Choosing an Option Strike for Day Trades: ITM, ATM, or OTM in 2026
Two traders can be right about direction on the same stock and still get very different results, because they picked different strikes. Choosing an option strike is the decision that sits underneath every other options call you make, and for a day trade it often matters more than the entry itself.
The strike is simply the price at which the option can be exercised. Where you set it relative to the current price decides whether the option is in-the-money, at-the-money, or out-of-the-money, and that single choice drives the delta, the premium you pay, and how the position behaves through the day.
In this guide we will define the three strike zones, show how delta ties a strike to price movement, explain why liquidity usually beats a cheap premium, and walk through how choosing an option strike works inside a structured, simulated funded account where you are flat by the close.
Key Takeaways
- Anchor on moneyness. A strike is in-the-money, at-the-money, or out-of-the-money depending on where it sits versus the current price, and that sets everything else.
- Read the delta. Delta estimates how much the option moves per point in the underlying, so it is a fast gauge of how responsive a strike will be.
- Respect liquidity. A tight bid-ask spread and healthy open interest matter more for a day trade than the cheapest premium on the chain.
- Match the strike to the plan. Pick the strike that fits your expected move, hold time, and risk per trade, not the one with the flashiest payoff.
- Remember the account is simulated. You practice strike selection on real data without real capital, and you never carry assignment risk if you close before the bell.

What Choosing an Option Strike Means
Choosing an option strike means selecting the exercise price of the contract relative to where the underlying is trading right now. That relationship, called moneyness, sorts every strike into one of three zones, and each zone behaves differently before you have even placed the trade.
The three zones
An in-the-money call has a strike below the current price, so it already holds intrinsic value and moves closely with the stock. An at-the-money strike sits right around the current price, carries the most time value, and has a delta near 0.50. An out-of-the-money call has a strike above the current price, so it is all time value, costs the least, and needs the underlying to move before it pays off. Puts work the same way in reverse. The Options Industry Council keeps a clear, unbiased primer on these definitions if you want the textbook version alongside this one.
Why the zone is the first decision
The zone you choose is a trade-off between cost and probability. Out-of-the-money strikes are cheap because they are less likely to finish in the money. In-the-money strikes cost more because a large part of what you pay is real value you could exercise today. At-the-money strikes sit in the middle, which is why they draw so much day-trading volume. Nothing here is a shortcut, and no strike is free money. It is a question of which trade-off fits the move you expect.

tradefundrr.comHow Delta Ties a Strike to Movement
Delta is the fastest way to judge a strike, because it estimates how much the option's price changes for a one point move in the underlying. A strike with a 0.60 delta moves roughly 60 cents for every point the stock moves, while a 0.20 delta strike moves about 20 cents for the same point. For a day trade, that responsiveness is often the whole point.
Delta as a responsiveness gauge
Higher delta strikes, which tend to be at-the-money or in-the-money, react more directly to the move you are trying to capture. Lower delta strikes lag until the underlying travels far enough to bring them to life. If your plan is to catch a quick intraday push and be out within the hour, a strike that only wakes up after a large move is working against your clock. Our post on options delta explained breaks down the number in more depth.
Delta is not a promise
Delta is an estimate that shifts as the price moves, as time passes, and as volatility changes. It is a useful compass, not a guarantee. Two things can pull an option away from the move you expected even when you are right on direction: time decay eating the premium, and a drop in implied volatility after an event. Our post on implied volatility and option pricing covers that second force, which routinely surprises newer options day traders.
Liquidity and Spread Beat a Cheap Premium
For a day trade, liquidity usually matters more than finding the cheapest strike, because you have to sell what you bought within hours. A strike with tight bid-ask spreads and solid open interest lets you enter and exit near fair value, while a thin strike can quietly hand back your edge on the way out.
The hidden cost of a wide spread
Say an out-of-the-money strike is quoted at 0.40 bid and 0.55 ask. You are down more than a third of the position the instant you buy, before the stock moves at all, simply because you would have to sell at the bid. A liquid at-the-money strike quoted 1.20 by 1.23 costs pennies to cross. Over one trade the difference looks small. Over a hundred trades it is the difference between a workable process and a leak you cannot plug. The Cboe Options Exchange publishes volume and open interest data that helps you spot which strikes actually trade.
What to check on the chain
Before committing to a strike, glance at the bid-ask spread, the open interest, and the volume for that specific contract. Healthy open interest means other traders are active in that strike, which tends to keep spreads tight. Our post on open interest and options liquidity shows how to use those figures as a liquidity filter rather than an afterthought.
| Factor | In-the-money | At-the-money | Out-of-the-money |
|---|---|---|---|
| Strike vs price | Below (calls) | Near the price | Above (calls) |
| Approx delta | 0.70 or higher | Around 0.50 | 0.30 or lower |
| Premium cost | Highest | Middle | Lowest |
| Move needed to profit | Small | Moderate | Larger |
| Typical liquidity | Good | Best | Varies, often thinner |
| Common day-trade use | Higher conviction | Balanced default | Cheap lottery-style bets |

