  • Minimum margin requirements have been recommended by the com. exchanges listed. Spread margins are intra-market only.
  • Consult your broker for changes that occur during spot months.
  • Contact your broker for individual brokerage hour margin requirements.
  • Contact your broker or the exchange for information on variable trading limits.
  • Price limitations are imposed by the various exchanges to prevent extreme price changes in any one day. When prices reach the trading limit, trading beyond that limit is stopped for that day. In nearly all markets, the Board of Directors of Governors has the power to change the limits in emergencies. in the current month, the limitations are broadened in certain futures contracts by permitting wider price ranges and in others by removing limitations entirely.
