What one MYM contract is worth
The Micro E-mini Dow trades on CBOT in increments of 1. Because its point multiplier is $0.50, one tick is worth $0.50 and a full point is worth $0.50 — per contract, in both directions. Multiply by your contract count for the position.
The number that catches people out is notional value: price × $0.50, which is the exposure one contract actually carries, not the margin you posted to open it. Change the price above to see it for the level you're trading.
MYM vs YM
MYM is the micro version of YM (E-mini Dow), at one tenth the size — $0.50 per point against $5.00. Same index, same hours, same tick size; 10× less money per tick.
What an MYM round turn costs
CBOT charges $0.35 exchange and $0.19 clearing per side, plus $0.02 NFA — so $1.12 per round turn, per contract, before your broker's commission. These rates are the same at every broker, because the venue charges them, not the broker — and most brokers' fee column doesn't include them. On MYM that's 2.2 ticks of cost on every trade.
Who trades MYM and when
Same quarterly cycle as YM. Carries the lowest dollar-per-point of any micro index product, which means it takes a larger point move to match an MES or MNQ trade's dollar swing — a plus for very small accounts, but plan on needing more ticks for the same P&L target.
Sizing an MYM position
Contract value is only half the question. How many MYM contracts you should trade depends on your account size and stop distance — the position size calculator works that out, and the expectancy calculator tells you whether the resulting trades pay over time.
