As it currently stands, the future host will be able to determine the tickets multiplier.
So a day or so before trading begins, the host will look at the trade lists and decide for her self what's the right number. For me, that's probably a 3 so I'll be entering three into that field in the host control panel. Others may want it to be 1 and others may want it to be 10 (or even higher.)
The part that is computed will be the ramp up over time as the days of trading progress.
