ETH 1H UTC Opening Range Breakout Long with ATR Trailing Stop

Hypothesis

A long-only single-instrument session-based breakout strategy on ETHUSDT perpetual futures using 1-hour bars. At each UTC day rollover (00:00 UTC), the strategy defines an 'opening range' from the first 4 hourly bars (00:00-04:00 UTC). Once the range is locked, the strategy waits for a confirmed breakout above the range high by a small ATR buffer and goes long. Exits use a chandelier-style ATR trailing stop, a fixed 2R take profit, and a hard end-of-day flat (23:00 UTC) so positions never carry across the next session's range definition. Only OHLCV data, only 3 parameters (range_hours, atr_period, atr_trail_mult). Deliberately distinct from every recent failure pattern: not 1D, not 4H, not contrarian, not funding-driven, not pairs, not OI/liquidations-driven, not a SMA crossover or RSI(2) pullback. Verification surface is intentionally tiny — no supplementary data, no extra_bar_types, no extra_instruments — to avoid the synthetic-data injection paths that have been correlated with verification timeouts.
