Volume is one of the first numbers you’ll look at on an options chain — and one of the most misunderstood. Most beginners treat it as a simple activity counter. Experienced traders use it as a liquidity filter, a signal detector, and a position management tool.
Understanding volume properly changes how you select contracts, evaluate trades, and interpret market activity. This guide covers exactly what options volume means, how it differs from open interest, and how to use it practically in your trading.

What Is Options Volume?
Options volume is the total number of contracts traded for a specific option during the current trading session. Every time a contract changes hands — whether bought or sold — it adds to that day’s volume count.
Volume resets to zero at the start of each new trading day. It’s a snapshot of today’s activity — not a cumulative record of all outstanding positions.
How volume accumulates:
- Trader A buys 10 call contracts → volume increases by 10
- Trader B sells 5 put contracts → volume increases by 5
- Trader C closes 3 call contracts → volume increases by 3
- End of day total volume for those contracts: 18
Note that both opening and closing transactions count toward volume. A trader buying to open and another trader selling to close both contribute to the same volume number.
Volume vs Open Interest
Volume and open interest are the two most important activity metrics on the options chain — and the most commonly confused. They measure fundamentally different things.
Volume — how many contracts traded today. Resets daily.
Open interest — how many contracts currently exist in the market. Updated overnight after each session. Represents all open positions that haven’t been closed or exercised yet.
Example:
| Metric | Number | What it means |
|---|---|---|
| Volume today | 2,000 | 2,000 contracts changed hands today |
| Open interest | 5,000 | 5,000 contracts are currently open across all traders |
The key relationship: When today’s volume significantly exceeds open interest, it typically means new positions are being opened — not just existing positions being traded. A contract with 500 open interest and 3,000 volume today is seeing major new activity — worth paying attention to.
When volume is lower than open interest, the activity is largely existing position management — closing, rolling, or adjusting — rather than new money entering the market.
For a complete breakdown of open interest and how it differs from volume see our guide on What Is Open Interest in Options.
Why Volume Matters for Options Traders
Volume matters for one primary reason: liquidity. And liquidity affects every single trade you make.
Liquidity is how easily you can enter and exit a position at a fair price. High-volume options have tight bid-ask spreads — the difference between what buyers will pay and what sellers will accept. Low-volume options have wide spreads that silently eat into your profit on every trade.
The spread math:
| Option | Volume | Bid | Ask | Spread | Cost to trade |
|---|---|---|---|---|---|
| Option A | 5,000 | $1.45 | $1.50 | $0.05 | $5 per contract |
| Option B | 25 | $1.20 | $1.60 | $0.40 | $40 per contract |
Option B costs 8x more to trade just from the spread — before any market movement. On a 10-contract position that’s $400 in hidden friction versus $50. This is why experienced traders check volume before entering any position regardless of how attractive the premium looks.
Volume and trade execution:
High-volume contracts fill quickly at or near the midpoint between bid and ask. Low-volume contracts may not fill at all at your desired price — or may move the market against you just by trying to enter. For a complete guide on evaluating liquidity on the options chain see our How to Read the Options Chain guide.
What Counts as Good Volume?
There’s no universal minimum — but here are the practical thresholds most experienced traders use:
| Volume Level | Assessment | Practical Use |
|---|---|---|
| Under 10 | Very illiquid | Avoid — spreads will be wide and fills unreliable |
| 10-100 | Low | Proceed with caution — check bid-ask spread carefully |
| 100-500 | Moderate | Acceptable for 1-2 contract positions |
| 500-2,000 | Good | Solid liquidity for most retail position sizes |
| 2,000+ | Excellent | Easy entry and exit for any retail size |
| 10,000+ | Exceptional | Institutional-grade liquidity |
These thresholds apply to individual strikes — not to the total options volume for the stock. A highly liquid stock like AAPL or SPY will have multiple strikes with 10,000+ volume daily. A small-cap stock might have its most active strike at 200-300 contracts — which is fine for a 1-5 contract position but not for 50 contracts.
The practical rule: Before entering any options trade check that the strike you’re targeting has at least 100 contracts of volume and the bid-ask spread is less than 10% of the option’s price. For a $2.00 option that means a spread under $0.20. Anything wider and you’re paying too much just to get in.
Volume and Open Interest Together: The Real Signal
Analyzing volume and open interest together gives you more information than either metric alone. Here are the four key combinations and what they typically mean:
| Volume | Open Interest | Interpretation |
|---|---|---|
| High | Low | New positions being opened aggressively — significant new activity |
| High | High | Active market with both new and existing positions trading |
| Low | High | Existing positions being managed — little new interest today |
| Low | Low | Illiquid contract — avoid |
The most interesting signal is high volume with low open interest — it means significant new money is entering a contract that wasn’t previously active. This is often the pattern that shows up before a major announcement or catalyst. For a complete guide on reading these signals see our How to Spot Unusual Options Activity guide.
