0DTE Options Strategy: A Guide for Traders

0DTE Options Strategy: A Guide for Traders

Options are contracts that give the buyer the right, but not the obligation, to buy or sell an underlying asset at a specified price and time. Options can be used for various purposes, such as hedging, speculation, income generation, or portfolio diversification.

One of the factors that affect the value of an option is time decay. Time decay is the decrease in the option’s price as it approaches its expiration date. The closer the option is to expiration, the faster it loses value due to time decay.

Some traders use a strategy called 0DTE options, which stands for zero days to expiration. This means that they buy or sell options on the same day that they expire. This strategy can be risky, but also potentially profitable, depending on the market conditions and the trader’s skill.

The main advantage of 0DTE options is that they are very cheap compared to longer-term options. This means that traders can use a small amount of capital to gain exposure to a large number of underlying assets. For example, if a stock is trading at $100 and a 0DTE call option with a strike price of $101 costs $0.01, then a trader can buy 100 contracts for $100 and control 10,000 shares of the stock.

The main disadvantage of 0DTE options is that they have a very low probability of success. Most of the time, the options will expire worthless or with minimal value, resulting in a loss for the trader. The trader needs to be very accurate in predicting the direction and magnitude of the price movement of the underlying asset in order to make a profit.

Another challenge of 0DTE options is that they are subject to high volatility and liquidity risk. Volatility is the measure of how much the price of an asset fluctuates over time. Liquidity is the measure of how easily an asset can be bought or sold without affecting its price. High volatility and low liquidity can make it difficult for traders to enter or exit their positions at favorable prices.

Therefore, 0DTE options are not suitable for beginners or risk-averse traders. They require a lot of experience, discipline, and market knowledge to execute successfully. Traders who use this strategy should have a clear trading plan, a strict risk management system, and a well-defined exit strategy.

0DTE options can be an exciting and rewarding way to trade options, but they also come with significant risks and challenges. Traders who are interested in this strategy should do their own research, practice on a demo account, and start with small positions until they gain confidence and skill.

SPX 0DTE Trade Definitions

Credit: The net premium received when selling to open the credit spread.

Credit = (Bidshort - Asklong) * 100

Max. Loss: The risk and maximum loss of the credit spread, incurred if both legs expire in the money.

Max. Loss = (ABS(Strikeshort - Strikelong) * 100) - Credit

R/R: The return-to-risk ratio of the credit spread.

R/R = Credit / Max. Loss

Prob. OTM: The approximate chance of the short leg option expiring out of the money and the full credit being retained.

Prob. OTM = (1 - N(d2short)) * 100

The main factors in the risk-neutral probability calculation for a credit spread are the underlying’s price relative to the short strike, the underlying’s volatility as implied by its near-term options, and the time remaining until expiration.

The drift factor of the formula is determined by the risk-free interest rate, and if applicable, the underlying’s dividend yield.

s = Underlying price.
k = Strike price.
t = Time remaining until expiration.
r = Continuously compounded risk-free interest rate.
q = Continuously compounded dividend yield.
v = Volatility.
N = Cumulative distribution function.

d2 = (LOG(s / (s + ABS(s - k))) + (t * (q - r - ((v ** 2) / 2)))) / (v * SQRT(t))

The model assumes random movement in the underlying without influence from catalytic events occurring before expiration, such as an earnings report or unexpected news. It reflects the expected moneyness at the time of expiration only, and not the probability of the short option moving into the money at least once before expiration and possibly being exercised.

If applicable, the underlying’s next estimated earnings report date is displayed in the row below.


(EV) Expected Value: The average credit retained per trade after factoring in expected losses.

Vertical credit spreads:

EV = (Credit * (1 - N(d2short))) - (Max. Loss * N(d2long)) - (MIN((ABS(Strikeshort - Strikelong) * (1 / (1 + (N(d2short) / N(d2long))))) * 100, Max. Loss) * (N(d2short) - N(d2long)))

Diagonal credit spreads:

EV = (Credit * (1 - N(d2short))) - (Max. Loss * N(d2long)) - ((MIN((ABS(Strikeshort - Strikelong) * (1 / (1 + (N(d2short) / N(d2long))))) * 100, Max. Loss) - expected extrinsic value of long leg at short expiration) * (N(d2short) - N(d2long)))

This interpolation is the sum of the results of a credit spread’s three possible outcomes.

  1. Short leg expires OTM: The full credit is retained.
  2. Both legs expire ITM: The maximum loss is incurred.
  3. Short leg only expires ITM: The price of the underlying at expiration is in between the strikes. A submaximal loss equal to the payout of the short leg is incurred.

    For vertical credit spreads in this situation which aren’t comprised of cash-settled index options, additional losses could occur due to pin risk since the hedging long leg has expired worthless. To mitigate this risk, close positions that are near the money at expiration.

    The expected value for diagonal credit spreads in this situation benefits from the remaining time value of the long leg offsetting the cost of the short leg’s exercise.

A positive expected value indicates a statistical edge and profitability over time, meaning enough credit is collected on each iteration of the trade to offset its potential losses excluding commissions.


(ER) Expected Return: The expected value per trade relative to the capital risked.

ER = (EV / Max. Loss) * 100


(AER) Annualized Expected Return: The expected return with respect to the time remaining until expiration, representing the capital efficiency of the trade.

AER = (((1 + (ER / 100)) ^ (1 / (business days until expiration / 252))) - 1) * 100


(POP) Probability Of Profit: The approximate chance of the underlying price being at least $0.01 away from the break-even price of the credit spread at expiration.

