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.

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.
