XSP Options (Mini-SPX): How the Smaller S&P 500 Index Option Works and What Day Traders Should Know in 2026

XSP options are index options on the Mini-SPX Index, which Cboe calculates at one tenth the value of the S&P 500. They work like the standard S&P 500 index options known by the ticker SPX, with the same cash settlement and the same European exercise style, but each contract is one tenth the size. Ten XSP contracts carry roughly the same exposure as one SPX contract.

That size difference sounds like a footnote. For a day trader it is the whole point. The size of one contract decides how much a one-point move in the index is worth to you, and that number decides whether a normal wiggle in the market is a small cost or a big piece of your daily loss limit. A product that is too big for your account forces you into all-or-nothing sizing. A smaller one lets you size in steps.

In this guide we'll cover what XSP options are, how they differ from SPX and SPY options, why contract size matters so much for risk per point, how a day trader can use that granularity, and what changes inside a simulated funded options account, including the honest point that XSP is not on TradeFundrr's published list of underlyings, so you need to confirm what your platform offers.

Key Takeaways

  • Think of XSP as SPX divided by ten. The Mini-SPX Index is one tenth of the S&P 500, and each XSP contract has a $100 multiplier, so one SPX equals ten XSP.
  • Measure risk in dollars per index point. The same chart setup can be a $50 idea or a $500 idea depending on which contract you choose.
  • Use small contracts to size in steps, not to trade more. Granularity is a risk tool. It stops being one the moment you use it to add positions.
  • Know which mechanics are live-only. Cash settlement and European exercise describe how a real exchange settles real contracts. A simulated account handles expiration through the platform.
  • Confirm the underlying before you plan around it. TradeFundrr's options pages list SPX, SPY, QQQ and IWM. XSP is not on that list, so check your own platform.

What are XSP (Mini-SPX) options?

XSP options are cash-settled, European-style options on the Mini-SPX Index, listed by Cboe. The index is based on one tenth of the S&P 500, so if the S&P 500 is at 6,000, the Mini-SPX Index is at 600. Each contract uses a $100 multiplier, the same multiplier SPX uses, which is why the contract ends up one tenth the size.

The one-tenth relationship

Cboe's own XSP product page describes the product as offering exposure to the S&P 500 at one tenth the size of standard SPX contracts, and its comparison calculator states the relationship plainly: one SPX equals ten XSP. The XSP contract specifications list the multiplier as 100 and the underlying as the Mini-SPX Index, based on one tenth the value of the S&P 500.

Put those together and the math is simple. Notional value is the index level times the multiplier. Illustrative example: with the S&P 500 at 6,000, one SPX contract controls a notional value of 6,000 times $100, or $600,000. One XSP contract controls 600 times $100, or $60,000. Same market, same direction, one tenth the exposure.

Cash settled and European style

XSP shares the two features that separate index options from options on stocks and ETFs. Positions settle to cash at expiration, with no shares delivered or received. And the options can only be exercised at expiration, which Cboe describes as eliminating early assignment risk. If you want the full background on those two ideas, our guide to index options vs equity options walks through settlement and exercise style in detail. This article focuses on what is specific to XSP: its size.

Expirations and hours

Cboe lists standard, weekly and end-of-month XSP expirations, along with zero days to expiration (0DTE) contracts, and publishes regular, curb and global trading hours in its specifications. Two cautions: exchange hours are not the hours your account allows, and very short-dated options move fast whatever their size.

How XSP compares with SPX and SPY options

XSP sits between two products most S&P 500 traders already know. SPX is the full-size index option. SPY options are options on an exchange-traded fund that tracks the S&P 500. XSP has the structure of SPX and a size closer to what SPY traders are used to. The table below lines up the differences that matter for a day trader.

XSP vs SPX: same structure, different size

The only practical difference between XSP and SPX for most traders is size. That makes XSP easy to reason about if you already understand SPX. Every strike, every premium and every dollar of profit or loss is, roughly, one tenth of the SPX equivalent. If a strategy is too large in SPX, the XSP version of the same idea is the same trade at a scale that might fit.

The honest trade-off is liquidity. XSP generally trades less than SPX, so the bid-ask spread can be wider relative to the premium. On a small premium, a few cents of spread is a real share of the trade, paid on every entry and exit.

XSP vs SPY: similar size, different mechanics

SPY options are already small, which is why so many traders use them. The difference is mechanical. SPY options are options on shares, so in a live account they settle by delivering shares, and because they are American style, a short SPY option can be assigned before expiration. XSP avoids both because it is a cash-settled index product. That is the main reason Cboe markets XSP to traders who like the SPY size but not the SPY settlement mechanics.

