0DTE SPY Options

Whether you're new to zero-days-to-expiration or scaling an existing approach, understanding the fundamentals of 0DTE trading is essential before you trade live capital. This guide covers The SPDR S&P 500 ETF Trust (SPY) is one of the most liquid and heavily traded exchange-traded funds in the world. Trading 0DTE SPY options has become a favorite pastime for retail traders looking for fast, intraday exposure to the broader market.

What Is SPY 0DTE?

SPY 0DTE refers to options on the SPY ETF that expire on the exact day they are traded. These options allow you to speculate on the intraday movement of the S&P 500 without committing massive amounts of capital. Because the options expire at 4:00 PM EST that same day, time decay (theta) is extremely high, and gamma risk is significant.

SPY vs SPX for 0DTE Trading

The debate between SPX 0DTE and SPY 0DTE is ongoing. SPX options are index options—they are cash-settled and have European-style expiration (no early exercise). SPY options, on the other hand, are American-style and physically settled. One SPX contract controls roughly ten times the value of one SPY contract.

Assignment Risk in SPY 0DTE

The biggest danger when trading SPY 0DTE options is assignment risk. Because SPY options are physically settled, if you hold a short option that expires in-the-money (ITM), you will be assigned 100 shares of SPY per contract. This can create massive margin calls and risk over the weekend if you do not have the capital to cover the shares. It is critical to close all SPY 0DTE positions before the closing bell to avoid assignment.

SPY 0DTE Strategies for Beginners

For beginners, selling naked options on 0DTE is heavily discouraged due to unlimited risk. Instead, focus on risk-defined strategies. Selling 0DTE credit spreads allows you to collect premium while strictly capping your maximum loss. Iron Condors are another popular way to play a range-bound market, but they require strict risk management discipline.

Broker Requirements for SPY 0DTE

Most brokers allow you to trade SPY 0DTE if you have Level 2 options approval (the ability to buy calls/puts and sell covered calls/cash-secured puts) or Level 3 (for spreads). Because SPY requires less capital than SPX, it's widely available on retail platforms. If you are looking for the right platform, check out our guide on best brokers for 0DTE.

SPY 0DTE Tax Treatment

Unlike SPX (which benefits from Section 1256 60/40 tax treatment), SPY options are taxed just like regular stock options. Gains on 0DTE trades will be taxed as short-term capital gains at your ordinary income tax rate.