Unusual Options Volume
Unusual options volume occurs when a contract’s trading activity spikes dramatically above its normal level — often 5x, 10x, or more above average daily volume.
Example:
- Normal daily volume for a specific call: 150 contracts
- Today’s volume: 4,500 contracts
A 30x spike in volume on a specific strike and expiration is a meaningful signal. It typically means a large trader or institution has entered a significant position — potentially ahead of an anticipated move.
What unusual volume can signal:
- Institutional positioning before earnings
- Insider-adjacent activity ahead of major announcements
- Hedge fund positioning on anticipated sector moves
- Large spread construction that creates volume on multiple strikes simultaneously
What unusual volume doesn’t tell you:
- Which direction the large trader is betting
- Whether the trade is directional or a hedge
- Whether the signal will play out as expected
Volume alone never confirms direction. A large call purchase could be a bullish directional bet — or it could be a hedge against a large short stock position. Context, strike selection, expiration, and whether trades executed at the bid or ask all provide additional color. For a complete framework on interpreting unusual activity see our How to Spot Unusual Options Activity guide.
Volume by Time of Day
Options volume is not evenly distributed throughout the trading session — and understanding the pattern helps you interpret what you’re seeing.
Market open (9:30-10:30 AM ET): Volume spikes sharply as overnight orders execute and traders react to pre-market news. Bid-ask spreads are typically wider during this window. Most experienced traders avoid entering new positions in the first 15-30 minutes.
Mid-morning (10:30 AM-12:00 PM ET): Volume settles into a more predictable rhythm. Spreads tighten as market makers establish their books. This is typically the best window for entering new positions.
Midday (12:00-2:00 PM ET): Volume typically dips. Less activity means slightly wider spreads on less liquid contracts. Fine for liquid large-cap options — worth monitoring on smaller names.
Late afternoon (2:00-4:00 PM ET): Volume picks up again as traders position into the close. The final 30 minutes before 4:00 PM often sees sharp volume spikes — particularly around expiration dates as traders close or roll expiring positions.
Practical takeaway: Check volume in the mid-morning window before entering positions. Early-morning volume numbers can be misleading — a contract that shows 2,000 contracts by 9:45 AM may only have 500 by 10:30 AM as the initial burst settles.
How to Use Volume in Practice
Here’s exactly how to incorporate volume into your trading process:
Step 1 — Check volume before selecting any strike
Before committing to a specific strike price confirm that today’s volume is at least 100 contracts and preferably 500+. If volume is under 50 consider a nearby strike with better activity.
Step 2 — Compare volume to open interest
Calculate the volume-to-open-interest ratio. Above 0.5 (50% of open interest traded today) indicates active markets. Above 2.0 (volume exceeding open interest) signals significant new activity worth investigating.
Step 3 — Check the bid-ask spread
High volume generally means tight spreads — but always verify. Target fills at or near the midpoint between bid and ask. For a $1.50/$1.60 option that’s $1.55. Set limit orders at the mid rather than accepting the ask price.
Step 4 — Use volume to confirm liquidity for rolling
If you’re running covered calls or cash-secured puts as part of The Wheel Strategy, check volume on your target roll strikes before rolling. Poor volume on the new strike means you may struggle to get filled at a fair price — potentially adding friction costs to every management action.
Step 5 — Monitor for unusual volume on your existing positions
Sudden spikes in volume on strikes near your position can signal upcoming volatility. Not a reason to close automatically — but worth noting as you monitor positions.
Common Beginner Misunderstandings
“High volume predicts price direction”
Volume tells you how many contracts traded — not which direction traders are betting. A day with 10,000 call contracts traded is meaningless without knowing whether those were bought or sold, at the bid or ask, and what the overall market context is. High volume signals interest — not conviction about direction.
“Volume and open interest are the same thing”
They measure completely different things. Volume resets daily and shows today’s activity. Open interest accumulates over time and shows all outstanding positions. A contract can have low volume today and high open interest from positions built over weeks — or high volume today with low open interest if it’s newly active. Use both together. See our guide on What Is Open Interest in Options.
“Low volume options are fine for small trades”
Low volume means wide bid-ask spreads regardless of position size. Even a 1-contract trade on a $1.20/$1.60 spread option costs $40 just to enter — before the stock moves at all. Always check the spread before entering any position regardless of how small.
