Micro contracts (MES, MNQ, M6E)

Micro contracts are smaller-sized futures listed by CME alongside the standard E-mini and currency contracts: MES tracks the S&P 500, MNQ the Nasdaq-100 and M6E the euro, each with a lower index multiplier than its larger sibling. They are separate instruments with their own order book, executions and volume, not a fractional view of the larger contract.

What a micro contract is

CME lists a family of reduced-size futures that mirror larger contracts on the same underlying. MES is the Micro E-mini S&P 500, MNQ the Micro E-mini Nasdaq-100, and M6E the Micro euro contract. Each micro follows the same price as its full-size counterpart, but the amount of money per index point (the multiplier) is smaller, so the same move in points is worth less per contract. The exact multiplier, tick increment and tick value are published in the contract specification for each product.

  • Same underlying and quoted price as the larger contract.
  • Smaller multiplier, therefore smaller tick value and lower margin per contract.
  • A separate listing: its own symbol, its own order book and its own tape.

Why the distinction matters for order flow

Because a micro is a separate instrument, a trade printed on MNQ is not printed on NQ. A footprint chart, a delta series or a volume profile built on the micro describes the micro's executions only. Counts in contracts do not translate between the two either: one E-mini contract carries a much larger notional than one micro, so a level showing the same number of contracts on both books represents very different amounts of money.

  • Read the contract you trade; do not chart NQ and execute MNQ assuming the flow is identical.
  • Imbalance ratios and minimum-size filters tuned on the E-mini need to be re-derived on the micro.
  • Depth and liquidity on the micro book can be thinner than on the E-mini at the same price.

In Senzoukria

Micros are selected like any other CME contract in the chart workspace "Symbol" field; the guided tour notes that futures use the front contract. Rithmic Direct connects your futures account for ES, NQ and the other CME contracts, subject to the market-data entitlement on that plant, and market data is billed by the provider. In the Replay screen, the "Contract" search lets you find a recorded micro session to replay. The prop-firm rules screen carries a "Maximum contracts" setting and the autopilot a "Max contracts" one; both count contracts of whatever instrument is selected, so a micro cap and an E-mini cap are not equivalent in money.

Common mistakes

  • Assuming micro volume is one tenth of E-mini volume: the two markets have independent participants and the ratio varies by session.
  • Copying footprint settings between MES and ES without re-checking the size per level.
  • Comparing a micro chart with a broker statement quoted in the larger contract's tick value.
  • Forgetting that micro and E-mini expire on the same quarterly cycle, so the roll date affects both.

Frequently asked questions

Is MNQ order flow the same as NQ order flow?
No. MNQ and NQ are two contracts with two order books and two tapes. They track the same Nasdaq-100 index, so their prices move together, but a footprint built on one contains only that contract's executions. If you trade the micro, build your delta and profile on the micro.
Why do traders use micro contracts?
The smaller multiplier lowers the money at risk per tick and per point, which makes position sizing more granular and reduces margin per contract. This is a sizing choice, not a change in the underlying market. Fees per contract are set by the broker and exchange and should be compared against the tick value before assuming micros are cheaper to trade.
Do micros have enough depth for DOM trading?
The micro book is a separate ladder and its displayed liquidity is generally different from the E-mini's. What you see on the DOM for MES is resting size on MES only. Check the ladder on the contract you intend to trade rather than inferring it from the larger book.
