Use too much .js? Its 2014 not 1998. But cool. Hope you find a market for the site.

What market? It's non-profit.

Sure you can use a cannon to kill a fly, that's why everyone uses javascript. I prefer KISS.

Javascript is not a "cannon" lol. Its incredibly simple. With node.js you can have hundreds of concurrent users without the memory hogging / thread creating nonsense that PHP creates. By "market", I meant visitors.

Not sure of need for yet more coin charting websites. What niche are you filling with this one?

I made these charts, because i wanted to see side by side BTC and LTC prices. No other charting site can do that. Also other sites are too slow for me and they use too much javascript. I plan to add more technical analysis too, like MACD and hypothetical profit based on buy/sell signals.

Do you think that dividing okcoin volume by 3 is a good approach? See Attention in the footnote, on the frontpage: http://cosurgi.info

OK guys, the website update was finished. I added a load of new exchanges:

mtgox BTC/USD
mtgox BTC/EUR
mtgox BTC/PLN
mtgox BTC/JPY
bitstamp BTC/USD
cavirtex BTC/CAD
kraken LTC/BTC
kraken BTC/USD
kraken BTC/EUR
kraken LTC/USD
kraken LTC/EUR
okcoin BTC/CNY
okcoin LTC/CNY
bitfinex BTC/USD
bitfinex LTC/USD
bitfinex LTC/BTC

also I have moved everything a to a new domain: http://cosurgi.info

I wanted also to add bitcoin.de but they didn't respond to my email asking about access to API. So in fact they are in my database, but collecting zeros

Also I added option to toggle vertical and horizontal layout for viewing a pair exchanges, and an auto refresh option every 5 minutes. Sorry I can't do 1 minute refresh. I don't have relevant data to show every minute.

please give feeback

I added printing of "closing price" on the chart, and the last bar is always taken from 10-minute interval. So even when you look at 24-hour bars, the last bar is always the latest price. Even if current 24-hour peroid isn't finished.

Currently this last bar has width of all other bars, while it should have width of 10 minutes, but for now I will leave it at this.

This is great for a quick look at what is going on.

Where do you get the data for btcchina and fxbtc? I'm looking for last trade price for the currency pairs they offer.

I hadn't heard of Bitcurex. I'm adding to my site TradeList - http://tradeli.st

Code:

"https://data.btcchina.com/data/historydata?since="+str(last_recorded_btcchina_tid)

self.fetch(conn ,"data.fxbtc.com/api?op=query_last_trades&symbol=btc_cny&count=100") ["datas"]

Excellent. Thank you.

Hi,

I needed some charts that are actually useful, fast in the browser, and don't display unnecessary things on the website. This is official thread for these charts. I have some plans for adding more currencies and other stuff, I will edit this first post to list all current features on this simple website.