“I should only look at total stock options volume”
Total daily options volume for a stock aggregates all strikes and expirations. What matters for your specific trade is the volume at your specific strike and expiration. A stock can have 500,000 total options contracts traded today while your specific $105 strike expiring next Friday has only 12 contracts — making it completely illiquid for practical purposes.
Which Broker Shows Volume Best?
Not all broker platforms display options volume equally well. Here’s what to look for:
- tastytrade — displays volume, open interest, and bid-ask spread clearly on the options chain. The layout is designed for active options traders and makes liquidity evaluation straightforward
- thinkorswim (Schwab) — the most customizable options chain display in retail brokerage. Can add volume columns, volume-to-OI ratio, and unusual activity flags simultaneously
- Webull — shows volume and open interest on the chain with a clean mobile interface. Good for quick liquidity checks before entering positions
- Fidelity (Active Trader Pro) — strong options chain with volume and open interest clearly displayed. Best for traders who also want fundamental research alongside their options data

Final Thoughts
Volume is the first filter every options trader should apply before entering any position. It tells you whether a market exists for the contract you want to trade — and whether you’ll be able to enter and exit at fair prices.
The practical process is simple: check volume before selecting any strike, verify the bid-ask spread is tight, compare volume to open interest for context, and avoid low-volume contracts regardless of how attractive the premium looks on paper.
Combined with open interest, implied volatility, and Delta, volume gives you a complete picture of any options contract before you commit capital. Master these basic metrics and you’ll avoid most of the execution mistakes that cost beginners money before a trade even has a chance to work.

Frequently Asked Questions
What is volume in options trading?
Options volume is the total number of contracts traded for a specific option during the current trading session. It resets to zero at the start of each new trading day. Higher volume indicates more active trading and generally better liquidity — tighter bid-ask spreads and easier trade execution. Volume is one of the first metrics to check before entering any options position.
What is a good volume for options trading?
Most experienced traders look for at least 100 contracts of daily volume at their specific strike before entering a position — with 500+ preferred for comfortable liquidity. Contracts with volume under 50 typically have wide bid-ask spreads that make trading expensive. For larger position sizes (10+ contracts) target strikes with 1,000+ daily volume to ensure smooth entry and exit.
What is the difference between volume and open interest in options?
Volume measures how many contracts traded today — it resets daily. Open interest measures how many contracts currently exist across all traders — it accumulates over time and updates overnight. Both metrics together tell you more than either alone. High volume with low open interest signals significant new activity. High volume with high open interest signals an actively traded contract with both new and existing positions in motion. See our complete guide on What Is Open Interest in Options.
Does high options volume mean the stock will move?
Not necessarily. High volume signals that many traders are active in a specific contract — but it doesn’t reveal whether they’re bullish or bearish, or whether a move is imminent. Unusual volume spikes — particularly when combined with at-ask execution on out-of-the-money options — can suggest institutional positioning ahead of a catalyst. But volume alone never confirms direction. See our guide on How to Spot Unusual Options Activity.
Why does options volume matter for covered call traders?
For covered call and cash-secured put traders liquidity directly affects income. Wide bid-ask spreads on low-volume contracts reduce the premium you actually collect versus what’s quoted. They also make rolling — the core management technique for income traders — more expensive. Always check volume at your target strike before selling covered calls or puts. Aim for 500+ contracts of daily volume for reliable liquidity. For a complete covered call guide see our Covered Call Strategy post.
What does unusual options volume mean?
Unusual options volume occurs when a contract’s trading activity spikes significantly above its normal level — often 5x or more. It typically signals that a large trader or institution has entered a meaningful position, potentially ahead of an anticipated catalyst. Unusual volume is worth monitoring but should never be traded on alone — context, strike selection, expiration, and bid-ask execution all provide additional information about what the activity means. See our complete guide on How to Spot Unusual Options Activity.
How do I find options volume on my broker platform?
Options volume appears as a column on the options chain — typically labeled “Volume” or “Vol.” It shows the number of contracts traded today at each specific strike and expiration. Most platforms also show open interest in an adjacent column. Check both before entering any position. For a complete walkthrough of the options chain and what each column means see our How to Read the Options Chain guide.
Should I avoid trading options with low volume?
Generally yes — low volume means wide bid-ask spreads that make every trade more expensive. Even a 1-contract position on a low-volume option with a $0.40 spread costs $40 just to enter before the stock moves at all. The rare exception is when you’re deliberately targeting a specific illiquid strike for a specific strategic reason — but for most income trading and directional trades stick to contracts with at least 100 daily volume and spreads under 10% of the option’s price.
