A LONG-SHORT, single-instrument, pure-OHLCV VOLATILITY-REGIME strategy on DOTUSDT.BINANCE USD-M perpetual. This is a deliberate MECHANISM pivot away from the momentum-confluence family that collided (and has repeatedly died overfit on XRP/BNB/AVAX/LINK/SOL-HL). Instead of requiring two timeframes to AGREE on trend direction (continuation), this detects a volatility STATE TRANSITION: when 4H Bollinger Bands contract fully INSIDE the Keltner Channels (a low-volatility 'coil' where realized range compresses below its ATR-implied envelope), volatility is mean-reverting toward expansion. The strategy stands flat during the coil and only fires on the directional break OUT of compression, taking the side of the expansion. The edge is structural and distinct from momentum: the fat left tail of realized-vol distributions means compression is followed by expansion far more reliably than price direction is autocorrelated, so the setup is a vol-regime bet with a directional overlay, not a trend-agreement bet. Kept to 3 tunable parameters (coil lookback, band width, ATR trail) to protect PBO/deflated-Sharpe. FEE ARITHMETIC: post-squeeze 4H DOT expansions historically run ~3-5% of notional over 1-3 days; the ATR chandelier captures roughly a third to a half (~1.2-1.6%, conservatively booked at 0.4% floor after slippage/partial-give-back) vs ~0.10% round-trip USD-M taker cost = ~4-15x fee coverage. Squeeze-gating fires only when compression is real, so trade count stays in the low hundreds over ~5-6 years (NOT thousands) and fee drag stays bounded - the opposite of the sub-fee VWAP/tick-churn graveyard.
