# Micro Henry Hub Natural Gas Futures (MNG) Contract Specifications

#### What you're trading

The Micro Henry Hub Natural Gas future (MNG) is 1/10th the size of NG and tracks the same Henry Hub natural gas benchmark, but settles financially rather than requiring physical delivery. MNG is designed for traders who want exposure to U.S. natural gas price movements without the notional size or delivery complexity of the full NG contract — particularly useful during winter heating season or around storage reports, when NG can make outsized moves.

#### Contract size

1,000 MMBtu of natural gas (1/10 of NG). 

#### Tick value

Minimum price fluctuation is $0.001 per MMBtu, and each tick is worth $1.00 per contract. A $0.01 move equals $10, and a $0.10 move equals $100 per contract.

#### Trading hours

CME Globex: Sunday 5:00 p.m. CT through Friday 4:00 p.m. CT, with the 4:00–5:00 p.m. CT maintenance halt Monday through Thursday.

#### Settlement type

Financially settled. Trading terminates one business day prior to the termination of the corresponding NG contract month, and MNG settles based on the daily settlement price of the corresponding NG contract. No physical delivery.

#### Margin snapshot

MNG margin is roughly 1/10th of NG. Given natural gas's historical volatility, keep a buffer above maintenance even at this smaller size.

| **Initial margin (overnight)** | ~$300–$650 per contract (approximate; highly volatility-dependent) |
| --- | --- |
| **Maintenance margin** | ~$270–$590 per contract |
| **Day-trade margin** | Broker-set; often a small fraction of overnight margin |
| **Notional value (reference)** | ~$3,500 at $3.50/MMBtu |

*Margins change with market volatility and vary by broker. The figures above are approximate and for reference only — always confirm current requirements with MetroTrade support or on the CME margin page before trading.*
