LOG: Trading-volume Ratio of top Exchanges

[andes]

(Disclaimer: I have no connection whatsoever with MtGox or Tradehill or Bitcoin7. Please trolls and spammers, dont flood this thread).

I invite you people to regularly post the trading volume ratio among the 3 biggest Exchanges (USD) for future analisys.
Post:

-Date
-UTC Time (GMT Time) as seen for example in http://bitcoincharts.com/markets/
-Volumes for the exchanges
-Source
-Percentage Ratio (volume of an exchange * 100) / (sum of volume of all exchanges sampled)

Suggestion: Post data in blue to make it easier to find amids the comments.

It dosent hurt if multiple people post values in a single day (as posts are forever-editable, more post by different people guarantee a better integrity of the data).

(Note: If there is a website where you can check out this historial ratios, please point out, as this thread would have no value as a log, but only to comment on this indicator).

I noticed the last two days after the re-opening of MtGox, the ratio between MtGox and Tradehill volume was very close to 0.10, for 48 hours.

Today the ratio is 0.14.

Today tradehill has 14% of the volume.

That's not correct.  Tradehill's volume is 14% of Gox's currently but 'has' only:
2727 / 19024 + 2727 = 12.5%
of the total volume.

Corrected, thanks.

The entrenched primacy of Mt. Gox is retarding the market. Somebody big should be bidding up the TH price to bring arbitrage volume over.

Changed the source to Bitcoin Watch (previously I was using Bitcoin Charts). It is more accurate to calculate ratios out of the volume in the last 24 hrs rather than the volume since midnight UTC, due to the uneven distribution of trading during the day.

This is encouraging.

Not really. Look at the volumes.

I don't particularly care if they are all low.  Bitcoin has still not yet even made a blip on the radar of 99+% of the population out there.
I just care that it's more evenly distributed between the exchanges (i.e., TH and B7 market share is increasing).

Warning: I strongly suspect the data in Bitcoin Watch or Bitcoin Charts is wrong. Right now, Bitcoin charts shows a MtGox Volume of 17799 since 0:00 UTC. Yesterday the volume was very low, so its impossible that the 24 hrs volume that Bitcoin Watch shows right now (41339) can be right.

The trades at MtGox in the last 4 hours of yesterday were not 140% of the trades in the 20.5 hours of today. Whoever manages those sites, check your algorithms, as something is not adding up here.

EDIT: I checked the charts of the last 48 hrs, and in fact there was a strange anomaly in trading precisely in the last 3 hours of yesterday, so it is perfectly possible that 70% of the daily trading could happen in mere 3 hours. This kind of trading activity does not happen very often though, and to me it was just an artifact caused by bots reacting to a sudden big sale, and it does not reflect a human buying pattern.



I wonder if looking at traded volumes makes any sense at all, when automatic trading is present. The volume could mean nothing. Any thoughts from more experienced traders?

Here's something weird. The google gadgets for these sites (got them here: http://forum.bitcoin.org/index.php?topic=10689.0) show Tradehill with twice as much volume as mtgox:

MtGox:
Last Price: 14.023
Buy: 14.023
Sell: 14.0499
High: 14.72299
Low: 13.76
Volume: 32014

TradeHill:
Last Price: 14.2
Buy: 14.01
Sell: 14.1998999998
High: 14.7399
Low: 13.75
Volume: 60613.4925944293

Probably the Google gadget is getting data from the wrong source . . . .
