In setting margins levels, the Chicago Board of Trade Margin Committee along with the CME Clearing House monitors current and historical price movements covering short-term, intermediate and longer-term data using statistical and parametric and non-parametric analysis. Futures maintenance margin levels are typically set to cover at least the maximum one-day price move on 95% to 99% of the days during these time periods.
