Contract Size Equivalencies
Contract Type | Equivalent in Micros | Examples (Symbols) |
1 Micro | 1 unit | MES, MNQ, M2K, MCL, etc. |
1 Mini | 10 micros | ES, NQ, YM, CL, etc. |
1 Full-Size | 50 micros | e.g., Eurodollar, some bonds |
Position Limits by Account Size
Each account has a maximum position size based on micro equivalents. You may combine micros, minis, and full-size contracts, but the total cannot exceed your tier’s limit.
Account Size | Max Micros | Examples of Allowed Combinations |
$50K | 50 micros | • 50 MES |
$100K | 100 micros | • 100 MES |
$150K | 150 micros | • 150 MES |
Trading Multiple Instruments
You can diversify across multiple instruments (e.g., MES + MNQ + M2K).
All contracts are converted into micro equivalents and count toward your account’s total.
Example: On a $100K account, holding 4 ES minis (40 micros) and 60 MES micros = exactly at the 100-micro limit.
Contract Type Recommendations
New Traders: Stick with micros (MES, MNQ, M2K, etc.) for smaller sizing, more flexibility, and controlled risk.
Experienced Traders: Minis (ES, NQ, YM, etc.) are more capital efficient — lower commissions relative to size.
Full-Size Contracts: Very high notional value; only suitable for highly skilled traders due to their impact on drawdown and risk.
