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

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

[oda.krell]

Works now

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 !

Hello,

I just pushed a significant update, I hope it doesn't break anything...

Major changes are :
 * Added MACD chart
 * Added RSI chart
 * Added customization controls to many charts
 * Improved volume and relative volume charts
 * Optimized data decoding and processing

Have a nice week !

Nice site! 

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.

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.

Some people will want to see more than 1 year.

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.

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.

All the best, --jorge

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

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.

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.

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 !

Hello,

Much work happened on the data backend this week.
The ticker has been slightly improved, as well as the ticker API.
Besides, coinfloorGBP, anxEUR and anxGBP are now listed.

Cheers !

Hey

Great to see the latest updates.

Two requests:

1) (very minor) it seems that color choice (classic, thematic) isn't remembered after reload

2) (more interesting) any chance you can make graphs "vertically fill the space"? As in, if I close one of the graph windows, the remaining ones fill out the vertical space. Would be useful to see price or bid/ask graph in more (vertical) detail.

Hi oda, I just pushed an update which should address your requests (don't forget to reload the page twice to make sure your browser fetches the new version).
Note that you must click on the expand button in order for the chart to take all space available (I have to draw a better button for that, no success so far; it's the button right after the chart type selection).
Play with it a little to get the logic.

This is going to be nice eventually for technical analysis.

I'll keep an eye out for this. Thanks OP.

Hi bastilar, thanks for your feedback

Hey again

I was wondering, how difficult it would be to change the data presentation of coinorama to a more "traditional" and, ultimately, more informative way, where 'time period displayed' and 'time resolution' are not 1:1 linked?

As in: you can set a time resolution (daily, weekly, hourly), but you can zoom in/zoom out (within limits) given that time resolution.

Bitcoinwisdom is probably a good example for that behavior.

Probably quite a rework of your current site, but I'm just throwing it out as a suggestion to what could still be improved

Hi Oda,

You're right, data presentation should not be focused on time periods only, but also provides time resolution.
Zooming and scrolling aside, this can be implemented without much new development. And the first step towards this evolution would probably be to display both time resolution & time period.

I'll try to activate the first step by the end of the month, but cannot make any promise for going further at the moment as my TODO list is pretty full.

Regards

Hey

Very cool you're not dismissing the idea entirely. No hurry to implement it, imho, it's a major change in presentation, and should probably be thought through well before you decide on a way to to do it.

P.S. Your site rocks.

Hello

Coinorama is very nice !!!
found it about a month ago
 
I really like the graph of total volume (in BTC) of major exchanges

Is it  much to ask for a total volume in USD too , 

[naddison]

Nice site. I've been using it for a while now

Is there something wrong with the AnxPro BTCUSD price? It's no longer matching the last price in the AnxPro API ticker
