Strategy research profile

Strategy overview

A prior day's unusually narrow range defines the setup. A subsequent daily close beyond its high or low determines the target; the benchmark does not assume that intraday stop orders filled exactly at those boundaries.

Source attribution and native timeframe are transcribed only from hash-matched reviewed source text. These are source example/declaration values, not verified authorship or the timeframe of this benchmark.

Theoretical basis

A completed close beyond a range or volatility boundary is treated as continuation or expansion. The boundary is calculated from information available at the decision bar.

Market-regime hypothesis

Expansion after compression or movement beyond a prior range.

DuckQuant editorial interpretation of the rule. These mechanisms and regime expectations are hypotheses, not independently established explanations of the measured returns.

Risks and failure modes

False breaks, gap execution, late entries and mean-reverting markets can produce losses; closing-price confirmation does not guarantee a fill at the boundary.

A retrospective two-year window and ETF proxy choices do not establish general robustness.
Daily-open fills omit order-book depth, lot constraints, taxes and intrabar stop behavior.
Related rules and identical execution paths are not independent evidence.

Exact rule

Previous day is narrowest of seven; close above that high enters. A close below the setup low exits. No intraday stop fills.

Indicators and rule tokens

All thresholds, lookbacks and timing conventions are specified in the exact rule above and the downloadable adapter. Source platform settings do not override this frozen benchmark rule.

Reading and theoretical references

Published rule or indicator reference; adaptation is described separately.

Adaptation and interpretation

Daily closed-bar signals, next-open all-in long/cash, fixed fees/slippage. Short entries become cash. Source risk sizing, intraday orders, ROI, TP/SL, trailing stops, pyramiding, sessions and protections are NOT native replicas unless explicitly implemented in the stated rule. Source conflict signals resolve to cash. Common indicators are not certified TA-Lib/Pine identical. This teaching source supports the named strategy or indicator. The exact finite entry/exit convention in this record is the DuckQuant reference interpretation, not certification of a full original trading system. For indicator-only sources no claim of a complete published strategy is made.

These are normalized daily long/cash rule tests. They do not reproduce every original platform order, risk control or indicator initialization. Indicator-rule references are explicit interpretations of teaching documentation, rather than complete original published systems.

Asset cohorts rank independently by net daily Sharpe. Annual subtests restart in cash; cost stress doubles fees and slippage.

Metric definitions and unavailable statistics

annualized volatility: Sample standard deviation of daily equity returns, including initial cash, multiplied by sqrt(365) for crypto or sqrt(252) for ETFs.
sortino: Mean daily return / sqrt(mean(min(return,0)^2)) × sqrt(asset annualization sessions); minimum acceptable daily return 0; N/A without downside.
calmar: Evaluation CAGR / absolute evaluation maximum drawdown; N/A with zero drawdown.
relative return pp: Strategy total net return minus same-asset buy-and-hold total net return, in percentage points; not factor-adjusted alpha.
cost drag pp: Base net return minus doubled-cost net return, in percentage points.
longest underwater days: Longest observed calendar duration from a daily equity peak until a later below-peak close, including initial cash. Unrecovered runs are censored at sample end; closed-market days between observations count as calendar time.
monthly returns: Continuous account month-end equity change from preceding month-end (initial cash for first month); differs from yearly cash-restart subtests.

Orders are entry/exit operations. Round-trip win rate, profit factor and trade-level holding periods are not available in the stored run and are not estimated.

Primary coverage: BTCUSDT, GLD gold ETF and QQQ Nasdaq-100 ETF; ETH is supplementary. ETF prices are raw traded USD OHLCV. Dividend entitlements accrue for prior-close holders and settle on official payment dates; paid dividends remain cash until a later entry, with no automatic reinvestment. Sharpe uses 252 ETF sessions or 365 crypto days. CAGR uses 731 calendar days. Gold spot and the Nasdaq-100 index are represented by traded proxies; USD and USDT are not FX-normalized.