Matching the Strike to Your Day-Trade Plan
The right strike is the one that fits your expected move, your hold time, and your risk per trade, in that order. Work backward from the plan instead of forward from the price tag, and the choice gets much simpler.
Start with the move you expect
If you expect a small, quick move, a higher delta strike near the money will capture more of it. If you are positioning for a larger move and want to keep the cost of being wrong low, a further out-of-the-money strike can make sense, as long as you accept the lower odds. The strike should express the specific trade thesis, not a general hope that the stock goes up.
Size the position to the premium
Because a cheaper strike lets you buy more contracts for the same dollars, it is easy to oversize without noticing. Decide your risk per trade first, then let that cap the number of contracts, whatever strike you land on. Our post on how much to risk per trade walks through keeping premium risk constant across positions.
- Name the move you expect, in points and in time, before you open the chain.
- Pick the moneyness zone that fits that move, not the cheapest line on the screen.
- Check the delta as a responsiveness gauge for your hold time.
- Confirm the bid-ask spread and open interest are tight enough to exit fast.
- Size contracts off your risk per trade, not off the premium being cheap.
- Confirm the strike and expiration are allowed under your account rules.
Choosing Strikes in a Simulated Account
In a TradeFundrr funded account you trade options in a simulated environment on real market data, so you can practice choosing an option strike exactly as you would live, without your own capital at risk. The chain, the deltas, and the spreads are real inputs. What is not real is the settlement, because no trade is executed against a live counterparty.
Assignment is a live event, not a sim event
Assignment happens in the live market when a real counterparty exercises an option, usually against a short position held into expiration. In a simulated account no real transaction takes place, so assignment does not occur the way it would on a live desk. For a day trader who is flat before the close, the question rarely comes up at all. We still cover it because being ready for it is part of trading options for real, and our post on assignment risk for funded options treats it as the live-ready skill it is.
Why the practice transfers
Strike selection is a skill that carries over cleanly from a simulated account to a live one, because the inputs are identical. You are reading the same deltas, weighing the same spreads, and matching the same strikes to the same kind of move. The simulated environment lets you build that judgment under written rules, with your risk per trade and daily loss limit defined up front, so the habits you form are the ones a live desk rewards.
Frequently Asked Questions
What does choosing an option strike mean?
Choosing an option strike means picking the price at which the option can be exercised, relative to where the underlying is trading. That choice sets the option in-the-money, at-the-money, or out-of-the-money, which in turn decides its delta, its premium, and how much it moves per point in the underlying.
Which option strike is best for day trading?
There is no single best strike. Many day traders favor at-the-money or slightly in-the-money strikes because they carry a delta near 0.50 or higher, tighter spreads, and enough liquidity to enter and exit fast. Far out-of-the-money strikes are cheaper but move less reliably and can be harder to sell.
What is the difference between ITM, ATM, and OTM strikes?
In-the-money strikes already have intrinsic value and a high delta. At-the-money strikes sit closest to the current price with a delta near 0.50 and the most time value. Out-of-the-money strikes are all time value, cost the least, and carry a low delta, so they need a bigger move to pay off.
How does delta help you choose a strike?
Delta estimates how much an option's price changes for a one point move in the underlying. A 0.60 delta option moves about 60 cents per point, so a higher delta strike tracks the underlying more closely. Day traders often use delta as a quick read on how responsive a strike will be.
Can I trade any option strike in a funded account?
A funded account may limit which strikes or expirations you can trade, along with position size and daily loss. TradeFundrr accounts are simulated, so always confirm the strike, expiration, and risk rules written into your own account before you build a trade around a specific strike.
Do cheaper out-of-the-money strikes give more leverage?
They give more leverage per dollar spent, but that cuts both ways. A low premium out-of-the-money strike can multiply fast on a strong move, yet it can also decay to zero if the move never comes. The lower cost is paid for with a lower probability that the strike finishes in the money.
Why does liquidity matter more than a cheap premium?
A day trade only works if you can exit at a fair price. A cheap strike with a wide bid-ask spread and thin open interest can cost more on the way out than you saved on the way in. Liquid strikes with tight spreads keep your slippage small, which matters far more over many trades.
Does choosing a strike involve assignment risk in a simulated account?
Assignment is a live-market event that happens when a real counterparty exercises. In a simulated funded account no real trade is executed, so assignment does not occur the way it would live. A day trader who is flat by the close avoids the situation entirely, but it is still worth learning as a live-ready skill.
