U.S. natural gas futures were holding steady in early trading after another test of the $3 level ahead of Monday's October contract expiration. The market remains closely tied to physical supply and demand dynamics across key U.S. and global energy regions.

Henry Hub Natural Gas futures are among the world's largest physical commodity futures contracts by volume, with approximately 400K contracts traded daily and 1.7M in open interest. The contracts are connected to the spot market and offer nearly 24-hour electronic access via CME Globex and related venues.
