Initial Margin vs Maintenance Margin
The CME sets baseline margins, but brokers and prop firms tend to adjust these numbers depending on volatility.
- Initial margin — upfront capital required to enter
- Maintenance margin — minimum balance you must keep
Prop firms may treat these differently, which ties into your existing article margin policy differences.
How to Size Positions in 6B
The math is straightforward:
- 1 tick = $6.25
- 10 ticks = $62.50
- 20 ticks = $125
- 40 ticks = $250
Most clean intraday moves run 20–40 ticks before pulling back. If a 40-tick stop feels too large for you, you’re trading too big.
