How long does skewing take to flatten your book?
You're long shares and skewing your quotes to work it off. At a mild skew you expect to net shares per minute (you sell a bit more than you buy). You could skew harder to net /minute, but a harder skew means selling further below fair, giving up more edge per share.
How long to flatten at each skew, and what governs the choice between them? Where does the randomness bite?
