I'm trying to trade alts at cryptsy, but the bot price only seems to update every half-hour (multiple coins). What is going on?  It is placing orders based on old data, and ends up reverting its position when they don't clear.

The algo was adjusted to reflect 100 coins per block for the current LTC double reward. With LTC being one of the basis of the profit ratios, it cut all of them in half.  It's only cosmetic. The bots are still making good decisions.

Some coins convert on exchanges that lack a trading API. These are done by humans. That just means a second human hasn't reviewed the trade yet.

Haha, ooohkay.  

eh?

MEOW!

Cudaminer from Dec 1 doesn't work, at least on that hardware.  Downgrading to Nov 20 version fixed it for me.  Autotune also functions, and spat out K8x24 for me.  I'm running like so:

My amazon experimental setup, getting about 180kH/s combined GPU/CPU (which is obviously not going to turn a profit):

cudaminer -a scrypt -o $POOL_URL -u $POOL_USER -p $POOL_PASS -C1 -H1 -l K8x24
minerd -u $POOL_USER -p $POOL_PASS -o $POOL_URL -t 6
