**Application 1: RSI Divergence (Strongest Signal)**
RSI divergence occurs when price and RSI disagree — price makes a new high but RSI makes a lower high (bearish divergence), or price makes a new low but RSI makes a higher low (bullish divergence).
Why it works: divergence reveals that the momentum behind a price move is weakening before price itself reverses. Institutions begin distributing into strength (bearish divergence) or accumulating into weakness (bullish divergence), and RSI captures this divergence in momentum before it appears in price.
Bearish divergence reliability is significantly higher when it occurs after a prolonged uptrend (50+ bars) and at a known resistance level. Bullish divergence is most reliable in a downtrend at known support. Per Colby (2003), RSI divergence generates roughly 67% accuracy in these conditions versus approximately 48% for standalone overbought/oversold signals.
**Application 2: RSI Trend / 50-Level Filter**
RSI staying above 50 indicates that recent price action is dominated by gains — a useful filter for confirming an uptrend. RSI staying below 50 confirms a downtrend.
Using RSI-50 as a trend filter:
- Only take long setups when RSI is above 50 on the entry timeframe AND the higher timeframe
- Only take short setups when RSI is below 50 on both
- When RSI crosses 50 with momentum (fast move through), treat it as a trend change signal
This simple filter eliminates a large percentage of counter-trend entries that look good on the chart but fade quickly.
**Application 3: RSI Failure Swing**
This is Wilder's own preferred RSI application, largely forgotten in favor of the simpler overbought/oversold method.
A bullish failure swing:
1. RSI falls below 30
2. RSI bounces above 30
3. RSI pulls back but stays above 30 (higher low)
4. RSI breaks above the prior bounce high
The breakout of the RSI pattern — not the initial oversold reading — is the signal. This confirmation step dramatically reduces false positives compared to simply entering when RSI hits 30.
