I apologize for the semi-cross post, but I wanted to specifically highlight for miners my new post on the main BitcoinBuilder thread:https://bitcointalk.org/index.php?topic=67835.0
BB now supports not just automatic scheduled buying of BTC
on your mtgox account, it also supports automatic scheduled selling of BTC
Which, although anybody of course could
use it, seems of most relevance to miners who generate a rather steady stream of BTC
they need to convert into fiat to pay their hosting/electricity bills!
Also, BB now supports buying/selling at not just the market price, but also the highest bid, lowest ask, 24 hour high, 24 hour low, 24 hour average, and 24 hour volume-weighted average. Of course, placing any order besides a market price might mean your order doesn't execute, but them's the breaks!
Check it out, it's 100% free and only needs "trade" API access to your mtgox account.https://www.bitcoinbuilder.com/
