Guide · E-mini vs micro futures
E-mini vs micro futures is the first sizing choice every new trader faces. The most common way beginners fail a prop firm evaluation is not a bad strategy. It is trading a contract that is too big for the account and their experience.
The basics
Both are futures contracts on the same index. The E-mini S&P 500 (ES) and its Micro counterpart (MES) both track the S&P 500. The difference is size: one Micro is one tenth of one E-mini. Same market, same price action, one tenth the dollar risk per point.
Side by side
| E-mini | Micro | |
|---|---|---|
| Contract size | $50 × index (ES) | $5 × index (MES), one tenth |
| Move per point | Larger swings, larger P&L | Smaller swings, smaller P&L |
| Best for | Funded accounts with a track record | Learning execution and first evaluations |
| Drawdown risk | Hits daily loss limits faster | Easier to stay inside the rules |
Sizing
Micros let newer traders practice order entry, stops and position management without one bad trade wiping out a real chunk of an account.
On a $50K evaluation with a $1,000 daily loss limit, a few E-minis moving against you can end it in minutes. Micros give you room to adjust.
Move up only after a record of consistent, rules-following trades, not after one good week.
