Topic: Coinorama.net - BTC markets & network charts + blocks list - page 7. (Read 24005 times)

Thanks again for your nice feedbacks and comments !
I plan to implement those features (exchange data sum + cookies) this week-end, it will mark the first month anniversary of Coinorama

Looking better and better I like the "merge price&ask/bid ratio" option.

Still think it would be nice if there would be the option to *sum* the exchange data. With the current mtgox dominance, that probably means the resulting graph will only be slightly different from the mtgox chart alone, but it'll become more useful as mtgox loses market share. Mainly the combination chart of price + bid/ask ratio would be very useful to see summed up (weighted by volume, obviously).

EDIT: wait, one thing: is there a chance to store the user choices (time frame, choices under settings) in a cookie? Whenever I re-open the site, it goes back to default view (1h interval, show moving averages). Don't know if fiddling around with cookies is non-trivial or not :/

The Kraken exchange is organizing a trading tournament to test its infrastructure.
Thus, their trading data are off the main market and should not be compared to others.
I put Kraken out of the multiple exchanges display, but its single view is still available for tournament participants.

Awesome! Thanks for the heads-up, .

Thanks ! Yeah, I plan to add Litecoin support. Probably, by the end of this summer 

This is an awesome site -- I love how it looks! Any chance of releasing clones of this for other coins as well (Alt/BTC)?

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

Yes and when I saw the "upgraded" message I thought "What are the chances this happens right now?" I mean I checked it for 20 seconds today - right then...

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 ?

Great job, keep it up! But I was refreshing when you did that! (Really) 

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 !

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 

Yeah, great idea ! I'll try to play with a couple of parameters and improve that.

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 done with candlesticks, I'll enable it in a couple of hours.
It's not perfect, but usable.

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.


Heh, I was wondering how popular your service was so far. I'll mention it a few more times on the speculation forum.

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).

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.

I don't know which indicator per say to use, but if you were to go through some of your more favorite ones (e.g. - MACD, when EMA's cross, money flow, etc.) and somehow connect
that to your bid/ask ratio and then back test it and see where it was meaningful. Know what I mean?

Thanks again for the description. It is interesting to look back (two weeks is your max) and see how the bid/ask ratio came down recently and is going back up now. It would be
interesting too look back a few months to see what it looked like during the big rise and boom, etc.

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.
