I wish you luck, but I would suggest trying to actually work with the market instead of just hacking at it. It ends up with more zeros usually. Like I said, stacking it the way up with small chunks will usually make you much more. Don't put a $10k chunk on the ask and expect it to sell well, unless you are on something with a much higher price. That way you don't have to worry about bid whacking. Then you also preserve profit every step of the way, instead of just betting the farm all at once. And probably starting the sales on the runs would help, too.
