0DTE Margin Requirements

How Margin Works for 0DTE

Margin for options is different from stock margin. For defined-risk strategies (spreads), the margin is simply the width of the spread minus the premium received.

Strategy Margin Requirements

Credit Spread (5-wide on SPX)

• Margin: Width of spread - credit received
• Example: 5-point spread, $1.50 credit = $350 margin per contract
• Actual risk: $350 per contract

Iron Condor (5-wide wings)

• Margin: Width of one wing - net credit
• Example: 5-point wings, $2.00 credit = $300 margin per contract
• Actual risk: $300 per contract

Straddle/Strangle (naked)

• Margin: Significant — 20-30% of underlying notional value
• This is why defined-risk alternatives are preferred

Pattern Day Trader (PDT) Rule

If you make 4+ day trades in 5 business days with a margin account under $25,000, you’re flagged as a PDT. Solutions:

• Use a cash account (no margin, but no PDT rule)
• Use a margin account with $25,000+
• Use a prop trading account

Key Takeaway

Start with defined-risk strategies in a cash account to avoid PDT issues. As your account grows and skills improve, you can explore more advanced strategies.
