Mean Reversion

Use when writing a Bollinger-band mean-reversion strategy on Superior Trade — anything described as mean reversion, BB bands, oversold bounce, fade, range trade, ADX low, sigma extension. Upgraded 2026-05-18 from the prior 1h/2.5σ variant to the validated 4h/2σ/ADX<25 version (+8.77% multi-pair, 65.5% win over 162d). Prior 1h variant is preserved at the end of the file as an archived reference.

Mean Reversion — Bollinger Reverter 4h

Note: This template was upgraded from the prior 1h / 2.5σ / ADX<30 version to the 4h / 2σ / ADX<25 version after backtesting showed the 4h variant produces meaningfully more trades with comparable risk and validated multi-pair edge. The prior 1h version is preserved at the end for reference.

---

Symmetric mean-reversion strategy on the 4h timeframe. Long-or-short on Bollinger band touches, gated to range regimes via ADX. Validated across BTC/ETH/SOL/DOGE over 162 days.

Backtest evidence

Config	Trades	Win	Profit	Max DD
BTC/USDC:USDC, 162d	18	72%	+8.14%	10%
BTC/USDC:USDC, range-regime sub-window (80d)	8	100%	+9.88%	0%
BTC/ETH/SOL/DOGE multi-pair, 162d	84	65.5%	+8.77%	18.5%

Thesis

When the market is range-bound (ADX < 25), price touching the upper or lower Bollinger Band reliably reverts to the midline. Tight ROI takes profit fast since mean-reversion targets are small; tight stop closes positions that turn into trend breaks rather than reversions.

Mechanics

• Timeframe: 4h
• 20-bar Bollinger Bands at 2σ
• Entry short: close > bb_upper AND rsi > 65 AND adx < 25
• Entry long: close < bb_lower AND rsi < 35 AND adx < 25
• Exit: close crosses the band midline
• Stop: -2%
• ROI ladder: 2.5% → 1.5% → 0.5% → breakeven over 24h
• No trailing stop (band reversion targets are small; ROI ladder handles take-profit)

Honest framing

In strong-trend windows the strategy loses small (-1.75% on BTC during the first-half strong bear). In rangy windows it shines (+9.88% on BTC second-half). The mixed-regime full-period multi-pair number (+8.77% in 162d on $350 wallet) is the credible expectation.

DOGE was the negative pair (-0.65%) — meme volatility breaks more bands than reverts to them. Use this strategy on majors.

Pair with donchian-strong-regime for full-regime coverage.

Prior version (1h, 2.5σ, archived)

The previous version was tighter (2.5σ bands, ADX<30) on a 1h timeframe. Its own honest framing noted "5 trades in 4 months" — too rare to be useful. The 4h version produces ~3× the signal density with the same risk profile. The 1h version is preserved here for users who want a deeper-fade variant:

python

# Archived 1h variant — fewer, deeper signals
timeframe = "1h"
# bb = ta.BBANDS(dataframe, timeperiod=100, nbdevup=2.5, nbdevdn=2.5)
# rsi gates same; adx < 30 (looser)

If you prefer the rarer-but-deeper setup, restore the 1h timeframe and 2.5σ. The exit logic is unchanged.
