Port 善's explicit SuperTrend trading rules from the FMZ article, using 15-minute BCHUSDT.OKX linear perpetual bars instead of the historical BTC/USD inverse quarterly contract. Preserve period 45, factor 3, both trading directions, and exit-before-reentry behavior. Adapt the source's repeated aggressive two-tick limit orders to ordinary market orders at the signal bar's close; this preserves directional intent but does not reproduce its polling, cancellation or partial-fill timing. Replace the fixed one-contract amount with 20% of current equity in position notional, without leverage amplification. The source has no separate stop-loss, take-profit or time stop; do not add them. All six supplied figures were inspected: the cover and GitHub image add no trading rules; the comparison charts show BTC daily SuperTrend 10/3 overlays around the March 2020 decline; the parameter screenshot confirms pd=45, factor=3, Amount=1, TradeInterval=2000ms, PriceTick=0.5 and Symbol=quarter; the performance screenshot shows an unverified historical BTC/USD quarterly backtest. The trading experiment uses the article's explicit 15m and 45/3 settings, not the illustrative daily-chart settings or GitHub issue's 8/2.1 settings.
