NYMEX Post-Close Trading Session Rules

DATE:
May 8, 2001
===========================================================

This Notice advises Members and Member Firms of changes to the two post-close 
session rules applicable to the NYMEX Division.

! As a result of amendments to both rules, the post-close sessions generally 
offered Monday-Thursday will be the same as the Friday sessions with two 
exceptions.

! Monday-Thursday. These sessions will start at 3:25 p.m. and will be two 
minutes long.

! Fridays. These sessions will start at 3:30 p.m. and will be five minutes 
long.


End of Week Post-Close Trading Session (Rule 6.57A)

As a reminder and as a follow-up to a Notice distributed last week, please be 
advised that beginning on Friday, May 11, 2001, a number of amendments to 
NYMEX Rule 6.57A, the NYMEX End of Week post-close trading session rule, will 
become effective. The new version of this rule is attached below.

For Friday post-close sessions (and for post-close sessions the day before a 
mid-week Exchange holiday) the following changes will be in effect:

(1) Eligible contract months will be expanded from the first four to the 
first 12 consecutive listed contract months.

(2) The sessions now will be 5 minutes in duration.

(3) The trading range for these sessions will be expanded by adding the 
following ticks above (below) the
daily high (low) for the applicable contract month (provided that this 
expanded trading range does not violate the maximum permissible price 
fluctuation limits then in effect):

Crude Oil  20 ticks
Heating Oil   50 ticks
Unleaded Gas   50 ticks
Natural Gas  50 ticks


Monday-Thursday Post-Close Trading Sessions (Rule 6.57)

In addition, please be advised that beginning on Monday, May 14, 2001, a 
number of amendments to NYMEX Rule 6.57, the Exchange,s post-close trading 
session rule for days other than Fridays, will become effective.  The new 
version of this rule is attached below.

(1) Eligible contract months will be expanded from the first four to the 
first 12 consecutive listed contract months.

(2) The trading range for these sessions will be expanded by adding the 
following ticks above (below) the
daily high (low) for the applicable contract month (provided that this 
expanded trading range does not violate the maximum permissible price 
fluctuation limits then in effect):

Crude Oil  20 ticks
Heating Oil   50 ticks
Unleaded Gas   50 ticks
Natural Gas  50 ticks

(3) Customer participation will be expanded to the same extent as is 
permitted for the End of Week Post Close Session. Please note that any order 
submitted during the RTH session, including but not limited to resting orders 
such as stop orders, limit orders and good until cancelled (GTC) orders, will 
be deemed to have expired as of the end of RTH for purposes of this Session.  
Accordingly, in the event that a market participant with such an expired 
order seeks to participate in the Session, a new order must be submitted.

(4) As a consequence of the expanded trading range and customer 
participation, trades done during this period will be price reported on PRS.

Finally, please be advised that, as a matter of practice, the Exchange does 
not currently offer post-close trading sessions for Propane futures contracts.

If you have any questions concerning these changes, please contact George 
Henderson, Vice President, NYMEX Floor Department, at (212) 299-2071; Rob 
Stasi, Manager of Trading Floor Systems, NYMEX Floor Department, at (212)
