Free Oversold Stock Screener & Reversal Scanner

How to Scan for Oversold Stocks

Scanning for oversold stocks traditionally requires monitoring dozens of technical indicators across thousands of charts — a tedious and error-prone process. Most traders rely on a simple RSI below 30 rule, but this approach generates countless false signals because it ignores the duration of the oversold condition.

Our free oversold stock screener automates this entire process using the proprietary XTRM algorithm. Instead of just checking if RSI is below a threshold, XTRM calculates the cumulative time an asset has spent in extreme territory. The more negative the XTRM score, the more exhausted sellers are — and the higher the probability of a snap-back reversal. We scan both daily and weekly timeframes across stocks and crypto to surface the 50 most extreme setups every single day.

Why Traditional RSI Screeners Give False Signals

The Relative Strength Index (RSI) is the most popular oversold indicator, but using it as a binary screener filter is deeply flawed. Here's why:

• RSI measures velocity, not exhaustion. A stock can drop quickly (triggering RSI below 30) and continue falling for weeks. RSI says "oversold" but the selloff has barely begun.
• RSI resets too quickly. A minor bounce pushes RSI back above 30, removing the stock from your screener — even if it's about to make new lows.
• RSI ignores context. A stock that has been oversold for 2 days is fundamentally different from one that has been oversold for 20 days, but both show the same RSI reading.

The XTRM duration model solves these problems by tracking how long conditions persist. A score of −50 (mildly oversold for a short time) is very different from −300 (extremely oversold for an extended period). This distinction is what separates noise from high-probability setups.

Automating Your Stock Scanning

Even the best screener requires you to check it daily. And in fast-moving markets, the most extreme setups can appear and resolve within hours. That's why we built real-time email alerts on top of our screener.

When our XTRM algorithm detects that an asset has reached a point of exhaustion and shows early signs of reversal, we send you an email alert with the exact entry level, support zone, and XTRM score. It's like having the screener run 24/7 and tap you on the shoulder only when something truly extreme happens.

Stop refreshing screeners and manually scanning charts. Subscribe to our free alerts and let the algorithm do the work for you.

XTRM Score Levels

• 0 to −99: Mildly oversold — entering oversold territory
• −100 to −149: Moderately oversold — sustained selling pressure
• −150 to −199: Heavily oversold — significant downward momentum
• −200 and below: Extremely oversold — point of exhaustion
