RSI measures momentum strength using price changes over a fixed period, defaulting to 14 — traders use it on TradingView to time entries by detecting reversals, divergences, and trend continuations.
RSI works on a 0–100 scale: above 70 signals overbought conditions, while below 30 signals oversold — but it works best when combined with structure and confirmation.
Start from any asset chart.
Open the indicator search panel.
Type it into the search bar.
TradingView displays it below the price chart as a separate oscillator panel.
| Setting | Default Value | Function |
|---|---|---|
| Length | 14 | Defines the calculation period |
| Source | Close | Uses the closing price |
| Bands | 30/70 | Defines the thresholds |
RSI signals entries using overbought, oversold, and midline behavior.
Example: Bitcoin’s RSI moving from 28 to 35 preceded an upward reversal within 3 candles on the 1H timeframe.
RSI divergence identifies trend reversals by comparing price action with momentum.
| Divergence Type | Pattern |
|---|---|
| Bullish divergence | Price forms lower lows, RSI forms higher lows |
| Bearish divergence | Price forms higher highs, RSI forms lower highs |
Where It Appears MostRSI divergence shows up frequently before reversals in volatile assets like crypto and forex pairs.
The default RSI length of 14 works for most traders, but adjustments can improve precision for specific styles.
| Strategy Type | RSI Length | Use Case |
|---|---|---|
| Scalping | 7 | Faster signals |
| Day trading | 14 | Balanced signals |
| Swing trading | 21 | Smoother trends |
A shorter RSI reacts faster but increases noise, while a longer RSI reduces false signals but delays entries.
You combine RSI with other indicators to confirm signals and reduce false entries.
Example strategy: RSI below 30, price touching the lower Bollinger Band, plus a bullish MACD crossover — RSI crossing back above 30 near support signals a higher-probability bullish entry.
RSI improves entry timing when it aligns with support and resistance zones.
| Condition | Signal |
|---|---|
| RSI oversold near support | High-probability buy |
| RSI overbought near resistance | High-probability sell |
Example: ETH hitting a support level with an RSI of 28 signals a strong bounce probability.
Establish overall direction first.
Let the oscillator reach its extreme zone.
Check support or resistance alignment.
Wait for the candle close confirmation.
Place it below or above the nearest structure.
RSI works across all timeframes, but reliability generally increases with higher timeframes.
| Timeframe | RSI Length | Use Case |
|---|---|---|
| 1–5 min | 7–9 | Scalping |
| 15–60 min | 14 | Intraday |
| 4H–1D | 14–21 | Swing trading |
Swing traders often prefer the 4H and daily RSI because of reduced noise and clearer trends.
Use a moving average for direction.
Locate the key price zones.
Apply the default setting to the chart.
Let a clear signal develop.
Use MACD or Bollinger Bands to confirm, then execute based on price action.
Open your chart, click Indicators, search RSI, and select Relative Strength Index — it appears below the price chart as a separate oscillator panel.
Above 70 signals overbought conditions and below 30 signals oversold conditions, both indicating a potential reversal zone.
It’s when price and RSI move in opposite directions — bullish divergence is lower price lows with higher RSI lows, and bearish divergence is the reverse.
The default length of 14 is balanced for day trading; scalpers often use 7 for faster signals, and swing traders use 21 for smoother trends.
No. RSI works best combined with trend direction, support/resistance, or other indicators like MACD to confirm the signal and reduce false entries.