Call credit spreads:

POP = (1 - N(d2breakeven)) * 100

Put credit spreads:

POP = (1 - N(-d2breakeven)) * 100


(BE) Breakeven: The break-even price of the credit spread.

Call credit spreads:

BE = Strikeshort + Net

Put credit spreads:

BE = Strikeshort - Net


Net: The market price of the credit spread.

Net = Bidshort - Asklong


Bid: The bid price of the short leg option.


Ask: The ask price of the long leg option.

(IVP) Implied Volatility Percentile: The percentage of days over the past year when the underlying had a 30-day implied volatility value lower than its current level.


(IVR) Implied Volatility Rank: The underlying’s current 30-day implied volatility relative to its highest and lowest levels over the past year.


(IVSP) Implied Volatility Skew Percentile: The percentage of days over the past six calendar months when the underlying had a 30-day implied volatility skew lower than its current level. This is a comparative measure of investors’ directional sentiment and is derived from the underlying’s ratio of OTM and ITM implied volatility.

The sentiment is displayed in the row below, with percentiles 0-39, 40-59, and 60-99 representing a bullish, neutral, and bearish outlook respectively.

To the right of the sentiment is the time since the underlying’s options were scanned, representing the age of the data. Hover to reveal the exact time of the last update.

Mini-SPX Index Options (XSP)

The Cboe Mini-SPX option contract, known by its symbol XSP, is an index option product designed to track the underlying S&P 500 Index. At 1/10 the size of the standard SPX options contract, XSP provides greater flexibility for new index options traders or traders managing an individual portfolio.

XSP Weekly Options

Whether it’s trading around specific events, such as earnings announcements or economic data reports, or executing overwriting or spread-trading strategies, Cboe XSP weekly options allow traders the granularity to more closely tailor their trades to meet their needs. And for traders executing premium collection strategies, XSP weekly options provide the opportunity to collect premium 52 times per year rather than 12.

XSP weekly options are offered with Monday, Wednesday, and Friday settlements. For Friday settlements, options contract expirations occur on non-standard Friday expirations throughout the year. Similarly, Monday and Wednesday XSP Weeklys options settlements may expire on any Monday or Wednesday of the month, other than a Monday or Wednesday that coincides with an end-of-month expiration date.

XSP Monday, Wednesday and Friday Weeklys options are typically listed on Friday, Tuesday and Thursday, respectively and will expire on their expiration date. If a standard or EOM options contract settlement exists in a week that coincides with a typical Weekly expiration date, a Weekly expiration will not exist on that expiration day. (The term Weeklys refers to the fact that the contracts are listed every week, not that they are a seven-day contract). Settlement processes for XSP weeklys are the same as their standard options counterparts (index, ETF, etc.).

Trading XSP

XSP options trade on Cboe’s Hybrid Trading System, which provides investors with the combined advantages of electronic trading and an open-outcry market on a single platform. XSP options also trade on the EDGX exchange.

SPX 0DTE strategy

What is SPX 0DTE strategy?

SPX weekly options that expire on every Monday, Wednesday and Friday we trade them on the day it expires. So, there is no overnight risk. Usually we open a credit spread when the market open around 9:30 A.M EST, and we close the trade before market close same day around 4:00 P.M EST. That is why it is called 0DTE, AKA same day option trade.

Why 0DTE strategy?

1. Can Profit if SPX increase, decrease, or doesn’t move at all. (High probability of making money)

2. Limited loss potential. Never worry about “blowing up” when the market makes a huge move (assuming appropriate position size)

3. Very simple strategy. The two primary credit spread strategies only have two components.

4. Consistent daily/weekly income. (why i started trading this strategy personally 🙂 )

What is SPX?

SPX, or the Standard & Poor’s 500 Index, is a stock index based on the 500 largest companies with shares listed for trading on the NYSE or NASDAQ. The term “largest” refers to each firm’s market capitalization or its stock price multiplied by the number of shares it has outstanding.

The SPX itself may not trade, but both futures contracts and options certainly do.

Why SPX?

1. SPX Options expire on every Monday, Wednesday and Friday.

2. SPX pays no Dividend.

3. SPX Cash Settled when the market closes at 4:00 P.M EST.

No risk of early assignment and loss of dividends, no portfolio disruption on assignment.

What is a Credit Spread?

A credit spread where we sell an option at one strike and simultaneously buy an option at another. The way we use this in the SPX Spread Trader is to use a 5 pt spread between the 2 strike prices. So if we are selling a 3100 call we are purchasing a 3105 call at the same time. By entering these two trades as a single credit spread order, there is only a single commission cost. The difference in prices between these two options provides a net credit to your account. The beauty of this approach, is that there is no price movement in the SPX required to be profitable. SPX can go flat or have little movement at all, and our trade will still be profitable. All we need is for the SPX to close below 3100 (in this example), and both options will expire worthless and we retain the credit.

SELL TO OPEN -1 SPX NOV 15 2019 3100 CALL

BUY TO OPEN +1 SPX NOV 15 2019 3105 CALL

Net credit of $0.60. max loss:$4.40

in this example, we are investing $500 to open a bear call spread, receiving $60, and risking $440. as long as SPX stays below 3100 at 4:00p.m. EST, we will keep $60.

Most of the time, we don’t wait till market close. We close the trade at 50-60% profit target, and 2-2.5X credit stop loss.

in this example, we would close it for $0.20. So, we would make 0.60-0.20=$0.40 profit. OR, we would stopped out at $1.50 which is at 1.50-0.60=$90 loss.