Why contract size changes your risk per point

Contract size changes how many dollars each index point is worth to you, and that is the number your loss limits actually care about. Two traders can read the same chart, take the same setup and be stopped at the same level, and one can lose ten times what the other loses, purely because of the contract they chose.

Dollars per point, worked through

An option's delta tells you roughly how much its price moves for a one-point move in the underlying. Illustrative example: take an at-the-money call with a delta of about 0.50. If the S&P 500 moves 10 points, the SPX option's price moves about 5 points, and at a $100 multiplier that is about $500 per contract. On XSP, the same 10-point S&P move is a 1-point move in the Mini-SPX Index, so the option moves about 0.5 points, or about $50 per contract.

Delta changes as price moves and as time passes, so these are approximations, not promises. But the ratio holds: the XSP version of a trade carries about one tenth of the dollar sensitivity of the SPX version. The multiplier is what turns a point move in the option into dollars.

Why the daily loss limit makes this urgent

A daily loss limit is a fixed number of dollars. Your stop, on the other hand, is set in index points by what the chart is doing. Contract size is the bridge between the two. Illustrative example: if your setup needs a 20-point stop on the S&P 500 and you trade one 0.50 delta SPX option, that stop is worth about $1,000. On an account with a $1,000 daily loss limit, a single normal stop-out would use the whole day. The same setup in one XSP contract risks about $100, a tenth of the limit.

That is the difference between a trade you can take several times while you work on a setup and a trade that ends your session the first time it fails. Many traders who blow through a daily limit were not reckless in their analysis. Their contract was too big for their budget.

Small does not mean safe

A smaller contract is not a safer product. An XSP option can still lose its entire premium, and short-dated options can lose value fast. What a smaller contract gives you is control over how much of your budget one idea uses. As Investor.gov notes in its definition of day trading, it is extremely risky and can produce substantial losses in a very short time.

How a day trader can use XSP-style granularity

The value of a small contract is granularity: the ability to size in steps that match your risk budget instead of choosing between all or nothing. Used well, it makes your sizing more precise. Used badly, it just gives you more ways to add exposure on impulse.

Sizing in steps

With a full-size contract, you may only have two choices: one contract or none. With a contract one tenth the size, you can trade one, three or five, and each step is a meaningful but modest change in risk. That lets you match position size to the quality of the setup and the distance to your stop, which is how professional sizing is supposed to work. Our guide to options position sizing covers the general method. XSP is simply a product that makes the method easier to apply on the S&P 500.

Scaling out without guessing

Granularity also helps on the way out. With three small contracts you can take one off at each target, all according to a plan. With a single large contract, every exit is all at once.

The trap: using small contracts to trade more

Here is the damaging admission. The same feature that makes XSP useful makes it easy to misuse. When each contract feels small, it is tempting to add one more, then another, and before long you hold the same exposure as a full-size contract without having decided to. Ten XSP contracts are one SPX contract. Granularity only helps if your maximum size is set before the session starts and you stick to it.

Before you trade an S&P 500 option: a sizing check
  • I know the dollar value of a one-point index move for this exact contract.
  • My stop is set in index points from the chart, not from how much I want to risk.
  • My position size comes from dividing my risk budget by the dollars at risk to that stop.
  • The worst case on this trade is a small fraction of today's loss limit, not most of it.
  • I have a written maximum number of contracts for the session.
  • I have checked the bid-ask spread and accept it as a real cost on entry and exit.
  • I have confirmed this underlying is offered on my platform before planning around it.
  • I know how my account handles a position that is still open near expiration.

A worked session

Illustrative example: a trader has a personal daily stop of $400, well inside a $1,000 account limit. Their setup on the S&P 500 needs a 15-point stop. Using a 0.50 delta option, an SPX contract would risk about $750 on that stop, which is almost double their personal stop. One XSP-sized contract risks about $75, so they can take up to five and stay inside $400, or take three and leave room for a second attempt later. The analysis did not change. The sizing decision did.

The same reasoning applies to any S&P 500 product your platform lists. If XSP is not available to you, the point is not lost. You can apply the same dollars-per-point arithmetic to SPY options or to SPX itself, and if the smallest available contract is still too big for your budget, that is useful information too. It means the trade is not the right size for your account, whatever the chart says.

Want to practice index option sizing with published limits? Read the options Pre-Prop account rules: $25,000 in simulated buying power, a $1,000 daily loss limit that pauses the session, and SPX, SPY, QQQ and IWM among the listed underlyings.

