Check Any Stock's Options Liquidity
Before You Trade
See bid-ask spreads, volume depth, open interest, and slippage estimates for 4,200+ stocks. Stop getting bad fills.
Options liquidity measures how easily you can buy or sell options contracts without significant price impact. A liquidity score of 6.0+ (on a 0-10 scale) means tight bid-ask spreads under 1%, daily volume above 2,000 contracts, and open interest above 10,000. This tool scores 4,200+ stocks using spread analysis (40%), volume depth (30%), and open interest (30%). Iron condors need a minimum score of 7.0 due to 4-leg execution cost.
Common Options Liquidity Problems
Real traders, real problems — from Reddit
The fills on tastytrade are horrible
Even when the market moves through my limit, the fills don't come. I'm stuck sitting on mid-price while opportunities pass.
Does anyone have a system for predicting fill price?
My actual fills on credit spreads are less than half the mid. The slippage is destroying any edge I thought I had.
Options Orders not filling
I've placed quite a few orders for various iron condors on SPY and the orders aren't filling despite high volume.
Moved from full automation to manual execution
Slippage destroyed edge and fill quality on multi-leg options made automation impractical.
How We Check Options Liquidity For Each Problem
Every pain point maps to a specific data check in our tool
Why Won't My Order Fill?
Options Orders not filling
I've placed quite a few orders for various iron condors and the orders aren't filling despite high volume.
Orders don't fill when there aren't enough counterparties at your price. Our liquidity score combines bid-ask spread (40%), volume depth (30%), and open interest (30%) to tell you before you trade.
Rule: Score ≥6.0 = orders should fill with limit orders. Score <4.0 = expect problems.
Why Am I Getting Bad Fills?

Even when the market moves through my limit, the fills don't come.
Spreads widen dramatically away from ATM. Your broker isn't the problem — the spread at your strike is. Our tool shows the exact spread cost at every delta range.
Rule: Check the spread at your actual delta, not just the ATM spread the broker shows you.
Slippage Is Eating My Edge
Does anyone have a system for predicting fill price?
My actual fills on credit spreads are less than half the mid.
Slippage scales with order size and spread width. Our tool estimates the real execution cost for your order size before you trade.
Rule: If estimated slippage > 1/3 of your expected profit, the trade isn't worth it.
I'm Stuck in a Position I Can't Close
How do you handle catalyst plays when the options chain is basically unusable?
Small cap options chains are too thin. I can't roll, I can't adjust, I'm just stuck.
If multi-strike and multi-expiry checks fail, you can't roll or adjust. Check before entering.
Rule: If fewer than 5 strikes are liquid, you're one bad move away from being trapped.
My Iron Condor Costs More Than It Makes
Moved from full automation to manual execution
Slippage destroyed edge and fill quality on multi-leg options made automation impractical.
Multi-leg strategies multiply execution costs. An iron condor = 4 legs × spread. Our strategy gate tells you the minimum liquidity each strategy needs.
Rule: Iron condors need liquidity score ≥7.0. Below that, stick to single-leg or 2-leg strategies.
The Real Cost of "Commission-Free"
In March 2025, FINRA fined Robinhood $26 million for collaring issues that led to worse execution prices for customers from 2016-2021. See the discussion on r/options →
The 3 hidden costs commission-free brokers don't show you:
- Bid-ask spread — the % you lose on every trade
- Slippage — the gap between your limit and actual fill
- Multi-leg multiplication — spread × number of legs

Liquidity Is 1 of 5 Questions We Ask Before Every Trade
Before every trade, we check 5 conditions: VALUE (is IV priced right?), SENTIMENT (what are traders doing?), ACTIVITY (unusual activity?), LIQUIDITY (can you trade efficiently?), TIMING (good time to enter?).
Frequently Asked Questions
How do I check if an options contract has good liquidity?
Enter any ticker in the checker above. A liquidity score of 6.0+ means the options chain has tight spreads, sufficient volume, and deep open interest. Look at the sub-checks: ATM spread should be under 1%, daily volume above 2,000 contracts, and total open interest above 10,000. Scores below 4.0 indicate poor liquidity where fills will be difficult.
What is a good bid-ask spread for options?
ATM options on liquid stocks like SPY typically have spreads under 0.3%. A spread under 1% is generally considered good for most stocks. Above 2%, execution costs become significant. Our tool grades spreads from A+ (under 0.5%) to D (over 3%) at each delta range, so you can see the exact cost at your target strike.
Why is my options order not filling?
The most common reason is insufficient liquidity at your strike price. Even if a stock has high volume at ATM strikes, OTM options can have spreads 3-5x wider. Multi-leg orders like iron condors require liquidity at 4 different strikes simultaneously, making fills harder. Use our checker to verify liquidity before placing orders.
What is options slippage and how much does it cost?
Slippage is the difference between the expected fill price and the actual execution price. It increases with order size and spread width. For liquid stocks, expect 0.1-0.5% on small orders (1-10 contracts). For 50+ contracts, slippage can reach 1-3%. Our tool estimates slippage at each order size tier.
How do I avoid bad fills on options trades?
Check the liquidity score before trading — anything below 6.0 means you'll fight for fills. Always use limit orders, never market orders. Trade during peak hours (10AM-3:30PM ET). For multi-leg strategies, check that all legs have sufficient open interest. Our tool shows exactly where liquidity breaks down.
Why won't my iron condor fill?
Iron condors require liquidity at 4 different strikes. Even on high-volume stocks, the OTM wings often have wider spreads. Our strategy gate shows that iron condors need a minimum liquidity score of 7.0. Below that, the combined spread across 4 legs makes fills unreliable. Check the spread-by-delta breakdown to see where the problem is.
What does PFOF mean for my options fills?
Payment for Order Flow (PFOF) is how commission-free brokers make money — they route your orders to market makers who may not give you the best price. FINRA fined Robinhood $26M for collaring issues related to this. While PFOF isn't inherently bad, it means checking execution quality matters more than checking commission rates.
