Get Started with StockFilters
What is StockFilters?
StockFilters is a modern stock market screener built for retail traders who are serious about their edge. Developed by verified 8-figure trader Lance Breitstein, it combines customizable filters, fresh market data, and built-in AI trading tools to give everyday traders access to the same intelligence institutional traders have relied on for years.
Who is StockFilters for?
StockFilters is built for active traders, including day traders and swing traders, who want more control over how they find and filter trade opportunities. Whether you are new to screening or looking to replace your current day trading tool with something faster and more flexible, StockFilters was designed with you in mind.
How do I access StockFilters?
StockFilters can be accessed two ways. You can purchase access directly from this site, or if you are an Advanced or Elite tier Magnum Opus member, access is already included as part of your membership.
Do I need coding experience to use StockFilters?
No. The StockFilters AI assistant lets you describe what you are looking for in plain language and builds the filter for you. For those who want to write their own queries, the syntax follows familiar SQL-style logic that is straightforward to learn with the help of the built-in Documentation.
Tool Features
Can I build my own custom filters?
Yes. The New Filter page is where you write fully customizable queries using a SQL-style syntax. You can chain conditions using AND and OR statements, run them against live market data, and save them to your personal library. It functions as a true automated trading system software, notifying you of stocks that meet your exact criteria without manual checking.
How do I find stocks in-play using StockFilters?
StockFilters was built specifically to help active traders identify stocks in-play quickly and precisely. Using Lance’s pre-built filters alongside live market intraday data, you can scan the entire market in seconds and surface the exact setups you are looking for — without manual searching.
What are Lance's Filters and can I edit them?
Lance’s Filters are a curated set of stock filters he built and refined throughout his professional trading career, each designed to cut through market noise and surface the best day trading opportunities. Each filter includes a short description of what it does and when to use it. You cannot edit Lance’s Filters directly, but you can layer your own Global Filter on top of them to combine his criteria with your own preferences.
What is the Global Filter?
The Global Filter is an optional layer that applies to every query you run, including Lance’s Filters. It is useful for removing false positives, such as filtering out penny stocks by setting minimum price or volume thresholds. You can enable or disable it at any time from the New Filter page.
How does the StockFilters AI work?
The StockFilters AI is a built-in chat assistant trained on all the functions and indicators available in the platform. Describe what you are looking for in plain language and it will write the filter code for you, help debug queries that are not working, or explain how specific indicators function. It is one of the most practical AI trading tools available for retail traders, lowering the barrier to building sophisticated screens without needing technical expertise.
Is StockFilters a good screener for day trading?
Yes. StockFilters was built specifically with active traders in mind. Lance designed it to be the best stock screener for day trading by combining his real-world filters, fresh intraday data, and flexible query logic that lets you zero in on stocks in play quickly and precisely.
Can I customize what data columns appear in my results?
Yes. In Settings, you can add or remove the columns displayed when a filter returns results. You can also set your preferred default website so that clicking any ticker in your results opens it in the charting or news tool of your choice, such as TradingView.
Documentation and Learning
Where can I learn about available indicators and functions?
The Documentation section contains a full reference guide for all available functions and indicators. You can search for specific functions, review the variables involved, and see usage examples showing how each one is applied in a filter. It is accessible from both the Documentation page and directly within the New Filter page.
Will new features and indicators be added over time?
Yes. The StockFilters team continuously improves the platform based on user feedback. If there is a specific indicator you would like to see added, submit a request through the Tech Suggestions channel. New features, indicators, and documentation updates are released on an ongoing basis as the platform evolves to keep up with a fast-changing market.
Customer Support
What should I do if my filter is not working?
The first step is to use the StockFilters AI assistant. It can debug invalid queries, suggest fixes, and help you rewrite filter logic that is not producing results. If the issue persists, reach out through the community channels for additional support.
Where do I go if I want to suggest a new feature or indicator?
Head to the Tech Suggestions channel within the community. The StockFilters team actively reviews submissions and prioritizes additions based on what traders need most.
I am locked out or having trouble logging in. What should I do?
