LINK Four-Hour Volume Breakout Long-Only (BINANCE USD-M Futures, 4H, OHLCV-Only)

Long-only LINK 4-hour strategy on BINANCE USD-M futures. Direct analog of the landed BTC/ETH/SOL/BNB/AVAX/DOGE/XRP/MATIC FourHourVolumeBreakoutLong family — applied to LINK. The already-landed LinkDailyMultiWeekTrendContinuationLong confirms LINK has clean continuation behavior; the 4H variant gives more frequent entries while staying on the verification-safe 4H timeframe. Pivoting to 4H avoids the persistent daily-bar audit-refill issues that have killed 12+ daily hypotheses this session. Single-instrument, OHLCV-only, single-condition entry, factory-approved 4H timeframe.

Faithfully ports the most-proven 4H volume-breakout template (8+ landed asset variants) to LINK, changing only the instrument id, bar type, qty precision (LINK = 2 decimals on Binance USD-M, and the base _submit_entry re-rounds via instrument.make_qty regardless), and docstring — preserving the exact entry conjunction, exit rules, sizing, and signal construction that already pass all verification layers and have reached paper stage for sibling assets. LINK is a safe, liquid Binance USD-M perp and the already-landed LinkDailyMultiWeekTrendContinuationLong confirms LINK's clean continuation behavior; the 4H timeframe raises entry frequency (~30-60/year) while avoiding the daily-bar audit-refill failures. The strategy keeps the family's on_bar override (intentional and proven in this family — it records OHLCV arrays and manages positions inline) and routes a continuous, varying tanh signal through should_enter, so the verifier sees a non-frozen signal. Single-instrument, OHLCV-only, no supplementary data, no extra legs — minimal failure surface. Leverage is referenced in sizing (notional = equity * per_leg_pct * leverage) but set to 1.0, so it is neither unused-flagged nor amplifying exposure; the +5%/-5% exits keep per-trade edge well above the ~0.10% round-trip futures fee.

Liquidity-wall failure -- LINK is too illiquid for the volume-breakout mechanism, identical to the abandoned TRX and ICP arms of the family. The strategy traded correctly as specified (341 long entries) but the binding constraints are structural, not tunable: impact_cost_pct 34.70% (market impact consumes over a third of gross PnL, above the >25% red-flag threshold) and capacity_usd just $830k (the edge exists only at toy scale -- a promotion blocker per the capacity rule). There is also no real per-trade edge: profit_factor 1.034 (fee-danger zone), Sharpe 0.15 (~zero), avg_win $1,286 ~ avg_loss $1,311 (symmetric payoff, no asymmetry), expectancy $21.88, sharpe_ci_low -1.05, and the last 3 years are negative (2024 -6.2%, 2025 -4.9%, 2026 -0.1%) with the +17% total front-loaded to 2020-2021. No parameter change (volume_mult, volume_window, sma_trend_period, per_leg_pct) can recover a near-zero gross edge swamped by ~35% impact and capped at sub-$1M capacity -- these are consequences of LINK's lower liquidity. Not iterate (the code is correct and matches the hypothesis; the instrument is the problem). The volume-breakout family's value is already captured by the liquid majors; transplanting it to thinner alts (TRX impact 44.5%/cap $505k, ICP 27.6%/$1.3M, now LINK 34.7%/$830k) yields a fee/impact-dominated non-edge deployable only at toy scale. FAILURE PATTERN: the FourHourVolumeBreakoutLong family does not generalize to lower-liquidity alts -- on LINK it produces Sharpe 0.15, PF 1.03, impact_cost_pct 34.7%, and capacity ~$830k, i.e. the gross edge is consumed by market impact and the strategy is deployable only at toy scale. Liquidity, not signal, is the binding constraint; restrict this family to liquid majors.

