2. Yes. we are working on optimizing this right now. There are a couple of different ways to go with this. Using multiple exchanges to help avoid an instant "sell order" flood is apparently the most effective method for the time being. Good trade bots helps as well, but trading is an art that very few people can do with any kind of profitable consistency. To put it in simple terms. We don't want to gamble with other peoples money.
The point of a bot (or script, whatever one calls it) is not for "trading" or gambling with people's money, but is to prevent such flood by selling in low volumes, multiple times throughout the day.
