I made a version of this already: http://bitcointalk.org/index.php?topic=537.0

Yeah when you go to pay it is one of the options: http://www.thefarwilds.com/order/order.php?name=jed&id=53

I made a Bitcoin payment button for my game and thought I might as well make it generic so anyone can use it. Basically if you paste this snip-it of code into your site then you can start accepting Bitcoins.

More details are here:

Let me know what you think about it and if you have any questions.

Yeah I know. I'm 90% done with the code part of it. Just seeing if someone had already made a button image before breaking out photoshop.

So wait to code yours since hopefully you can just use mine :)

I mean an image. You know a nice one that people can put on their checkout webpages.

Yeah I agree. I posted before I saw this but it would be nice to get events. I'd like to get them all not just for addresses I ask about.

Hi it would be really nice if bitcoind could be configured hit some URL or run some shell script anytime it gets a transaction in with over a certain number of confirmations. It would be nice if it passed this script the label,address, and amount.
This would make writing any kind of payment processing much nicer. It would make it event driven rather than having to poll bitcoind all the time.

Made some improvements:

Optional Email notifications for trades.
Sorting your open Orders and past trades.
Rough Depth of Market data although it still has some issues.

This is when you place an order at the default price? That default price is only set if there is a counter offer at that price. So It should be filled. maybe there is a floating point rounding issue. Try placing it slightly above or below.

NewLibertyStandard: It seems like you should use both. right now the best place to buy is on his exchange and the best place to sell is on mine. Last price on there was .061 and last price on mtgox was .081 so you would be getting 32% more for your BTC on mtgox. Which dwarfs the 2% spread.
There are some real arbitrage opportunities right now!

I'm hoping that we can somehow link the 2 exchanges.

They can be restored.

Yeah bartering is legal in the US.
I was wondering at what point a thing switches from being considered a commodity to being a currency. There is an exchange that sells pork bellies for example and that is totally legal. I feel like bitcoins can just be considered a commodity and thus be legal to trade/exchange in the US.

Big time. I'm really hoping bitcoin makes a huge dent in them. It annoys me so much that they get 5.9% for running one UPDATE statement in their database.

Nice work! Good to get this stuff organized early. I implemented it (hopefully correctly) with my exchange.

I have a question though about currencies that are not traditional. How should we list them? For example I want to add a virtual currency from a game. Should I just make up a reasonable pair symbol that isn't taken?

For this: bitcoin/fxchange.pairs.json

Yeah paypal's fee is 2.9% + $0.30 USD

This is a great idea! This will really spread the word I think.

InterArmaEnimSil:
We make money by keeping a 2% spread between the buyer and seller. But the price you buy or sell at is the price you get. The way it works is if you enter a sell price of X the buyer sees the price as X*1.02. So your trades will complete at the price you see on your order the other guy will just be agreeing to a slightly different price.
Adding this info to the site now...

Withdrawing: Yes you only need to enter in the fields pertinent to your withdraw. I'm going to make this form dynamic and better tomorrow. All withdrawals are manual for a few days until I'm more certain there are no major issues. But paypal and BTC should both become automatic soon.

Adding both types of Funds is automatic right now.

Just curious are these happening?

Great send me an email when you get a chance or chat me up in the irc channel.

This was just a display bug and is fixed now. Let me know if you notice anything else.
