Set a minimum or maximum in the Min and Max exposure columns and apply. SaberSim re-diversifies your portfolio to meet the numbers you set.
Auto Apply Exposures reruns the diversifier after every change. Leave it on to see each adjustment immediately, or turn it off to batch several changes and apply once.
Global Max Exposure caps every player at one number across your whole portfolio.
If SaberSim can't meet an exposure from the current pool, rebuild. The rebuild carries your exposures and produces a pool that can.
