certainly has been a good 48 hours for testing the volatility alert. I've had triggers in the entire range from 2-7%.

If it is bothering you while I debug you can reply "cancel" and that will stop it and delete your phone record. Then you can re-register with whatever setting you want.  I designed it so the cancel command bypasses all normal ops and directly removes all traces of the record.