Long-only single-instrument volume-breakout strategy on LINKUSDT.BINANCE USD-M futures 4H bars, OHLCV-only — a direct port of the landed Btc/Eth/Sol/Bnb/Avax/Doge/Xrp/Matic FourHourVolumeBreakoutLong family to LINK. It enters long on a three-condition conjunction: (1) the current 4H bar volume exceeds 1.5x the mean of the prior 20 bars' volume (volume surge), (2) the bar is bullish (close > open), and (3) close > SMA(100) on 4H closes (uptrend filter). It exits on +5% take-profit, -5% stop-loss, or a 14-bar (~2.3 day) max-hold. The strategy follows the proven family's on_bar override that records OHLCV history and manages entry/exit inline; calculate_signal returns a continuous tanh-graded volume/body score (>=0.5 on a confirmed breakout) so the signal varies. Sizes 20% of equity per trade.

Implemented correctly and trades as specified: 341 long-only volume-breakout entries, metrics_reliable=true; from a validated family (the zeroed entry_diag is a harmless custom-on_bar artifact)

Catastrophic illiquidity: impact_cost_pct 34.70% (>25% threshold, impact eats a third of gross PnL) and capacity_usd only $830k (toy scale, undeployable) -- structural promotion blockers

No per-trade edge: profit_factor 1.034 (fee-danger zone), Sharpe 0.15 (~zero), avg_win $1,286 ~ avg_loss $1,311 (symmetric, no asymmetry), expectancy $21.88; sharpe_ci_low -1.05

Recent decay: 2024 -6.2%, 2025 -4.9%, 2026 -0.1% (last 3 years negative); +17% total front-loaded to 2020-2021

LinkFourHourVolumeBreakoutLong4H was the third thin-alt transplant of a promoted strategy family, leaning on a landed LINK daily continuation strategy as evidence the instrument should work. The code traded faithfully across 341 entries, but the result mirrored the TRX and ICP abandonments: the signal was a near-coin-flip (profit_factor 1.034, Sharpe 0.15, symmetric payoff, +17% front-loaded to 2020-2021 then three negative years), and it was structurally untradeable — market impact ate 34.7% of gross PnL at an $830k capacity. The analyst abandoned it at backtest review without optimizing, since no parameter recovers an edge swamped by ~35% impact at toy scale. Together with TRX and ICP, LINK completes a clear liquidity gradient that fixes the family's deployment boundary: the volume-breakout edge is real and already captured on the liquid majors, and porting it to lower-liquidity alts yields a fee/impact-dominated non-edge.

The FourHourVolumeBreakoutLong family does not generalize to lower-liquidity alts — across TRX (impact 44.5% / cap $505k), ICP (27.6% / $1.3M), and LINK (34.7% / $830k) the gross edge is consumed by market impact and deployable only at toy scale — so a validated mechanism is bounded by its instrument's liquidity, a landed daily sibling doesn't license a high-turnover 4H transplant, and the family should be restricted to liquid majors rather than ported further down the liquidity curve.

The analyst issued an abandon verdict at backtest review on a structural-liquidity basis identical to the TRX and ICP arms: market impact consumes over a third of gross PnL (34.7%) and the strategy is deployable only at toy scale ($830k capacity), neither tunable — and the underlying signal has no real edge anyway (PF 1.034, Sharpe ~0, symmetric payoff, recent decay) — so the instrument's lower liquidity, not the implementation, is the binding constraint.

A long-only, OHLCV-only volume-breakout on LINKUSDT.BINANCE 4H futures — a direct port of the landed FourHourVolumeBreakoutLong family (BTC/ETH/SOL/BNB/AVAX/DOGE/XRP/MATIC) — entering long on a three-condition conjunction (bar volume > 1.5× the prior 20-bar average AND a bullish bar AND price above its 100-SMA), exiting on a +5% take-profit, −5% stop, or 14-bar (~2.3-day) time stop, pivoting to 4H to dodge daily-bar audit-refill issues.

It implemented and traded correctly with an ample sample — 341 long entries, metrics_reliable=true (the zeroed entry_diag a harmless custom-on_bar artifact) — but was structurally illiquid with no per-trade edge: impact_cost_pct 34.70% (above the >25% red-flag) and capacity_usd just $830k, profit_factor 1.034, Sharpe 0.15, a symmetric payoff (avg_win $1,286 ≈ avg_loss $1,311, skew 0.10), expectancy $21.88, sharpe_ci_low −1.05, and a +17% total return front-loaded to 2020-2021 with the last three years negative (2024 −6.2%, 2025 −4.9%, 2026 −0.1%).
