SierraChart bridge - Realtime Bitcoin charts [v0.5] (MtGox, Intersango, ...)

[macboy80]

• 2. Download SierraChart feed for bitcoin markets.

The above link to sierrachartfeed-0.3.exe is giving a 404 error... I've got the actual software, just not the feed for bitcoin markets.

Oh, damn, I forgot to upload it to new server. Fixed.

Hi slush. It seems MtGox has changed how their websocket works. I'm no expert, but here is the what was said on #mtgox regarding this.

For now, realtime update is not working because of this change it seems.

<shockdiode> websocket is officially deprecated now?
<MagicalTux> shockdiode: yep, replaced by socket.io server
<MagicalTux> which is more stable
<MagicalTux> but not using the same protocol
<MagicalTux> client libs are however in most languages, however
<shockdiode> when will that be up?

<MagicalTux> [18:23:22] <shockdiode> when will that be up? <- IT IS
<molecular> MagicalTux, any doc/wiki/??? on socket.io server?

<MagicalTux> molecular: http://socket.io got a lot of doc
<MagicalTux> it's basically the same websocket data, passed through socket.io

<molecular> MagicalTux, thanks. so you merely switched the transport layer? everything else like before...?
<MagicalTux> molecular: yep, switched transport layer, which will allow us to make it work in any browser

When you run the bridge, this error shows up now.

Exception in thread Thread-1:
Traceback (most recent call last):
  File "threading.pyo", line 525, in __bootstrap_inner
  File "pywsc\receiver.pyo", line 41, in run
  File "sierrachartfeed.py", line 90, in ticker_update

I am getting this error as well when running sierrachartfeed:

Exception in thread Thread-1:
Traceback (most recent call last):

KeyError: 'channel'

Also -w fix does not work, gives http 503 error.

Any help, anyone?

[slush]

I don't know how to fix mtgox websocket - https://bitcointalk.org/index.php?topic=5855.msg623526#msg623526 - any help is appreciated.

About 503 error - it's something on bitcoincharts. However if you leave sierrachartfeed running for some time, it will download data succesfully - I'm using feed with -w right now.

Thanks,

I cleared my gox.scid file, and am using the -w option right now, says its downloading historical data. Will wait and see.

[slush]

I cleared my gox.scid file

This wasn't necessary, you probably only lost some history because bitcoincharts, if I remember well, provide only last 30 days.

So it looks like still getting those intermittent http 503 errors.

Have been using using the browser based charts for now.

Thanks for your help.

As tcatm told me it's rate limiting on his side for 1rq/minute. Besides that annoying error message, it is working fine, only up to 60 second delay.

Mtgox websocket isn't working for me for some reason and nobody can give me any advice, so I'll remake code to use bitcoincharts socket interface, which is only few seconds after markets (because it is using polling to markets internally).

So you are building a newer version of sierrachartfeed? If so, many thanks.

Version 0.4 released, fixes non-working streaming from MtGox. It is now using socket interface to bitcoincharts instead of MtGox's socket.io.

Download: http://mining.bitcoin.cz/media/download/sierrachartfeed-0.4.exe

Pros - sierrachart now supports live streaming of all bitcoin charts, not just MtGox.
Cons - there's currently implemented only polling between bitcoincharts and mtgox and chart updates are delayed 5 seconds in average. But tcatm is working on socket.io support on his side, so it will gets better soon.

Enjoy! :-)

Thank you Slush for updating this. Can you add your bitcoin add to the front page so I can buy you a beer for your troubles?

I think it used to in your sig, but no longer there.

[slush]

Litt, I put it back to my signature.

P.S. I prefer wine :-).

I sent you a few coins out of my mining income to show my appreciation. I would like to ask others to do the same if you love using sierra chart and appreciate what Slush is doing for the bitcoin community for free.

I personally prefer wine myself, but buying another guy beer just sounds more masculine? haha Again thanks for doing this Slush.

[slush]

Litt, thank you a lot! You actually bought me a bottle of wine instead of a glass ;-).

Today my connection to bitcoincharts freezed without raising any exception. I'll need to elaborate and then I'll release fixed version. I'm also learning Qt (for working on electrum client) so I'm considering to do small homework and remake SC bridge into small app with tray icon instead of weird hacker's tool for commandline.

[slush]

bitcoincharts.com interface was broken, it's working again (thanks tcatm!)

[czebrda]

Is it just me or the feed stopped working? All I get is

Code:

sierrachartfeed-0.4.exe
Loading data file c:/SierraChart/data/mtgoxUSD.scid
Downloading historical data
Opening streaming socket...

EDIT
I guess it might have sthin to do with bitcoincharts not working https://bitcointalk.org/index.php?topic=56569

[slush]

Yes, streaming of mtgox from bitcoincharts is down because of recent huge trading volume on the mtgox. I believe it will work again soon...
