Hi
I like your extension to Chrome, thank you! However, I have some issues. The size of digits is so big, that numbers (with 8 decimals long) are not fitting the size of their fields.

Hi,
graph is not working any more. I tried to build it invoking directly the url that builds it, but without any success. Is it possible to fix it?
Thanks for the great tool Smiley

Hi! I love this extension, but I found out that bitstamp value does not update correctly.. for instance, it's at 808.4 now, but it shows as 767 on the ticker..

Fixed a couple of failing altcoins today, removed mincoin cause I can't find a proper place to get its exchange rate from and added Singapore dollar after a user request. The new version should be up shortly. Please tell me if I'm missing some fancy new altcoin that you'd like to be added. :-)

(@Felix: not sure how you want me to add hitbtc. It's not a different currency so I don't know what's there to add. I could add it to the BTC average price that I'm calculating but it's not that high volume yet I think, is it?)

Tritonio, Hello! You've made an incredible extension!

My name is Felix Griffin and I represent TeddMarketing agency.
My client is a bitcoin exchange [urhttps://hitbtc.com/l]hitbtc[/url].

Hitbtc was built on top of modern technologies to provide fast, secure and reliable service.

Customers appreciate fast order execution, convenient ways to add deposit and withdraw and competitive client service. Newcomers like intuitive user-friendly interface and easy-to-start platform.

According to bitcoincharts statistics, hitbtc is on 2nd place in EUR and 6th in USD trading volume between all exchanges.

I would like hitbtc to be listed in your extension.

You can find api documentation to add hitbtc to your site here. If you'll have more questions please feel free to ask me personally or hitbtc support.

New features in v3.1.0: The custom graph gets tied to the conversion result when you click on some other currency in the converter! If you hover on Biticker's icon in your browser, you can now see the current difficulty too. Also some other minor changes.

Like it ! ,,,

From the guy that brought you BitcoinPortable.au3 Grin

Nice to see you're still active.

Hello Transisto. Nice to see people sticking to my stuff. :-)

when the icon is red that means bitcoin is down right?

No the icon is always the same. I recently changed the icon to be reddish/lava-ish to distinguish it from the classic yellow/gold icon that many extensions use.
What actually shows the direction of the last price change is the background color of the ticker (the badge) itself. Red for falling, green for rising.

Also you can always switch back to the old yellow icon if you want. Go to the option's page, somewhere near the bottom.

very cool !!!


can you add the option to show graph as candlesticks? in 1/ 4h / 1day

then its perfect for me Smiley

I've got the candlesticks in mind but I need to change some other things first in the graphs. For example if my server crashes for 24 hours, the graphs will PAUSE for 24 hours. And when it resumes generating graph points it will resume from the point it stopped! So the old parts will be "out of sync" sort  of. They will look like they were 30 hours ago (for example) but in reality those points will be 30+24=54 hours ago. I first need to fix this and then I'll probably do the candlesticks. Currently it's just to take a quick glance at what the price has been.

Do not forget that you can always use a custom graph URL!!! So you can go to bitcoincharts, generate your own custom chart and copy the url to biticker! (Just try to add a parameter to make the graph width 700px if possible, else it will be scaled.)

Version 3.0.0 is out.

* The long promised graphs are here. They are far from perfect so give them a try and tell me what you think.
* New icon. The common bitcoin icon was... common, so I edited it a little.
* In the options page, you dont' have to click exactly on the checkbox of currencies and the option boxes, you can now also click around them in their cell and it will still work. Should make currency selection easier.

New version (2.2) coming up in a few minutes:

  • Option sound effects for notifications.
  • Bug fixes mostly around the background color of the ticker.

PS: easily customizable graphs will have to wait some more time before I figure out an efficient way to make them.

Quite a few new features:

  • You can now select ANY combination of currencies for the ticker (like LTC/EUR, EUR/DVC, EUR/USD etc).
  • BTC ticker symbol is now the average BTC price, based on multiple exchanges.
  • New GOX ticker symbol is the current Mt Gox price.
  • Notifications for price of limits will not show a second time unless the price goes back within limits first.

