Derived by the Research Lead from the FMZ essay on falsifiable trading decisions and avoiding additions to losing positions: https://www.fmz.com/bbs-topic/973. The supplied local article was read; it supplies a philosophy of explicit invalidation, not these entry rules. This operationalization tests whether a completed spot breakout followed by a successful later retest of its frozen boundary predicts multi-day continuation. Use synchronized 4-HOUR bars for three independent spot/perpetual pairs. Trade only Hyperliquid perps, both long and short; Binance spot instruments are signal sources. No trade occurs on the initial breakout. Market orders execute at the completed confirmation bar close, the capability registry equivalent of next-bar-open execution on continuous venues. Intrabar protective stops are matched by the platform, with no exchange-hosting requirement. Baselines: range_bars=30, retest_window_bars=12, retest_band_atr=0.35. Predicted frequency is 12-24 completed campaigns per asset/year, not a measured rate. Use all actual overlapping history, with no assumption that Hyperliquid 4H history can be backfilled indefinitely.
