BNB Daily Funding-Rate Percentile Long with 200-SMA Regime Filter

A long-only single-instrument carry-and-direction strategy on BNBUSDT perpetual futures using daily bars + funding-rate data. This proposal directly responds to the analyst recommendation after the BNB Daily Multi-Week Trend abandonment: 'Stop attempting BNB daily long-only trend strategies until/unless a fundamentally different signal mechanism is proposed (e.g., funding-rate or open-interest based, not price-only).' This is a NEW mechanism class using REAL funding-rate data — not a price-only construction. The thesis: when BNB perp funding is in the bottom 30% of its trailing 90-day distribution (RELATIVE percentile, NOT an absolute threshold) AND BNB is above its 200-day SMA, market positioning is bearish-skewed (low funding = shorts not paying longs much, leveraged longs absent) WHILE the long-term trend is intact. This combination historically resolves with bullish catch-up rallies as the negative-positioning unwinds. Importantly, this proposal explicitly addresses the recently-documented failures: (a) NOT a price-only mechanism — uses funding rates as primary trigger, exactly what the analyst recommended after BNB Multi-Week Trend failure, (b) NOT an architecture-clone — uses RELATIVE percentile (rolling distribution) rather than the absolute negative-funding threshold that doomed BTC Negative Funding Carry (its trigger condition disappeared as crypto markets matured; relative percentile self-adapts to current funding-rate regime), (c) NOT a multi-condition AND-gate — single dominant signal (funding percentile) + single regime filter (200-SMA), (d) NO bait-and-switch — strictly BNBUSDT.BINANCE perp throughout, (e) sensitivity_passed=true with cliff_count=0 REQUIRED before optimization. BNB-SPECIFIC empirical justification: BNB has Binance-ecosystem catalysts (Launchpad, burns, BNB Chain news) that produce the most dynamic funding-rate flows of any crypto major — funding spikes around Launchpad events, burn quarters, and BNB Chain DeFi launches. The relative percentile filter captures these regime extremes. Existing BNB strategy in pipeline (BnbFourHourVolumeBreakoutLong) uses 4H + price/volume. This uses daily + funding. Genuinely orthogonal data source and timeframe.
