Mean Reversion & FadesPRO

Triple Oversold Reversal

The strongest mean reversion signal in QSA. Fires when three independent indicators agree: RSI below 20, price below the lower Bollinger Band, AND price below the lower Keltner Channel. Requires a bullish reversal candle (hammer, doji, or engulfing) for confirmation. Combines the old Oversold Bounce and Keltner Mean Reversion scanners into one high-conviction signal.

What is this scanner?

The Triple Oversold Reversal is QSA's highest-conviction mean reversion signal. It fires only when three independent indicators simultaneously confirm extreme oversold conditions: RSI below 20, price below the lower Bollinger Band, AND price below the lower Keltner Channel. When all three agree, it represents a statistically rare confluence that has strong historical reversal probability.

This scanner combines the old Keltner Mean Reversion and Oversold Bounce scanners into a single, stricter signal. The triple confirmation requirement dramatically reduces false positives compared to using any one indicator alone.

Origin & History

Each of the three components has independent origins: RSI from J. Welles Wilder (1978), Bollinger Bands from John Bollinger (1983), and Keltner Channels from Chester Keltner's work popularized in the 1960s. The combination of all three — specifically requiring price to be below all three lower bands simultaneously — was a synthesis developed by algorithmic traders looking for high-precision reversal filters.

The theoretical basis is that each indicator captures a different dimension of oversold condition: RSI measures momentum exhaustion, Bollinger Bands measure volatility-relative extremity, and Keltner Channels measure ATR-relative extremity. When all three are triggered, the probability of a sustained continuation lower drops sharply in historical backtests of crypto perpetuals.

Detection Criteria

RSI Extreme

14-period RSI drops below 20 — the most extreme oversold reading, representing the bottom 5% of all RSI values in normal market conditions.

Bollinger Band Violation

Price closes below the lower Bollinger Band (2 standard deviations). This indicates price is more than 2 standard deviations below the 20-period mean.

Keltner Channel Violation

Price closes below the lower Keltner Channel (typically 1.5x ATR below the EMA). This confirms the extreme using an ATR-based measure, independent of volatility skew.

Reversal Confirmation Candle

A bullish reversal pattern (hammer, doji, or bullish engulfing) on the most recent candle or within the last 2 candles. This is the trigger — without it, extreme readings are just extremes.

Grading Breakdown

S

All three indicators below their thresholds with RSI below 15 (extreme of the extreme) and a strong bullish engulfing candle on above-average volume. Rare and very high probability.

A

Full triple confirmation with RSI 15-20 and a clear reversal candle (hammer or doji) on average or above-average volume.

B

RSI and one of the band indicators confirmed, but the third is only marginally violated. Still a strong signal but not the full triple.

C

Two of three indicators at extreme but the third hasn't breached its threshold. Monitor — if the third confirms, grade will upgrade automatically.

Common Mistakes

✕

Entering during a sustained downtrend assuming the triple confirmation means the bottom. Even with triple oversold, trends can persist — check the regime and whether higher timeframe structure is broken.

✕

Not waiting for the reversal candle. Triple oversold without a reversal candle is an extreme in motion, not a reversal. The candle is the entry trigger.

✕

Using this scanner on very short timeframes (5m, 15m) where RSI and band extremes are noisy. Best results on 1h and 4h.

✕

Averaging down on a failed triple oversold. If the reversal candle fails and price makes new lows, the triple oversold signal is no longer valid — exit and reassess.

How to Trade

▲

Entry Context

Enter on the close of the reversal confirmation candle. Do not enter before the candle closes — the confirmation is what validates the signal. If volume is above average on the reversal candle, increase conviction.

■

Risk Management

Stop below the lowest wick of the triple oversold candles (the absolute extreme). This is the hard invalidation level. Risk 1-2% of portfolio. If price makes a new low after your entry, exit immediately.

Target Framework

First target: middle Bollinger Band (20-period SMA). Second target: upper Keltner Channel. These represent a full mean reversion. Take 50% off at the first target and trail the remainder.
