I just want to inform you, guys, that an interesting python open source software for backtesting strategy is available here
http://gbeced.github.io/pyalgotrade/

mixing both goxtool and pyalgotrade could make a good "recipe".

I'm looking for a 1 hour timeframe data history for MtGox BTCUSD

I tried http://bitcoincharts.com/t/trades.csv?symbol=mtgoxUSD&start=1335830400&end=1367366400

as 1335830400 is UNIX Timestamp for Tue, 01 May 2012 00:00:00 GMT
and 1367366400 for Wed, 01 May 2013 00:00:00 GMT

but Bitcoincharts only reply with data from 1367249267 (Mon, 29 Apr 2013 15:27:47 GMT)
