A long-only single-instrument TREND-CONFIRMATION strategy on UNIUSDT perpetual futures (Binance USD-M) using the Aroon Oscillator on 4-hour bars. CRITICAL DESIGN CHOICES driven by 6+ consecutive supplementary-data failures plus mean-reversion/contrarian-short failures: (a) ZERO supplementary data dependency — pure OHLCV. (b) NOT mean-reversion (failed on alt perps), NOT contrarian short (failed on BTC funding). (c) 4H + Binance USD-M — the empirically proven verification combination. (d) NEW symbol — UNI (Uniswap) is not in the current portfolio of ADA/AVAX/BNB/BTC/DOT/ETH/LINK/LTC/SOL and it represents a distinct DeFi sector (DEX governance token), uncorrelated to the L1/L2/payments/oracle/meme alts already represented. (e) NEW mechanism — Aroon Oscillator is structurally distinct from every other in-pipeline indicator: it's NOT a channel (Donchian/Keltner), NOT volume-based, NOT MACD, NOT Supertrend, NOT a moving-average-based system (Hull/EMA/SMA crosses). Aroon (Tushar Chande 1995) measures TIME-SINCE-EXTREME rather than price-vs-MA: Aroon Up = 100 × (period − bars_since_highest_high) / period. When the most recent high is very recent AND the most recent low is far away, the trend is strongly up. This is a fundamentally different signal source. (f) MAXIMALLY SIMPLE — single meaningful parameter (Aroon period = 14, canonical Chande default).
