A long-only, single-instrument, single-timeframe strategy on ADAUSDT.BINANCE 4H bars implementing the analyst's EXPLICITLY RECOMMENDED structural mechanism: N-BAR INSIDE-BAR CLUSTER BREAKOUT. From the most-recent ADADoubleLowSupportReclaim abandon feedback: 'try a different structural mechanism (e.g., volatility-contraction-then-expansion, range-compression-breakout, or N-bar inside-bar-cluster)'. The mechanism: detect a sequence of 3+ consecutive INSIDE BARS (each bar's high <= prior bar's high AND each bar's low >= prior bar's low — i.e., each bar's range is CONTAINED within the prior bar's range). This signals progressive volatility contraction — a 'coiled spring' as ranges narrow toward equilibrium. When the contraction resolves with a breakout above the highest high of the inside-bar cluster, and the broader trend filter holds, enter long. Range-compression-breakout is a documented structural pattern (Crabel 1990 'Day Trading with Short-Term Price Patterns' formalized inside-bar concepts) — when ranges contract toward a point, the subsequent expansion is statistically biased toward the broader trend direction. Critically distinct from every existing ADA 4H mechanism: (a) NOT Donchian breach (uses bar-RANGE containment, not channel extremes); (b) NOT channel-width expansion (uses INSIDE bar sequence, not channel width metric); (c) NOT support-level patterns (uses range geometry not price levels); (d) NOT statistical signals (z-scores, autocorrelations failed); (e) NOT single-bar geometry (multi-bar sequence). SEQUENCE-BASED + RANGE-STATISTICS per analyst's explicit successful-pattern profile.
