This is an awesome site -- I love how it looks! Any chance of releasing clones of this for other coins as well (Alt/BTC)?
Thanks ! Yeah, I plan to add Litecoin support. Probably, by the end of this summer  |

Hi all, The service has just been upgraded  Many things packed in this new version : - Added BTC-e exchange (I used to have some troubles with their API, turned out I was using it wrong
 ) ; - Added a setting for merging rate and Bids/Asks ratio in a single chart ;
- Bandwidth reduction for the order book ;
- Decreased refresh delay to 4 seconds (I am slowly decreasing it as long as the server can handle it) ;
- Improved tick display for large values, now adding a K or M suffix for 1000s and 1000000s) ;
- Reduced margins of legends (they still hide the data sometimes, I'll try to address that soon).
As usual, there are also a couple of changes behind the scene. This time, I focused on reliability and stability of the data engine Regards |

Hi, Would it be possible to add http://www.coinorama.net to the list ? Currently, I have a fair amount of unique visitors each day (more than 400) and a minimum of 20 people connected continuously Cheers ! edited: fixed URL |

Thanks When I restart my data engine, the requests are temporarily rejected (I haven't found a better plan yet). Have you seen a message on the webpage telling you an error occured and that the site was probably being upgraded ? |

Hi, I just upgraded some components of the website, please hit Ctrl+R or F5. There are two changes for the users : - 2-weeks view has been replaced with a 1-month view
- automatic refresh delay has been decreased from 6 to 5 seconds
Other changes are behind the scenes and should slightly improve your experience Expect another update this week-end, comments and ideas are welcome ! |

"What BTC Global has done is set up a pre-IPO auction. They are selling 6% of their equity, which is something they can only do because they’re in Uruguay."
Who writes this gibberish? What, exactly, is the pre-IPO equity of a company which is raising capital by selling its pre-IPO equity? If you can't understand the previous sentence, I've done my job.
Exactly ! I tried to read the article twice, but still couldn't figure out what the writer was so excited about... Has anyone understood what Massive Parallel Licensing is ? |

OP, are you still confident about your prediction ?
17k BTCs needed to reach 120 $ on MtGox...

Hi,
I just added Kraken to the exchanges available.
Greetings !

All right, upgraded version is up and running ! Amon others, new features include : - Candlesticks support for USD/BTC rate ;
- Preferences window ;
- Enabling/Disabling the display of moving averages.
Please, if you had the website running in the background, reload the page (possibly twice if your browser has a conservative cache policy). Greetings to oda.krell for his comments and ideas. Hopefully, I'll be able to add a few other stuffs before the week-end. |

Given the current activity on the exchanges (and on the website), I am postponing the upgrade to tomorrow. Besides candlesticks, I packed some other little improvements. I'll let you know when it's up  |
|
|

It seems to be working now but no trading on Clark Moody, Bitcoinwisdom or Bitcoinity
Yeah, the MtGox API has been unavailable for five minutes. The log of my MtGox listener for Coinorama shows many "Connection Closed" errors. |

Couldn't you simply place the legend outside the box? Or make the font smaller, so that it takes up less space? On my screen, the legend covers almost half-way the horizontal dimension of the box. For comparison, in a single, bigger box like on clarkmoody it covers, maybe 5%, 10% of the box, on my screen.
Yeah, great idea ! I'll try to play with a couple of parameters and improve that. Heh, I was wondering how popular your service was so far. I'll mention it a few more times on the speculation forum.
I don't have much statistics regarding the web-server. I only record the number of requests my data engine serves : right now it's about 150 per minute ; that means there are about 15 people with the page opened. The engine can support much more, bandwidth will probably be a bottleneck first if the number of users explodes. I am currently working on candlesticks support : it should be online tomorrow ! (the upgrade may break current data connections, you'll have to reload the page to get it back).
I am done with candlesticks, I'll enable it in a couple of hours. It's not perfect, but usable. |

