Acumulated ask/bid graph over mtgox depth of market

[warpi]

Hello,

I just developed this site to make it easier to see how stabile the USD/BTC rate is.

http://warpi.net/bitcoin/

If you have any ideas of improvements etc,, please post them here!

Happy bitcoining!

Now I added the center value in USD/BTC.

Two features that would be nice:

1.)
Would love to be able to adjust the width and height and have the image display those details.

For instance, when I'm considering buying, I care mostly about the next $200 of supply, not the next $100,000.

2.)
Periodic refresh (or w/websocked immediate refresh with each new datapoint :-) )

Great job with this!

Ive added this now. Just trying to fix so that the spread automaticly adjusts aswell.

I will add this. Thanks and please consider donate 1 BTC

Another 1 BTC donated to you.

Another 1 BTC donated to you.

Thx again There is still some improvements to be made, but I will continue with them when I come back from work. Cya

warpi, can you record the history?

It would be possible to construct three-dimensional "trench" and see how a change offers. (Many of us believe that there is collusion and rate changes synchronously)

That would be awesome!

Sorry to ask such a noobish question (I've never engaged in any kind of market activity), but how does one interpret a graph like this?  What it is supposed to tell me?  What is "market depth"?

[Yurock]

how does one interpret a graph like this?  What it is supposed to tell me?

Let's suppose there is an order selling 25 BTC at rate 3.45. If you need 25 BTC or less, you buy at that price. If you need more, say, 1000 BTC, you'll have to buy them at higher rate, 3.5. By doing so, you are "moving the market", because next ask order available for others will be at 3.5.

What is "market depth"?

Isn't a market depth graph already available at mtgox, and a few other websites?  I guess I fail to see what this one offers over the other graphs.  What is meant by "accumulated" market depth?

[Yurock]

what this one offers over the other graphs.  What is meant by "accumulated" market depth?

Y coordinate is the sum of values of all bid orders from certain rate up to the highest bid rate, or sum of values of all ask orders from the lowest rate to certain rate.

Gotcha, thanks.

The accumulated market depth chart is already available on the MtGox megachart.

A three-dimentional "trench" (showing changes in the accumulated market depth over time) would be fascinating to see.

This chart allows me to zoom in just for the range that I'm interested in ...
   i.e., "how much supply is there for the next $150 worth of buying", for instance.

The script is very sad, when Mt. Gox is down.

Warning: fopen(http://mtgox.com/code/data/getDepth.php) [function.fopen]: failed to open stream: Connection timed out in /home/warpinet/public_html/bitcoin/index.php on line 5

Warning: fclose(): supplied argument is not a valid stream resource in /home/warpinet/public_html/bitcoin/index.php on line 7
Warning: Division by zero in /home/warpinet/public_html/bitcoin/calc.php on line 41

I suggest some error handling.

Now I have atleast removed all error messages

Looks like the service is not functioning. 

The exchange made some changes as a result of the DDoS attacks -- perhaps one of those changes introduced the problem (e.g., need to now access the trade API using https:// ?)