XSP and index options in a TradeFundrr funded account

TradeFundrr's options accounts are simulated, and the underlyings you can trade are set by the platform. The published options pages list index options including SPX, plus ETF options on SPY, QQQ and IWM, along with single names. XSP is not on that published list, so before you build a plan around it, confirm in your own platform whether it is offered.

What the published rules say

On the options Pre-Prop evaluation, you trade with $25,000 in simulated buying power. The daily loss limit is $1,000, and reaching it pauses trading for the session; the limit resets the next trading day. The maximum drawdown is $3,000, trailing your highest end-of-day balance, and reaching it closes the account. To pass, you need five profitable days of at least $250 net each, with no time limit, and the days do not need to be consecutive. Trading is manual and intraday only, each trade must be held for at least 15 seconds, and trading hours are Monday through Friday, 9:30 AM to 3:55 PM ET.

Position limits also apply. The cap differs by program and account size, so confirm the current number in your own account terms rather than relying on a figure from an article. Whatever the cap, the sizing logic above still applies: the right number of contracts comes from your risk budget, not from the maximum the account allows.

Live-only mechanics, stated honestly

Cash settlement and European exercise describe how a real exchange settles real contracts. In a live brokerage account, an XSP or SPX option that finishes in the money settles to cash, while a short SPY option could be assigned before expiration and leave you holding or owing shares. In a TradeFundrr simulated account, none of that happens, because no real trade is executed. There is no real counterparty to exercise against you and no shares are delivered.

What matters in the simulated account is how the platform handles positions as the trading day ends, and since the account is intraday only and trading stops at 3:55 PM ET, your plan should be to close positions yourself before then. We still think it is worth learning the live mechanics. Knowing why index options cannot be assigned early, and why SPY options can, is a live-ready skill that will matter the day you trade any options in a personal account. Our guide to assignment risk for funded options covers that side in more depth.

The skill carries over

Whether you trade SPX, SPY or, where it is listed, XSP, the habit being tested is the same: knowing how many dollars each point is worth before you enter, and sizing so one stop-out is a small, planned cost. The five qualifying days come from controlled sessions, not from one large swing.

If you pass and move to a Prop account, payouts are real money paid by TradeFundrr from its own funds when you meet the written payout rules. They are never guaranteed. The trading itself stays simulated, so the work of sizing correctly is the same on the first day of the evaluation as it is after you are funded.

Frequently Asked Questions

What are XSP options?

XSP options are Cboe-listed options on the Mini-SPX Index, which is based on one tenth the value of the S&P 500. They are cash settled and European style, like SPX options, and each contract uses a $100 multiplier, so one XSP contract is one tenth the size of one SPX contract.

How many XSP contracts equal one SPX contract?

Ten. Cboe states the relationship as one SPX equals ten XSP, because the Mini-SPX Index is one tenth of the S&P 500 and both products use the same $100 multiplier.

Is XSP better than SPY for day trading?

Neither is better in general. XSP is cash settled and European style, so in a live account it avoids share delivery and early assignment. SPY options are often more heavily traded, which can mean tighter spreads. The right choice depends on which products your platform offers, the spread you pay and the size your risk budget can carry.

Are XSP options less risky than SPX options?

Each XSP contract has about one tenth of the dollar exposure of an SPX contract, so it risks fewer dollars per index point. That does not make the product safer. An XSP option can still lose its full premium, and holding ten XSP contracts carries roughly the same risk as one SPX contract.

Can I trade XSP options in a TradeFundrr funded account?

XSP is not on the published list of underlyings for TradeFundrr's options accounts, which names index options including SPX and ETF options on SPY, QQQ and IWM. Confirm on your own platform whether XSP is offered before planning a trade around it.

Do XSP options get assigned in a simulated funded account?

No. Assignment and cash settlement are live-market events that require a real trade with a real counterparty. In a TradeFundrr simulated account no real trade is executed, so nothing is assigned or settled by an exchange. The accounts are intraday only, so plan to close positions before trading ends at 3:55 PM ET.

What daily loss limit applies to a TradeFundrr options evaluation?

On the options Pre-Prop evaluation, the daily loss limit is $1,000. Reaching it pauses trading for the session, and the limit resets the next trading day. Separately, a $3,000 maximum drawdown trails your highest end-of-day balance, and reaching it closes the account.

Does a TradeFundrr options account trade real money?

No. Pre-Prop and Prop options accounts are simulated, and no real trade is executed. The fees you pay are real, and payouts on a Prop account are real money paid by TradeFundrr from its own funds when you meet the written payout rules.
