MGC Futures (Micro Gold): Tick Value, Expiries, Order Flow

MGC contract specifications

The contract unit is 10 troy ounces, quoted in dollars and cents per troy ounce. The minimum fluctuation is $0.10 per troy ounce, so one tick is worth $1 per contract and a one-dollar move is $10. Open contracts are settled by delivery during the delivery month. Senzoukria's contract table holds the same tick and multiplier on the COMEX venue code.

MGC expiry: first notice day and last trading day

No trades are made after the third-to-last business day of the delivery month. Delivery can take place on any business day of that month, so notices begin on first notice day, the last business day of the previous month.

Senzoukria's picker does not wait for either date. Its expiry engine lists a metal contract only until the third-to-last business day of the month before delivery, two business days ahead of first notice day, so that a deliverable contract is never proposed as the default. On September 25, 2026 the picker already defaults to MGCZ6 and still lists MGCV6 with an "exp" badge until September 28, 2026, the last day its engine gives that contract. For MGCZ6, the default moves to the next listed month on November 22, 2026 (4 calendar days before November 26, 2026), and MGCZ6 stays selectable with its badge until that date.

MGC tick value and P&L arithmetic

• One tick = $0.10 × 10 = $1.
• 10 ticks ($1.00 per troy ounce) = $10 per contract.
• A stop of $5.00 per troy ounce is 50 ticks: $50 per contract, $100 on 2 contracts.
• The same $5.00 on GC is $500 per contract.

Reading MGC order flow

With row resolution off, an MGC footprint has one row per $0.10 tick. The fixed steps give 2 ticks = 0.2, 4 ticks = 0.4, 8 ticks = 0.8, 16 ticks = 1.6, 32 ticks = 3.2 dollars per troy ounce per row; grouping keeps totals exact but moves the POC from a price to a row.

MGC is one tenth of GC: same price, same ten-cent tick, $1 per tick instead of $10. It is a separate COMEX order book, deliverable like GC, and its prints are counted in MGC lots, so a large-order threshold tuned on GC depth has no meaning here. As on GC, ten ticks make a dollar and no power-of-two row step lands exactly on $1.

Using MGC in Senzoukria

• Symbol picker on a Rithmic or Databento CME source: type MGC; on September 25, 2026 the listed contract is MGCZ6 (December 2026).
• Heatmap and DOM show that contract's book, with COMEX as the venue in the ladder header and prices printed with 1 decimal, the precision of the tick.
• Replay lists MGC in the Metals group. In the automatic backtest, set Point value ($) to 10, the dollar value of a one-dollar move; the field defaults to 2.
