MNQ Trading Journal
MNQ moves $0.50 a tick — a tenth of full-size NQ's $5. That low per-tick cost is why it's the default entry point for new futures and prop-firm traders, but it hides a real failure mode: because each tick feels small, it's easy to size up to 15, 20, or 30+ contracts to make a trade feel meaningful, quietly recreating NQ- or ES-level dollar risk without ever seeing an NQ-sized number on the ticket.
The contract math, in real dollars
A 10-point MNQ move is 40 ticks — $20 at one contract. At 25 contracts, the same 10-point move is $500, which is real money moving on a "micro" trade. Fillbook logs every MNQ fill against its actual $0.50 tick value, so your R-multiple and position sizing reflect the dollar risk you actually took, not the contract count on the ticket.
Sizing creep is the pattern to watch, not the trade itself
The behavioral risk with MNQ usually isn't one bad trade — it's contract count drifting upward over weeks as $0.50 ticks stop feeling like real risk. Tracking size per trade alongside R-multiple in one place makes that drift visible before it shows up as a drawdown.
Overtrading is cheaper to fall into on MNQ
Low per-trade cost also lowers the bar for taking a trade you shouldn't have. Fillbook's rule-based overtrading and revenge-trading detection runs on your logged MNQ history the same way it does for any instrument — flagging the pattern directly rather than leaving it to a gut feeling.
Prop-firm accounts and MNQ
Lower margin requirements make MNQ a common instrument inside prop-firm evaluations and funded accounts. The dollar math still scales with contract count, so trailing drawdown and daily-loss tracking matter exactly as much as they do at full size — see the prop-firm trading journal page for the account-rule side.
Frequently asked questions
$0.50 per tick (0.25 index points), and $2 per full point — exactly a tenth of NQ's $5 tick / $20 point, since MNQ is sized at 1/10th of a standard E-mini Nasdaq-100 contract.
The low per-tick cost is genuinely useful for learning execution with less dollar risk per contract — the tradeoff is that it's easy to offset that low cost by trading more contracts than you would on NQ, which puts you back at similar dollar risk without it feeling that way.
Yes — P&L, R-multiple, and position sizing are all calculated per contract using MNQ's real tick value, whether trades are imported via CSV or synced automatically from a supported platform.
