Position Size for Futures (ES / MES)

Position sizing determines how many contracts you trade. It should always be based on risk—not guesswork.

The Goal

Your position size should match your risk per trade and your stop loss distance.

Example

If you have a $10,000 account and risk 1%:

• Risk per trade = $100

If your stop loss is 10 points on ES:

• 1 ES contract = $50 per point
• 10 points = $500 risk

That means:

• 1 ES contract = too large
• 1 MES contract = more appropriate

Why This Matters

Trading too large leads to unnecessary losses and emotional decisions. Correct position sizing keeps your risk consistent.

ES vs MES

• ES = $50 per point
• MES = $5 per point

Smaller accounts should use MES to control risk more precisely.

Bottom Line

Position size is not about maximizing profit. It is about controlling risk so you can stay consistent over time.
