RSI Signal Interpretation
Quick-reference guide to 6 signal types you will see on the chart.
| Signal Type | Indicator Condition | Market Meaning | Reliability |
|---|---|---|---|
| Overbought (>70) → Sell | RSI crosses above 70 then drops back below 70 | Price has moved up too fast. Expect pullback or reversal. Stronger signal when RSI stays below 70 after the drop. | 3/5 |
| Oversold (<30) → Buy | RSI crosses below 30 then rises back above 30 | Price has sold off excessively. Bounce or reversal likely. Most reliable in range-bound markets. | 3/5 |
| Bullish Divergence → Buy | Price makes lower low, RSI makes higher low | Downward momentum is weakening. Reversal to the upside incoming. One of the most reliable RSI signals. | 5/5 |
| Bearish Divergence → Sell | Price makes higher high, RSI makes lower high | Upward momentum is stalling. Reversal to the downside likely. Works best after extended trends. | 4/5 |
| Centerline Cross (50) | RSI crosses above or below the 50 level | Above 50 = bullish momentum, below 50 = bearish momentum. Used as trend filter rather than entry signal. | 4/5 |
| Failure Swing → Reversal | RSI crosses below 30, bounces above 30, pulls back above 30, then breaks above the bounce high | Classic bullish failure swing. Momentum has shifted and the downtrend is exhausted. | 4/5 |

Parameter settings tested across different market conditions and timeframes.
| Parameter | Default | Description |
|---|---|---|
| RSI Length | 14 | Lookback period. Lower values (7-9) create more signals for scalping. Higher values (21) filter noise for swing trading. |
| Source | Close | Price source. Close gives standard RSI. HLC3 for smoother readings on volatile markets. |
| Overbought Level | 70 | Threshold above which RSI is overbought. Tighten to 80 for strong trends, loosen to 65 for range markets. |
| Oversold Level | 30 | Threshold below which RSI is oversold. Tighten to 20 for strong downtrends. |
