The ongoing buzz in retail traders leveraging short-term price swings with zero-days-to-expiration (0DTE) options is gradually making its way into the market. For those interested, understanding the 0DTE options strategy, the way it works, the risks involved, and the need for quick decisions is vital. While potentially lucrative, 0DTE options demand thorough knowledge, prompt action, and risk management to navigate successfully.
Zero Days to Expiration (0DTE) options are contracts that expire on the same trading day they are initiated. These options are typically traded during the final hours of expiry and are available for various indices and underlying assets. Since they have no remaining time value by the end of the session, their pricing reacts sharply to market movements, often influenced by volatility and directional shifts. Traders dealing in 0DTE options aim to capture rapid, intraday price changes. Due to the limited timeframe, these contracts are highly sensitive to underlying asset fluctuations and tend to experience accelerated premium decay. 0DTE options are used in both directional and non-directional strategies, but they involve considerable risk due to their time-sensitive nature. They are usually selected by market participants seeking exposure to short-term movements without overnight risk.
The options market has seen a surge in activity from retail traders seeking to capitalize on short-term price swings and market volatility. The relatively new phenomenon, zero-days-to-expiration (0DTE), has made quite an entry into the mainstream and has become a popular strategy for collecting premiums. If you too are interested in starting or continuing your trading journey with 0DTE options, you are at the right place. Before you invest your hard-earned money in the market, make sure you know the tricks of the trade.
You would know by now that options are financial tools that are traded in the derivative market. They give the buyer the right, however, not the obligation, to buy or sell an asset (like a stock) at a set price within a certain period. The buyer can choose to use this right at any time before the option expires.
Zero-days-to-expiry options, also called 0DTE options, are contracts that expire and become void on the same day they are traded. Simply put, traders need to get in and out of the options on the day they are scheduled to expire. Also called same-day options, 0DTE options are indeed a unique tool. They let traders profit from short-term price changes in the market.
Unlike traditional options that last weeks or months, 0DTE options are meant for traders who want quick results, as they expire on the same day they are bought.
A Zero Days to Expiration (0DTE) options strategy focuses on intraday market opportunities by using options contracts set to expire the same day. Traders typically initiate positions based on market direction, volatility, or key support and resistance levels. Common strategies include selling options to benefit from rapid time decay or buying options to speculate on a strong directional move. The positions are closely monitored due to the extremely limited lifespan of the contracts. Most 0DTE strategies require precise entry and exit points, tight risk management, and constant adjustments. Since time value erodes quickly, any delay in decision-making may significantly impact outcomes. These strategies often aim to capitalise on market events such as economic data releases or index rebalancing but carry a higher risk due to limited recovery time in case of adverse movement.
The way zero day options work is what separates them from traditional/ regular options. Their short lifespan makes them time-sensitive. The ‘0’ or the ‘zero’ in 0DTE means it's the last/ only day to use the option. Typically, traders have some time to wait and see if the asset's price has panned out as per their expectations. However, when it comes to the 0DTE options, there's no waiting—decisions must be made quickly because, here, the clock is ticking.
The profitability of 0DTE options depends on several factors including timing, volatility, and execution strategy. While these contracts provide opportunities to benefit from sharp intraday movements or premium decay, they also carry a high risk of complete loss. Since 0DTE options have no time buffer, even minor market reversals may impact outcomes significantly. Traders may deploy spread strategies, scalping, or selling options to generate potential gains, but success relies heavily on precision and discipline. Without appropriate risk controls, losses can accumulate quickly. Additionally, transaction costs and slippage may reduce net profitability. Therefore, profitability in 0DTE options is variable and contingent upon strategy selection, market conditions, and individual execution skills, rather than any inherent advantage in the instrument itself.
When discussing trading strategies, like most others, 0DTE options strategy also has mixed reviews. Often called a lotto trade, many investors take it as an easy way to make money. Popular for premium collection, time decay often benefits options sellers. Capital is tied up only briefly, with trades entered and closed on the same day. The leverage involved allows investors to take multiple positions, enhancing potential gains.
Premium decay refers to the reduction in an option’s value as it approaches expiration. For 0DTE options, this decay occurs rapidly throughout the trading day since there is no time left beyond market close. As time value diminishes, especially in out-of-the-money options, their premiums can erode quickly. This characteristic is often used by traders who sell options early in the day and aim to profit as the premium drops due to time decay. However, the same factor may work against buyers, as an option’s value may fall even if the underlying moves marginally in their favour. Premium decay is most pronounced in the final hours before expiry and is a critical factor to consider when selecting positions in 0DTE trading.
0DTE options are not typically suited for beginners due to their time-sensitive nature and rapid price changes. Trading these contracts requires strong market understanding, precise technical analysis, and disciplined risk management. Since the window for making decisions is extremely short, traders must react quickly to evolving market trends without hesitation. Small mistakes in timing, order execution, or market interpretation may lead to disproportionately large impacts on returns. Moreover, intraday volatility can amplify risks. Understanding option Greeks such as theta and delta is essential to managing exposures effectively. Without adequate experience and preparation, participating in 0DTE strategies may expose traders to sudden and unexpected losses. Therefore, proficiency in both market reading and options trading mechanics is considered essential.

DTE stands for “Days to Expiration” in options trading. It indicates the number of calendar days remaining until an options contract expires. DTE is a key variable in determining the time value component of an option’s premium. Contracts with higher DTE generally carry more time value and tend to react less sharply to short-term price fluctuations. As DTE decreases, options become more sensitive to market movements, and premium decay accelerates, especially in the final few days. Traders use DTE to select contracts that align with their strategy—whether short-term or long-term. In the case of 0DTE options, the DTE is exactly zero, meaning the option will expire at the end of the trading session.
Zero Days to Expiration (0DTE) options expire on the same day they are traded. In India, index options such as those on Nifty and Bank Nifty expire at the end of their respective sessions, typically at 3:30 PM IST on the expiry day. If initiated in the morning, the trader has only a few hours to close or manage the position before settlement. These contracts do not carry any overnight value and must be squared off or allowed to expire by the end of the day. Due to their intraday expiry, 0DTE options are often used by traders looking for short-duration opportunities or wishing to avoid holding positions overnight.
If an options contract is not exercised before it expires, it is settled automatically by the exchange based on its moneyness at expiry. In India, index options are cash-settled. In-the-money (ITM) options may be settled for the difference between strike and closing prices, while out-of-the-money (OTM) options expire worthless. No manual exercise is required by the holder. However, if the position is left open, any applicable charges, taxes, or margin requirements are applied at settlement. Hence, it is important to monitor positions and understand potential obligations before the market closes. Non-exercised contracts do not result in delivery but are resolved through final settlement prices determined by the exchange.
For many investors, budding and seasoned alike, 0DTE options may appear to be an appealing choice. And while there is no denying that they can be high-paying, such options trading strategies come with their own set of risks and complications. It is best recommended that you keep the following points in mind when you opt for zero day options.

However, as an investor, you need to bear in mind that a no-risk, high-return option doesn’t really exist.
