I could give you these sources:

Might be easy to adapt..

Java code doesn't help you? I released some of my code here:

https://github.com/ReAzem/cryptocoin-tradelib

The solution in my bot is a ChartProvder class, that caches the data from the exchanges. All bots request the data from this ChartProvider instance.

Nachdem sich hier die Sommerferien langsam dem Ende zu neigen, frag ich nochmal nach, ob noch jemand in der Region was mit Bitcoins macht und evtl. Interesse an einem Treffen hätte?

I think there are several USB-Stick distros for mining? That is more or less a btc OS?

But I think, we need something for mobiles, so people can buy and exchange btc everywhere? Like a p2p system, that more or less works like localbitcoins. Combined with the GPS functionality of smartphones, it would be easy to find someone near you to get btc?

I wrote it for me, but I'm willing to donate those dialogs to the openbitcointrader project, once it starts...

Is the number of trades higher now? Last time I checked, the number was too small, so I couldn't compute a graph?

So are you interested in such technology? Interested in helping to create the required infrastructure?

There are exchanges with lots of currency pairs. No need to move money from one exchange to another.

Well, I'm willing to contribute the sources, that I already wrote. Does that count?

You only considered technical trading. Triangle arb might work.

Is gentoo catalyst used? Would be cool to opensource the configs then...

Oh...another Java coder! Cool! Welcome!

Take a look at:

https://github.com/ReAzem/cryptocoin-tradelib/blob/master/modules/bitstamp/src/de/andreas_rueckert/trade/site/bitstamp/client/BitstampClient.java

It's not complete yet, but it might help you...

Uhm...are there any 'high-frequency' exchanges? Most of the ema-crossing bots make maybe 1 trade / day. So a bot, that makes 1 trade / hour is already 'high-frequency' in the bitcoin world, I guess. Most exchange will ban you, if you request data more often than every 15s, or so. So I guess bitcoin HFT is not comparable to 'real-world' HFT.

I still don't know, what you want to do? Code a tradebot? I'm working on such code, so I guess it's obvious, that I find it useful.

I'd like to do some arcace style games, but it seems that people will start cheating then by coding bots?

Added more exchanges...

I work on Java implementations of various exchanges:

https://github.com/ReAzem/cryptocoin-tradelib/tree/master/modules

Maybe a java implementation of the API would help, too?

Just an idea...

I work on exchange API implementations in Java.

Maybe we could collaborate?

Hey, I wrote some similar code!

I would add a graphical chart for the last trades and maybe the option for an automated order.

Like: if btc/usd > 100 then sell 5 btc

, or so...
