I believe that "post no preference" feature restricts ARCA to using Selectnet Broadcast orders. The essence of Archipeligo is that it's a selectnet preferencing engine, of course. It goes out and figures out which MM's have been to the bid/offer most frequently, etc. and preferences them for you faster than you could do it. It has a lot of other tricks up it's sleeve too which I am still learning about(see ARCA tutorials; discussion invited!).

The option you mention sounds pretty useless considering how Selectnet trades nowadays - you need to let ARCA auto-preference them in sequence, so they will HAVE to fill you, if they're setting there, at least for part of your shares.

There may be special conditions where you'd want to use that option, but I'm not sure what they'd be off the top of my head.
