Didn't mean to take over your thread, lol. But this is an interesting discussion.
Please, be my guest
I think that bots try to extract as much information as they can and use the information they consider useful. I also think most bots are probably neutral WRT direction (though some may be momentum driven).
My assumptions about bots
1. Neutral WRT direction. They like to be square.
2.They have a certain number of units they will buy or sell usually, which is a function of liquidity.
3.They are happy to bit 1 Satoshi more than me up to a level.
4.This level (i.e. the amount they will pay or sell at below the bid or offer) changes depending on their own position.
Not so sure about 4 but I assume it is true, and it seems to be in practice.
Not totally sure about 1 either
