Why “RSI below 30” is a bad scan
The Relative Strength Index measures how far recent gains outweigh recent losses on a 0–100 scale. The textbook rule — buy under 30, sell over 70 — fails in crypto because strong trends stay overbought for days and weak coins stay oversold all the way down. A raw “RSI < 30” scan mostly returns coins that are falling for a reason.
RSI works much better as a timing tool inside a trend: find coins whose higher timeframe is up, then wait for a short-term RSI dip. That is what the scans below do.
RSI settings that matter
- Length — 14 is standard. Short lengths like RSI(2) or RSI(5) react within a few candles and suit pullback scans; long lengths smooth out noise.
- Timeframe — each condition can use its own: a daily trend filter with a 1h RSI trigger is one scan.
- Thresholds — in uptrends, dips often hold around 40 rather than reaching 30. Bull-market “oversold” is higher than the textbook number.
- Crosses — “RSI crosses above 50” catches the moment momentum flips, not every bar it stays above.
Ready-to-use RSI scans
RSI 50 cross on the hour (Free)
Momentum turning up while price is above its long-term average. Two conditions on 1h — this works on the free plan.
Oversold dip in a daily uptrend
A strong daily trend with a sharp two-day dip. Classic short-term mean-reversion setup; needs the daily timeframe (Premium).
Multi-timeframe RSI alignment
Higher timeframes already strong, lower timeframe just turning — entries in the direction of the bigger move.
Overbought into resistance
Stretched momentum right at last week’s high — a watchlist for exhaustion, not an automatic short.
RSI is free in CryptoScanX, on the 15m and 1h timeframes with up to two conditions. Premium adds every timeframe from 1 minute to monthly, up to 10 conditions and alerts. See how multi-timeframe scans work.
Frequently asked questions
What is the best RSI setting for crypto?
RSI(14) is the standard and works for most scans. For pullback entries many traders use a short RSI(2)–RSI(5) on the daily or 4h chart, filtered by a long-term trend such as the 200-day moving average.
Is the RSI scanner free?
Yes. RSI is a free indicator in CryptoScanX on the 15m and 1h timeframes, with up to two conditions per scan. Premium ($3.99/month globally, ₹99/month in India) unlocks all timeframes, 10 conditions and alerts.
Can I get an alert when RSI crosses a level?
Yes, with Premium. Save a scan such as “1h RSI(14) crosses above 50” and turn on alerts; you get a push notification when a coin newly matches.
