Top 10 Best Option Flow Screeners and Scanners in 2024

Let’s cut straight to the chase. Here are the ten leading options screeners based on our latest research.

1. TrendSpider

The platform boasts technical tools and has an AI-powered charting feature to guide you quickly on the best options to choose. This market scanner focuses on price action besides charts and thus has few filters, making it easy to navigate.

The platform features a feature called Options Flow that allows traders to monitor options sweeps, stock options and helps keep a record of best block trades. Other notable features are the heat map, the platform's ability to analyze strike prices, option prices, and the expiration price for each options contract.

TrendSpider is a premium platform that, unfortunately, doesn't include a free version. There are three subscription plans: premium ($33 per month), elite ($65 per month), and advanced ($97 per month). Although the premium version has the best essential functions, the TrendSpider advanced option gives more detailed data for every scan.

2. Market Chameleon

Options and stock traders love Market Chameleon's data analysis and screening features. Some primary features of the options icon include unusual options volume, options volumes, implied volume rankings, snapshot, and buy writes search. This provides a detailed overview of the options market for traders to make sound decisions.

The stocks option expands to premarket trading, after-hours trading, market movers, unusual stock volume, etc. Traders can get lists of top gainers or losers on high volume, view outperforming stocks and dividends like REITs, MLPs, or closed-end funds. Premium users can access reports on new listings, splits, order imbalances, and performance by industry or mergers.

Unlike other platforms in this list, like Trendspider and Insider Finance, which have no free option, Market Chameleon provides users a free 7-day trial. The $99 monthly subscription grants users total access to the platform's outstanding options screeners, data analysis tools and stock research.

3. Insider Finance

Other integrated features within the Insider finance tool include charting, annotations like trend lines, and trading indicators for detailed technical analysis.

A one-click dashboard featuring Equities, Unusual Sweeps, Momentum, ETFs, and Moonshots is easy to use and can be customized to give specific results. Insider Finance's powerful data-driven tools give you an upper hand in trading and investment, but this is at a cost. The three plans, $75 per month, $195 per quarter, and $660 annually, give subscribers complete success for all features.

Since PowerX Optimizer is a web-based platform, traders won't need to install apps or update their DVDs or CDs whenever there's a software update. However, to use the platform, you need to part with a license fee, which costs $3,997 for lifetime use with no extra costs.

6. Bar Chart

This platform stands out with its ability to offer a combination of screening and charting benefits. As a first-time user, you'll be amazed at how clean and easy this site's layout really is. So, even if you're non-tech-savvy this screener is sure to make it really easy for you to get on board with remarkable ease.

A free membership account is available and it shows most of the basic information you need to make solid decisions. However, you only get delayed data (15-minute delay) when you opt for the free mode.

The premium membership option, however, comes with better perks. Besides providing you with live data you get advanced screeners along with the ability to run a screener on your watchlist.

In a nutshell, BarChart is a feature-rich options screener that offers beginner-friendly features along with some of the most advanced screeners in the game.

The platform is designed to streamline the task of identifying emerging opportunities in the world of options, particularly by leveraging real-time data to identify unusual activities in the options market.

Plans start from as low as $49 per month for the Beginner plan to as high as $75 per month for the Advanced tier.

Is a Free Options Scanner Worth It?

Most E-trade platforms and brokers, such as TD Ameritrade, use free options screeners. Free options screeners are great for new traders who are still learning the ropes and won't have to part with hefty subscription fees.

Fortunately, some options platforms in the list above have free versions for users to get accustomed to. This is helpful as users only pay for the option screener after evaluating its worthiness. 

Using free options screeners may sound enticing initially; however, they limit users on the quality of data they get. Accessing high-quality trading data is costly since related data exchanges involve money. Before venturing into paid options platforms, traders should conduct quality assessments to ascertain if they are worth investing in. 

What to Look for in a Option Flow Scanner?

The ever-complex online trading market makes it hard for new users to choose effective trading options. First, you should define your objective for trading, including the type of options outlook, selling or buying options, or hedging against possible risk. Also, determine the volatility of every option as it will affect its ultimate price and reward/risk payoff before making a final choice.

Identify events that are stock-specific or market-wide events. Stock-specific events include product launches, spinoffs, or earnings reports, while market-wide events affect large markets' economic data releases or Federal Reserve announcements.

Finally, after deciding which option scanner to use, now establish parameters like strike prices, option deltas, and expiration dates for better trading.


Options flow scanners are vital tools in trading since they provide users with the best market probable analysis and data features. The FinViz, Market Chameleon, and Trading View have free/paid options, thus making them great for market testing. PowerX Optimizer, TrendSpider, Insider Finance, and BlackBoxStocks are premium tools offering detailed data scanning options.

You are either a new trader confused about what options screeners to pick or a pro trader who wants to experience new trading platforms. Don't worry, the above list comprises the best options screeners available on the market today. All you have to do is understand the specs of each option and pick one that meets your market needs.
