Definitions
- Tick size — minimum price increment (e.g. NQ 0.25).
- Tick value — dollars gained or lost per tick per 1 contract.
- Point value — dollars per 1.00 full point move per contract (often = tick value ÷ tick size).
- Micro ratio — typically 10 micros ≈ 1 mini for CME equity indices.
Risk per contract at stop =stop_ticks × tick_value
Or with points:stop_points × point_value

Forex note
Forex in PropSize uses pip value per 1.0 standard lot (typically ~$10/pip on many USD-quoted majors; JPY pairs differ). Mini lots (0.1) and micros (0.01) scale linearly. Always confirm your broker’s contract specs and account currency.
Disclaimer on specs
CME and exchange contract specs can be amended. This page is for education and rapid sizing estimates. Cross-check tick size and multiplier on the exchange or your platform before live trading.
