MNG Futures (Micro Natural Gas): Tick Value, Expiries, Order Flow

MNG contract specifications

The contract unit is 1,000 MMBtu, quoted in U.S. dollars and cents per MMBtu. The minimum fluctuation is $0.001 per MMBtu, so one tick is worth $1 and a one-dollar move $1,000 per contract. It is cash-settled against the NG final settlement price of the corresponding month. Senzoukria's contract table holds the same tick and multiplier on the NYMEX venue code.

MNG last trading day and next contracts

The contract terminates one business day before the expiration of the Henry Hub Natural Gas (NG) contract for the same month.

Senzoukria's expiry engine applies NG's rule to MNG, so its picker lists the expiring MNG contract one business day after MNG has actually stopped trading; MNGV6's last trading day is September 25, 2026. On September 25, 2026 the picker already defaults to MNGX6 and still lists MNGV6 with an "exp" badge until September 28, 2026, the last day its engine gives that contract. For MNGX6, the default moves to the next listed month on October 24, 2026 (4 calendar days before October 28, 2026), and MNGX6 stays selectable with its badge until that date.

For MNGZ6, NG's last trading day moves to November 25 because November 26 is Thanksgiving, which puts MNG's on Tuesday, November 24, 2026.

MNG tick value and P&L arithmetic

• One tick = $0.001 × 1,000 = $1.
• 10 ticks ($0.01 per MMBtu) = $10 per contract.
• A $0.05 stop is 50 ticks: $50 per contract, $100 on 2 contracts.
• The same $0.05 on NG is $500 per contract.

Reading MNG order flow

With row resolution off, an MNG footprint has one row per $0.001 tick and prices carry 3 decimals. The fixed steps give 2 ticks = 0.002, 4 ticks = 0.004, 8 ticks = 0.008, 16 ticks = 0.016, 32 ticks = 0.032 dollars per MMBtu per row.

MNG is 1,000 MMBtu with NG's $0.001 tick, worth $1. It settles in cash to NG's final settlement price and keeps its own book, so NG depth and prints do not appear on MNG, and a size threshold chosen for NG lots means nothing in MNG lots.
