Debit Spread

A defined-risk options strategy that profits from directional movement — SPXXL's primary recommended structure for most session types.

A debit spread (also called a vertical debit spread) involves buying one option and selling another at a different strike in the same expiration. You pay a net debit to enter the position, and your maximum risk is limited to what you paid.

Call Debit Spread (bullish):

  • Buy a lower-strike call, sell a higher-strike call
  • Profits when SPX moves up above the lower strike
  • Max profit = strike width - debit paid
  • Max loss = debit paid

Put Debit Spread (bearish):

  • Buy a higher-strike put, sell a lower-strike put
  • Profits when SPX moves down below the higher strike
  • Max profit = strike width - debit paid
  • Max loss = debit paid

Why SPXXL recommends debit spreads for 0DTE:

  • Defined risk — you can never lose more than the debit paid
  • Capital efficient — $200-500 per spread vs. thousands for naked options
  • Directional profit — captures the move identified by session classification
  • Theta-resistant — when deep enough ITM, theta decay is your ally
  • No margin surprises — no possibility of assignment risk beyond your defined risk

SPXXL's structure recommendation engine suggests specific spread configurations based on the session classification, confidence level, and current premium pricing. Higher confidence Trend Day classifications get tighter, more aggressive debit spreads. Lower confidence or Balanced Day classifications may get wider structures or no recommendation at all.
