that should give you a start for your own research.

mm = market maker

arca and nite are...market makers

as for #4...you might wanna do some research on bagholders, uninformed/inexperienced people get destroyed playing these things, generally because they dont know what they are seeing, trust people that seem really friendly on msg boards and are playing their emotions and they get stuck in a bad position. A great cliche - if it seems too good to be true it probably is. Call me a hater or whatever, but dont get greedy and dont espect a cottage on St Croix from this thing. good luck to ya.
