What RSI level should I use for oversold alerts?

The classic oversold threshold is RSI below 30. More aggressive traders use 35–40 to get earlier signals before the most extreme readings. For high-beta stocks or those in strong downtrends, waiting for below 25 filters out false positives.

How is RSI calculated in Stock Alarm Pro?

Stock Alarm Pro uses a 14-period RSI, the standard Wilder smoothing method. RSI is updated in real time during market hours using the latest trade prices.

Can I set RSI alerts for ETFs and indices?

Yes. You can set RSI oversold alerts on any instrument tracked in Stock Alarm Pro — stocks, ETFs, and major indices.

How do RSI alerts work alongside price alerts?

They stack. You can have both an RSI alert (fires when RSI < 30) and a price alert (fires at a support level) on the same stock. When both fire near the same time, that's a stronger confirmation signal.

How RSI Oversold Alerts Work

The Relative Strength Index (RSI) measures the speed and magnitude of recent price changes on a 0–100 scale. Readings below 30 indicate that a stock has been sold aggressively relative to its recent history — a condition traders call "oversold."

When RSI dips under 30, it doesn't guarantee an immediate bounce, but it does signal that sellers may be exhausted. Combined with a broader uptrend, strong support level, or increasing volume, an oversold RSI reading can be one of the highest-probability long setups available.

Stock Alarm Pro monitors RSI in real time across thousands of tickers and fires a push notification the moment any stock you're watching crosses your threshold. You define the RSI level — below 30 for classic oversold, or customize to 35 or 40 for earlier signals. Pair it with a price alert at a known support level for a two-confirmation entry system.
