The ticker has been slightly improved, as well as the ticker API.
Besides, coinfloorGBP, anxEUR and anxGBP are now listed.

Cheers !

Hello,

This week changelog looks like this :
 * Added ADX, TSI and ATR charts
 * Added 3h, 12h, 3d, 2w, 3m view periods
 * Added Min/Avg/Max Price chart [experimental]
 * Improved x-axis ticks formatting
 * Added log display mode to price, volume and nb. trades chart
 * Smoothed RSI and Bids/Asks ratio in multi mode

Feedbacks on the Min/Avg/Max price are welcome : it's a last minute hack.

Have a nice week !

Hi Jorge, thanks for taking some time off the Wall observer to comment here Wink

However, I was confused for a while because the color key in some plots was incomplete (In the Order Book, for example, there was no key for the blue line.)   Eventually it occurred to me that the key may be clipped off, and indeed the missing patches showed up one I widened the window to the full width of my display (1680 px).

Since some people will not have that many pixels, why not display the color key only once, vertically, on the right column?  (The colors had better be the same for all plots, anyway, to make the charts easier to read.)  It would also leave more space for the plots themselves.
Yeah, I am trying to figure out something better ; but I've been unsuccessful so far.
I am not sure about moving the key out of each chart box, this might not be visually appealing, and it would prevent individual screenshots...

You may consider also allowing the user to select which exchanges are to be plotted (if there is not such a feature already), perhaps up to a certain maximum.  I would rather look at OKCoin or Huobi rather than BTC-China.
That's already possible ! You may select up to five exchanges ; unselect one of the five to be able to select another one.

Three features that I miss in BitcoinWisdom and you may want to add to beat the competition: volume in log scale (Eg. did Huobi grow exponentially since it opened?), a trade-by trade plot, like this and the ability to plot any past epoch with 1 minute resolution (which requires entering the start date-time with keyboard -- scrolling would be too cumbersome).  Bitcoincharts has this.
OK for volume in log scale, I'll try to add it this week-end.
Not OK for trade-by-trade plot, this won't be easy to implement given the current data model.
Why not for epoch selection, it's actually available in the back-end; I still have to design a nice UI for that and patch a few things.

Another thing that may become very popular is a merged order book depth plot.  Namely, merge the order books from all exchanges (with proper shifts and conversion factors) and then compute the cumulative sums.  I believe this makes sense, since arbitrage effectively merges all exchanges into a single market -- so that, for example, a huge bid wall in China will block a price drop at Bitstamp.
Ah yes, it has indeed been requested by others ; might be available in two weeks.

Thanks again for the thorough feedback, have a nice week-end !

Some people will want to see more than 1 year.

Any chance you could make the MA on the first chart optional? It's sometimes preferable to see price alone, without any overlaid indicators.

Yes, I am adding a MA toggle to each relevant chart.
The settings window should be gone by the end of the week.

By the way, I just fixed touch events on tablets and phones... Hurray !

Looks very good to me. I like it.

But it _does_ look like sthg broke.

How to reproduce:

Single exchange, Bitstamp.

Settings: disable small views. disable moving averages.

Change time scale, or reload page: bid/ask doesn't load anymore.

Hey Oda,
Thanks for the feedback. Indeed, the "disable moving averages" setting breaks the bids/asks ratio chart.
I fixed it in my development tree yesterday, but forgot to push the fix on the server. It's now fixed.
Greetings Smiley

ps: coming this week-end -> MACD, code optimization and various minor fixes & improvements

Hi,

Here comes an update of the markets user interface.
This is a major rewrite which enables to select which charts you want to display. Hopefully, I didn't break anything.
Additional changes are too many to be listed completely, but I have to mention : legends moved out of charts, new charts (nb. of trades and average trade size) and EMAs added to single 'mode'.

Don't forget to reload the page twice in order to flush your browser's cache.

Cheers !

Awesome! I was initially confused and then very happy when I went on my phone at work-er, break - and could see which was bid/ask without squinting Smiley

Hi everybody,

I just pushed a new version of the website, here is what's new :

  • mining pools share is now tracked, thanks to mempool.info
  • new USD exchange : lakebtc
  • new CNY exchange : OkCoin
  • new LTC exchanges : btce and kraken
  • added an option to select the colors theme (requested by derpinheimer)
  • bitcoin-central renamed to paymium
  • single exchange mode now defaults to candlesticks display


LTC exchanges display is experimental, the idea is to support altcoins just like any other currency.
There were many changes behind the scenes as well, paving the way for forthcoming features.

Please let me know if you find any bug or have any suggestion !

Thank you for your support Smiley

I love this site, but why the awful color scheme change awhile back? Red and Green is much better than Yellow and Darker Yellow. Its not enough contrast.

Any way to make it a setting? Colorful vs Bland color scheme?

Hey, thanks for the feedback !
I'll try to add something to enable different color schemes ; that shouldn't be much work, but I have plenty other stuff cooking  Wink

Multiple exchanges mode now allows the display of up to five exchanges (this limit will be progressively increased).

Hava a nice week !

I would like hitbtc to be listed on your website.

thanks for not adding hitandrunbtc.com Grin

Hello,
The addition of hitbtc to Coinorama is ready.
It hasn't been enabled just yet though, as I'd like to learn a little more about them first.
Have a nice day !
