In this lesson, you will learn how to use screeners to find trading setups without guessing. You will see what filters matter, how to combine them, and how to turn a screener result into a trading plan.
What a Stock Screener Does
A <strong>stock screener</strong> is a tool that searches the market using rules you choose. Instead of looking through hundreds or thousands of charts one by one, you can filter stocks by price, volume, trend, volatility, earnings, sector, and many other conditions.
Screeners do not tell you what to buy. They help you build a focused watchlist. The real trading decision still comes from chart review, risk management, and your trading plan.
For intermediate traders, stock screener trading is useful because it brings structure to the search process. You are not asking, “What looks interesting today?” You are asking, “Which stocks match my setup rules today?”
Common screener filters include:
The goal is not to add every filter possible. The goal is to filter for the specific behavior you want to trade.
Build Filters Around a Setup, Not Around Hope
Before opening a screener, define the setup. A <strong>setup</strong> is a repeatable group of conditions that may create a trading opportunity. A good setup has clear entry ideas, invalidation levels, and risk limits.
Here is an example of a trend continuation setup:
Possible screener filters:
This type of scan can find stocks that are already strong and attracting volume. That does not mean you buy them immediately. It means they deserve chart review.
Here is a different example: a pullback setup in an uptrend. A <strong>pullback</strong> is a temporary move lower within a larger upward trend.
Possible filters:
This scan looks for stocks that are still in a larger uptrend but have cooled off. The next step is to check whether the pullback is orderly or whether the stock is breaking down.
If you search “how to use stock screener,” remember this rule: start with the trade idea first, then build filters to match it. Do not start with random filters and then invent a reason to trade the result.
Practical Screener Examples
Many traders use tools such as Finviz, TradingView, MarketSmith, StockCharts, or broker-based scanners. Finviz is popular because it is simple and has many filters. Finviz screener trading often starts with three groups of filters: descriptive, fundamental, and technical.
<strong>Descriptive filters</strong> describe the stock itself. Examples include sector, industry, market cap, price, and average volume.
<strong>Fundamental filters</strong> describe the business. Examples include earnings growth, sales growth, profit margin, and debt levels. Swing traders may use these to avoid weak companies, while day traders may care more about volume and price movement.
<strong>Technical filters</strong> describe price action. Examples include moving averages, new highs, RSI, performance, volatility, and chart patterns.
Example 1: Breakout watchlist
A <strong>breakout</strong> happens when price moves above a clear resistance level. <strong>Resistance</strong> is an area where sellers have previously stopped price from rising.

Example 2: Gap-up momentum scan
A <strong>gap</strong> happens when a stock opens much higher or lower than the previous closing price. Gaps often occur after earnings, news, analyst upgrades, or market-moving events.

Example 3: Mean reversion scan
<strong>Mean reversion</strong> is the idea that price may move back toward its average after becoming stretched. This is different from breakout trading because you are looking for overextension, not strength continuation.

Turn Screener Results Into a Trade Plan
A common mistake is treating screener results as buy signals. A screener only gives candidates. After the scan, you still need a plan.
Use this process:
1. <strong>Run the scan after the market close or before the open.</strong> This gives you time to think instead of reacting.
2. <strong>Review charts manually.</strong> Remove stocks with messy price action, wide spreads, or unclear levels.
3. <strong>Mark key levels.</strong> Identify support, resistance, possible entry, stop loss, and target areas.
4. <strong>Check upcoming events.</strong> Earnings, economic reports, regulatory news, and company announcements can change risk.
5. <strong>Size the trade based on risk.</strong> Decide how much you are willing to lose if the trade fails.
For example, suppose your breakout scan finds a stock trading at $48 with resistance at $50. The chart shows rising volume and higher lows, meaning buyers are stepping in at higher prices. You might plan an entry above $50.25 if the breakout holds. If support is near $47.80, your stop could be below that level. If you risk $1.25 per share and your account risk limit is $250, your position size would be 200 shares. This is position sizing based on risk, not excitement.
Also consider market context. A strong setup has better odds when the overall market and sector are moving in the same direction. If a technology stock is breaking out while the technology sector is weak, be more careful.
