What is a 0DTE Vertical Spread?

A vertical spread is the fundamental building block of options trading. It involves buying and selling options of the same type (either calls or puts), with the same expiration date, but at different strike prices. Every complex strategy—from Iron Condors to Butterflies—is essentially just a combination of vertical spreads.

When applied to 0DTE (Zero Days to Expiration), vertical spreads are powerful tools for directional trading with strictly defined risk.

The Four Types of Vertical Spreads

Vertical spreads can be executed for a debit (you pay to enter) or a credit (you receive money to enter).

1. Bull Call Spread (Debit)

Used when you are aggressive and strongly bullish.

• Action: Buy an ATM or slightly ITM call, and sell an OTM call (higher strike).
• Goal: The market moves up quickly.
• Max Loss: Net debit paid upfront.
• Max Profit: Strike width minus the debit paid.

2. Bear Put Spread (Debit)

Used when you are aggressive and strongly bearish.

• Action: Buy an ATM or slightly ITM put, and sell an OTM put (lower strike).
• Goal: The market drops quickly.
• Max Loss: Net debit paid upfront.
• Max Profit: Strike width minus the debit paid.

3. Bull Put Spread (Credit)

Used when you are neutral to mildly bullish.

• Action: Sell an OTM put, and buy a further OTM put (lower strike).
• Goal: The market stays above your short strike.
• Max Loss: Width minus credit received.
• Max Profit: Net credit received.

4. Bear Call Spread (Credit)

Used when you are neutral to mildly bearish.

• Action: Sell an OTM call, and buy a further OTM call (higher strike).
• Goal: The market stays below your short strike.
• Max Loss: Width minus credit received.
• Max Profit: Net credit received.

Choosing Between Debit and Credit in 0DTE

The most critical decision in 0DTE vertical spread trading is choosing whether to use a Debit or a Credit spread.

• Use Debit Spreads when you expect a massive directional move early in the day (e.g., following a major earnings gap). Debit spreads suffer heavily from Theta (time) decay. If the market goes nowhere for 4 hours, your debit spread will lose most of its value.
• Use Credit Spreads when the market is choppy or grinding slowly. Credit spreads benefit from Theta decay. If the market goes nowhere for 4 hours, your credit spread will become highly profitable. 0DTE traders overwhelmingly prefer credit spreads because they put time on your side.
