A better (?) way to visualize Mt. Gox trades

[stakhanov]

In the interest of market transparency, I think it's important for everyone to be able to understand as much as possible what's going on in the currency exchanges.

Which is why I made the following chart:

http://sd-12155.dedibox.fr/~joel/btc/mtgox.png

In contrast with traditional charts, this one shows the volume of each trade (the area of each circle is proportional to the amount of money exchanged). The circles are transparent to allow viewers to appreciate the density of trades at a given time point.

Hopefully this chart should allow people to better understand what's going on the next time the exchange rate swings widely, and to differentiate small jitter from big movement. Assuming I didn't bork my cron command, it should get updated every hour.

Whoa, awesome

I would like to see a real-time version of that.

[RodeoX]

Nice work brother!

[NO_SLAVE]

That is very nice my friend. Id like to talk to you about developing some real time charting apps.

[wumpus]

Very cool and useful.

Speeder: me too, this needs a realtime, zoomable/pannable, version.

How about some block chain visualizations?

Sort the blocks by their last use time, then make an animation out of this, where the block visually flies to the front of the line.

This would nicely show both total bitcoin activity, as well as hoarding.

By popular demand, I'm willing to open source the code for the chart if I get 10 BTC at the following address:

Everyone can verify if the bounty has been paid with blockexplorer.

lol, donations work the other way round. you have a service and then you receive tips.
not someone pays you >$200 and then you deliver something.

He already does. A chart that was linked up above. It is also within his rights to ask for donations. Don't understand why ridicule is needed in this case. Unless that's just how you operate.

Excellent.  I love it.  However, I would like for an option to view it where bubbles are summed.  Such that the contour revealed how much was traded at that time.  Many small trades and one large trade appear quite differently.  But those two mean the same thing to me.

I agree, a way to group transactions would be nice. But you would necessarily lose some info.

Offers like this are legit imo. Of course if you are going to hold 7BTC if it doesn't make it people will be irritated. Better to escrow with someone else and only get paid if it makes it in some certain time.

I would probably refund the people who gave or make it open-source anyways after a while.

BTW, does anyone know if there is a simple way of refunding people with bitcoin, ie. sending the coins back to where they came from?

[Mark Oates]

That's a very nice chart

The part I'm most curious about is where do you get the raw data from mt gox?  Is there a complete 100%-time acurate database available of the transactions (so far) or are you cron-ing the mt gox trade data?

For now it's simply the Mt. Gox trade data, I'm not even storing it.

What a great way to visualize Mt Gox trades!  What language did you use?

Python with matplotlib. It was actually pretty simple

I'm also interested. I came across this question when thinking about how a political party could use BTC for donations and membership fees. Any payments that can not be attributed to a real person would need to be rejected so either given back or handed over to the president of the Bundestag in Germany for example. Actually having to give it to the president would be fun as in return that guy would have to somehow accept/take BTC, wouldn't he?

[toey]

It looks great! Would it be worth colour coding buys/sells?

[PcChip]

maybe red for one, blue for the other, and a heavy mixture would make purple?

Or something along those lines
