Options Scanner: How to Set Practical Criteria
Learn how an options scanner differs from an equity scanner, which criteria to set, and how to evaluate results with a paper-first process.
Put this into practice with a watchlist
Build a watchlist, then review each signal’s entry, stop, target, and reasoning. Broker access is optional.
An Options Scanner Starts With Contract Risk
An options scanner screens contracts or their underlying symbols using criteria such as volume, open interest, strike, expiration, and implied volatility. Unlike an equity-only tool, it must account for a contract's time sensitivity, liquidity, and potential exercise or assignment considerations.
For equity-focused filters, see the stock scanner guide. For feeds centered on reported option trades, see options flow scanner.
Options Scanner Versus Equity Scanner
An equity scanner might flag price gaps, relative volume, or a breakout. An options scanner adds a second decision layer: which contract, if any, matches the time horizon and risk limit? A promising underlying does not make every call or put appropriate.
Review the expiration, strike distance, bid-ask spread, and implied volatility. Ask how the position behaves if the stock stalls, moves slowly, or moves against the thesis. A scanner result is an invitation to calculate, not a conclusion.
Criteria Worth Defining Before You Scan
Underlying Universe
Start with liquid names you can research. This limits the temptation to follow a thinly traded contract simply because its percentage move looks dramatic.
Contract Liquidity
Use volume and open interest as signals to inspect a market, then check the live spread. A wide spread can materially change entry and exit assumptions.
Time and Event Exposure
Set an expiration range consistent with the anticipated catalyst and your plan. Earnings, economic releases, and dividend dates can alter pricing quickly. Do not let a scanner's short list substitute for an event calendar.
Risk Limit
Decide the maximum hypothetical loss and invalidation point first. A stop-loss may not execute at an expected price in a fast market, particularly for less-liquid contracts.
Put the setup on a watchlist first
Use the rules in this guide to evaluate a signal’s entry, stop, target, and reasoning before deciding what, if anything, to do.
A Simple Paper Workflow
Choose one underlying filter and one contract filter. Record every result that qualifies over a planned window, then assess its chart context and define a paper entry and exit. Include a realistic spread rather than using a favorable last trade.
Compare this log with the ideas surfaced by options alerts. The goal is to find a workflow you can explain, not to maximize the number of alerts.

Frequently Asked Questions
Should I scan calls and puts separately?
That can make the results easier to review, but direction labels alone do not establish intent. Keep the underlying chart and risk plan in the evaluation.
Does high open interest guarantee easy exits?
No. Open interest is not a direct measure of current bid-ask depth. Check the quoted spread and available size when planning a hypothetical fill.
Can an options scanner choose a strategy for me?
No. A scanner can filter data, but strategy selection requires a defined objective, payoff, risk, and ability to manage the position.
Tradewink is not an investment adviser. Options can lose value rapidly and involve substantial risk. This educational material is not a recommendation to trade.
