Indeed, some exchanges truncate their order book (BTC-E for example).
But the bid/ask sums may not be that meaningless, their scope is just limited to the provided range of orders.
Eventually, accuracy of this metric depends on the distribution of orders in the book.
Perhaps one needs some indicator of order depth that is less sensitive to truncation? E.g., weighted total sum of order size (BTC), where the weight decays exponentially with the difference between order price and current price? With such a formula, one could compute relatively tight upper and lower bounds for the indicator, even from a truncated order book. Its a good idea and one that I've thought of before, its not something I have the time or maybe even the skills for but Im sure there are people who could do this, in fact Im sure some probably already have. Interesting idea, I'll try to look around to see if something like that already exists ; could be a good addition for Coinorama  |

PS. By the way, it is not just the Chinese exchanges that truncate the reported order books. One could clearly see the truncation in some of the @Chartbuddy plots of MtGOX, when that exchange was alive. The API specified by bitcoincharts is described here. Presumably the other chart sites depend on this same API. I cannot see how the exchange could report their total bid/as sum through that API except by reporting the entire detailed order book. In fact I see no reliable way to tell whether the book was truncated or not. If the book is truncated, the bid/ask sums computed from it are wrong and mostly meaningless. Indeed, some exchanges truncate their order book (BTC-E for example). But the bid/ask sums may not be that meaningless, their scope is just limited to the provided range of orders. Eventually, accuracy of this metric depends on the distribution of orders in the book. |

Ça semble fonctionner. Je croyais qu'il fallait inscrire une clef publique et non un numero de block.
La recherche d'adresse doit fonctionner aussi (tu peux saisir une adresse, un numéro/hash de bloc ou bien un ID de transaction). Peux-tu essayer avec l'adresse des donations : 15At8pPhcoQySMmytGiANYLxFzr3vcKFRF ? Ça fonctionne de mon coté... :/ |

This is great. I'm having trouble expanding the nodes also. The menu doesn't appear. (Macintosh OS X 10.9.2, Chrome 33.0.1750.152, no errors in the console). I'm putting together something similar myself for a service called QuantaBytes ( http://www.quantabytes.com) but I'm not as far as you. Thanks When you move your mouse over a node, is it highlighted ? I'll try to debug the site in chrome, I use firefox on my development box. Thumbs up for quanta bytes ! Yes, the node is the highlighted. Hey, I pushed a little update which could hopefully fix this issue. Could you give a try ? Cheers ! (just in case, reload the page once in order to flush your browser's cache) |

Ma cible c'est le lobby bitcoin-central , et les ennemis de mon ennemi sont mes amis .
Vive chronocoin, vive beegcoin, vive coinorama !
Euh... Si tu fais référence à coinorama.net, c'est très gentil de lui souhaiter longue vie. Je suis par contre un peu embarrassé par le contexte de cet encouragement, je me dois de préciser que je n'ai aucun ennemi. |

et moi ça me dit que le service est down...
À quel moment ? Lorsque tu fais une recherche ? Oui Mince alors.... Et si tu cliques sur un numéro de bloc, ça le fait aussi ? Le ticker à droite fonctionne ? |

Indeed, it seems like arbor is overloaded, and in addition, drawing the graph is quite expensive because of the labels... I'll try to find some workaround, thanks for the feedback ! |

Quand j'entre mon addresse "1LuckyG4tMMZf64j6ea7JhCz7sDpk6vdcS", le montant dans le champ "Received:" n'est pas correct. L'erreur est grosso modo de 1400 BTC Ah c'est bizarre  La balance semble correct toutefois et le nombre de transactions aussi ... Peut-être un bug dans l'accumulation, je vais mener ma ptite enquête. Merci pour le bug report. et moi ça me dit que le service est down...
À quel moment ? Lorsque tu fais une recherche ? De la balle. J'avais oublié que c'était francophone  Rajouté il y a peu dans ma barre des favoris et pas perdu dans un dossier monsieur, non non ! Il a droit à sa propre icône vu que c'est un peu le seul site qui me permet de check l'historique du bid&ask sum en graph ! Tip is on the way, c'est aussi rare que de rajouter une icone well done  Cool, merci beaucoup ! |

Bonjour à tous, Ces derniers temps, j'ai un peu bricolé avec arbor.js [ http://arborjs.org/ ], une bibliothèque de visualisation de graphes. J'en ai tiré une nouvelle fonctionnalité pour Coinorama, il est désormais possible d'afficher un graphe de transactions et d'adresses : http://www.coinorama.net/blockchain Ouvrez n'importe quelle adresse, block ou transactions ; vous verrez un bouton permettant d'ouvrir la fenêtre de graphe. Le bouton sert ensuite à ajouter/retirer d'autres transactions. C'est tout neuf, donc pas forcément exempt de bugs (apparement, le sous-menu clique-droit ne s'affiche pas correctement sous Chrome) N'hésitez pas à partager vos impressions et les problèmes rencontrés |

just played around with it - super cool use of arbor.
how do you expand inputs or outputs to see deeper nodes?
Click right, then open details window, you'll be able to spawn new nodes from there. |

Hey, I am currently playing with arbor.js, a neat graph visualization library. I just added to Coinorama a new feature based on it. You're now able to graph transactions and addresses : http://www.coinorama.net/blockchainOpen any address, block or transaction and you'll see a button to open the graph window. If some of you are interested in blockchain forensics, have a look and tell me what you think :-) Cheers ! |

J'aime ! Si tu développai un système d'alerte ( avec un cron par exemple ) ce serait super Ex : dès que le bitcoin atteint 390€, tu génére un mail à ceux qui l'ont voulu Merci ! Je bosse actuellement sur la partie exploration de blockchain, peut-être qu'un système d'alertes viendra par la suite |

Hi,
Quick status update after a small upgrade :
* Bitfinex and Huobi exchanges are now available
* Disabled USD conversion when showing exchanges using the same currency
* Minor reliability fix for slow connections
In the coming weeks, I'll probably try to focus on the blockchain browser.
Cheers !

Looks great! Really love the clean new design. Not sure yet what the additional functions (e.g. "network activity tracking") are useful for, but I'll find out Tip on the way, by the way. Thank you very much for your support ! The network view is quite minimal at the moment, I hope to improve it soon In the mean time, I plan to push a set of minor fixes next week-end. Cheers ! |

Bonjour à tous,
Un petit UP pour annoncer la mise en ligne de la nouvelle version.
Le site a été pas mal enrichi avec l'ajout d'un explorateur de blockchain et de quelques graphes sur l'activité du réseau.
Je compte sur vous pour faire la chasse aux quelques bugs qui ont pu m'échapper.
À plus !