There might also be new bugs, Cheesy so if you see any don't forget to tell me about it!

Question: When price exceeds the limits and a desktop notification is shown should I change the limits? Specifically:

1. If you set a high limit at 31 and the current price climbs to 31.2, should I increase the high price to 31.2?
2. Should I leave the limits as they are but instead never show a new notification unless the price first falls back in the limits?
3. Maybe it would make sense to widen the limits to include the *average* ONLY if the average also goes off limits? (I think this would be confusing for the users that don't know this detail though so I'd rather avoid this solution)

Currently it will just keep poping up the notification every 5 minutes as long as you don't change the limits manually.


I vote for 2. it is the most logical.

You should use the average price from multiple exchanges, not just mt. Gox.

I'll make it so that the average price takes Bitstamp into account too. The current price will still be coming from Mt Gox though since that's the one that changes the fastest.

Sounds great.

It's done, in cased you missed the server notification.

And in case anyone is interested in the details here is how I calculate the average currently:

This runs every minute: (but doesn't necessarily query Bitstamp and MtGox every minute)

BitstampAverage=BitstampAverage*0.9872+CurrentBitstamp*(1-0.9872)
BitcoinAverage=0.6*MtGoxAverage+0.4*BitstampAverage

(MtGoxAverage is taken from https://mtgox.com/code/ticker.php which is API v0 so it's not the same as the one shown on their main page)
0.9872 is chosen so that BitstampAverage is 99% affected by the prices in the last ~6 hours, 90% affected by Bitstamp prices in the last ~3 hours and 50% by the last ~54 minutes.
I wish I knew what kind of average is the Mt Gox average in API v0 so that I could use the same for Bitstamp...

1.8.1 is out.

Changes:

Desktop notifications for when the BTC prices exceeds some user defined limits.
Now the current Bitcoin price is used instead of the average because the average looks like it is lagging (it is not). You can still select to use the average from the options page.
Revamped the options page a bit.
Server messages will pop up announcing new features, problems or whatever. You can turn those off from the options page.
Changed the tooltip of the Biticker button to show BOTH average and current rate.
Put a big icon that opens the option page on the top left corner of the currency converter in case someone doesn't know how to open option pages in Chrome.
Fixed SLL rate.

Thanks to everyone for the feedback!

It now remembers the last value your wrote and whenever you reopen the converter window it will be loaded at the proper place and all conversions will be updated. So for example you might want to input "1" into XAU (Gold ounces) to see the current gold price immediatelly whenever you open the window.

Also as I said in my previous edit, currencies are color coded. Yellow for precious metals, green for fiat, blue for cryptocurrencies and light green for linden dollars which is fiat but maybe even worse. ;-)

Added Namecoin and Litecoin. Also centralized and mirrored all the currency data on my servers so that permissions asked are even fewer and all exchange rates can now be fetched in a single request. I also mirror the two default graphs on my server to avoid straining bitcoincharts since the Biticker's userbase is growing.

Next version will properly utilize the new Chrome API so that the whole thing might use less RAM and CPU (although neither has ever been in issue IMO). In other words I will remove the background page of the extension and replace it with alarms or what you have (I don't remember how Chrome calls them).

Are there any other weird/virtual/crypto currencies that you would like to be added? Or normal currencies of course.

EDIT: 1.6.0 is out which adds color codes to currencies and a few more currencies.

Added INR (Indian rupee). Please suggest more currencies to add if I am missing yours.

Openexchangerates is unfortunatelly no longer "open", it became a paid service. I switched to another source (that I host on my own).

Oh I also enbled a new feature in Chrome Market and you can leave feedback or ask questions from the extension's page directly. (there is "give feedback" link or something like that)

Done. I added more currencies and there is an option page which lets you deselect unneeded currencies, pick the currency that will be displayed in the ticker and also customize the URL of the graph. :-D I've also refactored the code and it's trivial to add more currencies. I'll probably let users pick their own currencies by code in a later version. We'll see...
