One month after opening the beta it's my great pleasure to announce that MPEx has left the paper-and-monopoly-money phase and is now live, churning away bitcoins and assets.

So why do you want to use it?

Reason #1. 0.2% sell side fee, no buy side fee.

Reason #1.1. You can slash that even further if you qualify for Market Maker. Ask mircea_popescu (#bitcoin-otc-eu on freenode) for details.

Reason #2. Free PUSH of assets. That's right, you want to move stocks around and you know your counterparty's fingerprint go right ahead. We charge you for the matchmaking we do, but we don't charge you for the matchmaking you do yourself.

Reason #3. Huge market depths. We're talking thousands of BTC.

Reason #4. Security. Seriously.

Reason #5. Uptime.

We're also looking for solid companies to launch IPOs, talk to the same mircea_popescu.

And here's to a happy 2012, the year of Bitcoin.

Have I got this right, the ask price from the issuer for ETF shares for gigamining bonds is over 10 times higher than the trading value of the underlying assets on GLBSE?

ASK: 0.01770000

900 gigamining bonds = 900,000 F.GIGA.ETF
1 gigamining bond = 1000 F.GIGA.ETF

--> Asking 17.7 BTC per underlying bond!

Your security may be great, but currently usability is cumbersome. I don't have the technical know-how, but is it possible to script the operations, such that one could download a program and import their gpg key into it. It would query MPEx for assets and orders, and could then sign and submit orders?

Such a program would also allow automated pricing of orders (e.g., to adjust for FX fluctuations). In the current state MPEx would not be suitable, because of the need to enter each order manually.

I'm afraid the website needs serious usability improvements and a UI revamp.

I'm not trying to put you off, I'm trying to give productive input. I hope it doesn't come out the wrong way.

Whoops hehe. This has been since fixed.

On the other score: there are a couple people working on bots for it atm.

A first step would be something like
Quote
$echo "STAT" | gpg --clearsign | gpg --encrypt --armor -r F1B69921
especially if you have gpg-agent running. You could conceivably turn that into a bash script taking a parameter, too.

Note that there's absolutely no need to enter the order manually, you can just POST to the script (use curl or whatever you prefer).

PS. The first link in your sig doesn't work anymore.

This is quite interesting. There is an EFT on my bond!

When it starts to get much more technical than that I start getting lost. I'm sure it's a piece of cake for some though, so hopefully someone (MP?) can release something like it that make MPEx easier to use.

Thanks. I will remove it.

Simple page + GPG security ftw
I wish there was a bitcoin exchange site like this as well, MtGox lite but a Tor hidden service, backed by LR or something and using web of trust model

If you're on linux:

Quote
$sudo apt-get install gnupg-agent
$gpg-agent --daemon
$echo "BUY|S.XXX|1000|5000" | gpg --clearsign | gpg --encrypt --armor -r F1B69921

That way the CLI directly spits out the gpg stuff you need to paste into the box. If you would rather it also posts it directly you can replace that last line with

Quote
$echo "BUY|S.XXX|1000|5000" | gpg --clearsign | gpg --encrypt --armor -r F1B69921 | curl --data "msg=@-" http://polimedia.us/bitcoin/mpex.php

(haven't tested but should work roughly speaking).

Quote

YE!

Would be pretty cool to see a gpg based exchange for sure.

Ahh, very nice Azelphur!

Barely a day has passed and there's already github commits and whatnot. Excellent!

Thanks. Just got this set up. It makes it easier. A GUI would be better still. I'm sure it will come. GLBSE started as a CLI too.

From now on you can trade BTC/USD options on the MPEx infrastructure. Of particular interest is the newly added command SPLIT. Quoting from the FAQ:

Quote
SPLIT, as in SPLIT|{btc}|{option id}, which allows you to split a number of whole BTCs into CALL-PUT pairs for a given strike. Say you want to sell short 100 CALLS struck at 5.0 expiring this month. Provided you have 100 BTC in your account you go SPLIT|100|050T and voila, you now have 100 CALLS @5.0 (and a number of PUTS @5.0 based on the strike/current BTC/USD ratio), which you can sell. At the month's end you will receive the 100 BTC back, minus any costs resulting from exercises.

As you can see, this is a significant improvement over the way short selling works on the old MPOE site.

As a result the MPOE site is being retired. Customers currently holding options (long or short) on MPOE can ask to be migrated to MPEx (provided they have a registered key), but are not required to do so: contracts will be honored as they are at any rate. MPOE will stop taking new orders sometime in the coming months.

Proudly announcing the new candlestick graphs, visible on individual asset pages (http://polimedia.us/bitcoin/mpex.php?mpsic=F.GIGA.ETF for instance).