Fantastic tool! Rarely happens that a new one besides clarkmoody, bitcoincharts and one or two others enters my daily bitcoin routine, but your site did immediately.
Can I a make a few suggestions? Some things that don't work 100% yet, at least for me...
1) button to disable moving averages. not always needed, and they tend to cover the price graph which i tend to look at more often.
2) labels in window 1 (rate USD) and window 2 (bids/asks) tend to cover up the price. Maybe it's just on my small-ish screen, but if the price graph is in the upper third of the screen, the labels cover large parts of it.
3) as you gather more data (or if you include historical data that you can download, AFAIK), could you implement the option to go back further than 2 weeks?
4) perhaps the biggest selling point of your website for me is that it finally includes the option to look at the order books of the 2 biggest exchanges. but:
4.1) any chance you can include the 3rd largest, btce, as well? together they acount for 80? 90? percent of the entire USD market, so seeing the order books those 3 exchanges would really mean something.
4.2) even if 4.1 is not an option right now, could you perhaps include the option to "aggregate", under what is now the "both option". Ideally, if you would have 3 exchanges (or even for the 2 you have now), the "both" option shows the separate graph of the exchanges. However, I would love to see a checkbox that adds up the data of all exchanges. Sure, it would be an average that is not entirely accurate for any particular exchange, but to gauge the market as a whole, I would find it extremely useful.
Wow, thanks for this thorough feedback ! It's much appreciated and motivating 1) Sure, I'll add a setting for that as soon as I have figured out how to organize settings (creating a dedicated panel, adding icons, etc.) 2) That's not easy to fix properly : if I reduce the range of the Y-axis, lines will be less precise ; on the other hand, I have no way to detect overlapping of lines with the legend 3) As soon as I have 1-month history for MtGox, I'll enable it ; downloading previous data can be done, but I am afraid I won't have all the data required to compute all charts 4.1) I have BTC-e support ready, BUT I have a lot of troubles fetching their data regularly (their servers may be overloaded). Besides, I am afraid that adding lines to the order book charts makes them unreadable. 4.2) Indeed, cumulating (and averaging when relevant) the data of all exchanges can be done, I'll add that similarly to the 1st item. Yesterday, I saw a very nice increase of the requests to my data engine (x5 in a day), that's really cool I also received a second donation ! My objective is to get the hosting funded by the users (thus I wish I'll receive about 0.8 BTC per month). In addition to the suggestions listed above, I also have a couple of items in my todo-list, I'll do my best to balance my efforts between all of them. I am currently working on candlesticks support : it should be online tomorrow ! (the upgrade may break current data connections, you'll have to reload the page to get it back). |

The discussion seems to have been quite interesting, that summary sounds nice Has anyone found a video ? |

Thanks for the info, a bit clearer to me now. Any reason why Bitstamp is way below 1? (I think it was around .4 or so) on the bid/ask ratio chart). Also, have you played with combining the ratio chart with any other indicators? I have a feeling there might be something there.  But, just a feeling... Well, there aren't that much bid orders on Bitstamp, thus the Bids/Asks ratio is low. Regarding that low volume of bid orders, I am afraid I can't provide any explanation, but the Speculation guys may have some insights I would be glad to add other indicators, based on the ratio chart or any other number stored by Coinorama. If you have a precise request (description + calculation formula), I'll give it a try. |

Hi,
What you describe is expected as the "normalized" Bids/Asks ratio depends on the rate.
So, if the rate goes up, the "normalized" ratio goes down, and vice-versa.
Example :
Rate is 120 USD/BTC
Bids/Asks ratio is 150 USD/BTC (meaning : the order book contains 150 USD of bids for each BTC of asks)
Then, the normalized Bids/Asks ratio is : 150/120 = 1.25 (meaning: the bids/asks ratio is greater than the rate)
If the rate goes down, the normalized ratio goes up because of the widening gap between Bids/Asks ratio and rate.
If the rate goes up, the normalized ratio goes down because of the shrinking gap between Bids/Asks ratio and rate.
If the rate is stable and the Bids/Asks ratio changes, that means the order book has been modified.
Looking at the normalized ratio is not easy because you have to track rate movements as well.
However, it is a shortcut to compare the order book to the rate.

It says it is an ask/bid ratio (not bid/ask ratio), so I'm confused a bit as to what I am looking for. Can you walk me through an example, please? Damn, sorry about that. The label of the chart was not correct ! I just fixed it and added a checkbox so that you can disable normalization of the total Bids/Asks ratio. So now, you have : bids/asks ratio = (sum bids / sum asks) normalized bids/asks ratio = (sum bids / sum asks) / rate Please reload the page until you see the checkbox ps: sorry guys for those off-topic messages, Coinorama.net has its own thread here : http://bitcointalk.org/index.php?topic=216861.0 |

Anyone know the bid ask on the other exchanges, or maybe an overall average?
Hi, I am showing the bid ask sum for BTC-e on http://www.coinorama.net. It's the second chart on the left (well actually, I divide the bid ask sum by the current rate so that if the ratio is > 1, it means that the bids sum is higher than asks sum). Hey there, thanks for the link. Bookmarked and following, and looking for that > 1 ratio Any more info on the charts or things to keep an eye out on? I'm still in the learning phase. Appreciated, IAS edit - can you clarify what you do, as I see it already is a ratio (2nd chart on left) Thanks for following The second chart on the left is : normalized_ratio = (sum bids / sum asks) / current_rate What you were looking for initially was : ratio = (sum bids / sum asks) Switching from the regular ratio to the normalized one is pretty straightforward, I should add an option to do that ! |
