What Is 0DTE Options Trading? A Complete Beginner Guide
Zero days to expiration options are the fastest-moving, highest-risk contracts available to retail traders. In a single session, a well-timed 0DTE trade can double or triple in value — or expire completely worthless. Here is everything you need to understand before you trade one.
What Does 0DTE Mean?
0DTE stands for "zero days to expiration." An options contract is a financial instrument that gives the buyer the right — but not the obligation — to buy or sell 100 shares of a stock at a specific price (called the strike price) before a set date (the expiration date). A 0DTE contract expires at the end of the current trading day — 4:00 PM Eastern Time for most stocks and ETFs.
Because the contract expires that same day, you have a very short window to be right about the direction of the stock. If the stock does not move as you expected before the closing bell, your contract expires worthless and you lose the entire premium you paid.
Why Do Traders Use 0DTE Options?
0DTE options have exploded in popularity over the last few years, now accounting for roughly 50% of total options volume on major indexes like SPY and QQQ on any given day. The reasons are straightforward:
Low cost per trade
Because there is almost no time left in the contract, 0DTE premiums are cheap — often $1.00–$5.00 per share, or $100–$500 per contract. This keeps the initial capital requirement small.
High leverage
A small move in the underlying stock can produce a large percentage gain in the option. A 0.5% move in SPY can produce a 50–200% gain in an ATM 0DTE option.
No overnight risk
The position opens and closes the same day. You are never exposed to after-hours news, earnings surprises, or gap-down opens the next morning.
Daily opportunities
Major indexes like SPY and QQQ offer 0DTE contracts every trading day. There is always a new setup available if you are patient enough to wait for one.
The Risks You Must Understand
0DTE options are not a shortcut to consistent profits. They are highly speculative instruments with a very real chance of total loss on every trade. Before you place your first 0DTE trade, you must understand and accept the following:
⚠️ Core Risks
Theta decay is brutal: Options lose value every minute due to time decay (theta). On a 0DTE contract, this decay accelerates exponentially as the day goes on. By 3:00 PM ET, a contract that is not in-the-money can lose value extremely rapidly even if the stock barely moves against you.
You can lose 100% of your investment: If your contract expires out-of-the-money, it is worth exactly zero. There is no partial recovery, no averaging down — the premium you paid is gone.
Spreads cost you money: The bid-ask spread on 0DTE options can be significant. If you buy at the ask and sell at the bid, you may start each trade at a 5–15% disadvantage before the stock moves at all.
Volatility can crush you: A sudden spike in implied volatility (IV) before your entry can make contracts much more expensive than normal. If IV collapses after you buy, your contract can lose value even if the stock moves in your favor.
CALL vs PUT — Which Direction?
Every 0DTE trade is either a CALL (betting the stock goes up) or a PUT (betting the stock goes down). Choosing the right direction is the most important decision you make on each trade.
CALL — Bullish
Buy a CALL when you believe the stock will rise. Your CALL increases in value as the stock climbs above your strike price. Maximum profit is theoretically unlimited. Maximum loss is the premium you paid.
PUT — Bearish
Buy a PUT when you believe the stock will fall. Your PUT increases in value as the stock drops below your strike price. Maximum loss is the premium you paid.
Hood Option's Market Tracker makes this decision for you algorithmically — it analyzes VWAP, MACD, Bollinger Bands, and 13 chart patterns to determine the current directional bias and gives you a CALL, PUT, or NEUTRAL signal with a confidence percentage.
The Best Times to Trade 0DTE Options
Not all hours of the trading day are equally suitable for 0DTE trades. Here is the framework most experienced 0DTE traders follow:
9:30 – 9:45 AM ET
🚫 Avoid
The opening 15 minutes are chaotic. Spreads are wide, moves are erratic, and the market is still finding its footing after overnight news. Most experienced traders do not trade in the first 15 minutes.
9:45 – 11:30 AM ET
✅ Prime window
The best intraday window for 0DTE trades. Volume is high, trends are establishing, and VWAP signals are reliable. This is when Hood Option signals carry the most weight.
11:30 AM – 2:00 PM ET
⚠️ Slow period
Lunchtime lull. Volume drops, price action becomes choppy and range-bound. Signals are less reliable. Many traders stay flat during this window.
2:00 – 3:30 PM ET
✅ Second window
Volume picks up again as institutional traders position for the close. Good setups are available but you must exit before 3:30.
3:30 – 4:00 PM ET
🚫 Exit only
Theta decay is at its most aggressive in the final 30 minutes. Never hold a 0DTE contract into this window unless it is deep in-the-money. Always be out by 3:30 PM.
Choosing the Right Strike — Always ATM
For 0DTE trading, the standard approach is to always buy the at-the-money (ATM) strike — the strike price closest to the current price of the stock. Here is why:
- • In-the-money (ITM) strikes are more expensive and offer lower leverage. You pay more premium for the intrinsic value, which reduces your potential percentage gain.
- • Out-of-the-money (OTM) strikes are cheap but require a large stock move to become profitable. On a 0DTE, there usually is not enough time for that move to happen.
- • ATM strikes offer the best balance — affordable premium, high delta (sensitivity to stock moves), and a realistic chance of landing in-the-money by expiry.
Hood Option's Trade Search and Market Tracker always target the ATM strike and display the current premium, so you always know your exact contract cost before you place the trade.
A Simple Framework for Your First 0DTE Trade
Wait for a Hood Option signal with 80%+ confidence and a PRIME designation.
Check the time — only enter between 9:45 AM and 11:30 AM or 2:00 PM and 3:30 PM ET.
Open your brokerage app, search the ticker, tap Trade → Options.
Select today's expiration date (labeled "Today" or with the current date).
Choose CALL or PUT to match the Hood Option signal direction.
Select the ATM strike — the one closest to the current stock price.
Set quantity to 1 contract. Review the estimated cost.
Use a limit order between the bid and ask price — never use market orders on options.
After entry, set a mental stop at −50% of your premium. If the contract loses half its value, exit.
Take profit when the contract reaches +20% of your entry cost. Do not get greedy.
Final Thoughts
0DTE options are not a get-rich-quick scheme. They are a precision tool that rewards discipline, patience, and strict risk management. The traders who succeed with them are the ones who wait for high-quality setups, trade small, cut losses quickly, and never hold a contract past 3:30 PM.
Hood Option is designed to give you the best possible information to make that judgment — live signals, confidence scores, entry prices, profit targets, and estimated time to target. The rest is up to you.
