How to size a trade
Decide how much of your account you're willing to lose if the stop is hit (most traders use 0.5% to 2%). Divide that by what one contract loses at your stop. Round down, never up.
Example: $10,000 account, 1% risk = $100. A 20-point stop on MNQ costs $40 per contract, so you can trade 2 MNQ ($80 risk). On NQ the same stop costs $400, so NQ is too big for that account.
Quick answers
How do I calculate position size?
Divide the dollars you're willing to lose (account × risk %) by what one contract or lot loses at your stop. Round down.
How much is one point on NQ, MNQ, ES and MES?
NQ is $20 per point, MNQ $2, ES $50, MES $5. YM is $5 per point and MYM $0.50.
What risk per trade should I use?
Many traders risk 0.5% to 2% of their account per trade, so a losing streak doesn't wipe them out.
