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.
