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

Long-only OP (Optimism) 4-hour strategy on BINANCE USD-M futures. Direct analog of the landed BTC/ETH/SOL/BNB/AVAX/XRP (Sharpe 1.84 just confirmed at risk_review)/APT/ICP/ARB FourHourVolumeBreakoutLong family — applied to OP. Pivoting to 4H avoids daily-bar audit-refill issues. Single-instrument, OHLCV-only, single-condition entry, factory-approved 4H timeframe. The 2.0x volume surge trigger keeps trade frequency high enough (~30-60/year) for valid walk-forward optimization — explicitly avoiding the low-frequency channel-breakout pathology that killed the ADA daily multi-week trend strategy.

Implements the hypothesis as a faithful member of the proven FourHourVolumeBreakoutLong family. OP (Optimism) is a currently-listed, liquid Binance USD-M perpetual (OPUSDT.BINANCE), so no symbol substitution is needed — it backtests directly on the reliable 4H data path that avoids the daily-bar audit-refill failures the hypothesis flags. The edge is the family's exact three-condition conjunction: a volume surge (current 4H volume > 2.0x prior-window average) confirmed by a bullish bar and an SMA-100 uptrend filter, capturing breakout continuation on flow events. The 2.0x trigger keeps trade frequency in the ~30-60/year band that the hypothesis requires for valid walk-forward optimization, deliberately avoiding the low-frequency channel-breakout pathology that abandoned the ADA daily multi-week strategy. VENUE: BINANCE USD-M futures; long-only but kept on futures to match the landed family's data path and fee model; leverage=1.0 and explicitly read in sizing (notional = equity*per_leg_pct*leverage) so there is no leverage_set_but_unused gate risk. FEE VIABILITY: 5% TP / -5% SL targets sit far above the ~0.10% round-trip taker cost, so per-trade edge clears fees. calculate_signal returns a continuous, bar-varying volume-surge/body/regime score thresholded at 0.5 in should_enter — not a gated constant — satisfying the verifier. Four tunable parameters (volume_mult, volume_window, sma_trend_period, per_leg_pct) give the optimizer room while locked risk constants fix exit discipline.

Low-liquidity arm of an already-validated family — not worth 2 hours of optimization. The code is a faithful port and trades as specified, but the base economics are below the threshold where optimization helps: Sharpe 0.25, profit_factor 1.04 (fees consume nearly all gross edge), expectancy +$32/trade (~0.16%, right at the fee bar). Two structural, non-tunable blockers seal it: impact_cost_pct 25.1% (market impact eats a quarter of gross PnL) and capacity_usd just $1.58M (edge real only at toy scale) — both are set by OP's order-book depth, not by parameters. The edge is also decaying: profit concentrated in 2022 (+10.6%), then 2024 -9.3% and 2025 -4.2% with rolling Sharpe negative across 2024-2025, so a recent holdout would likely fail. Decisive precedent: the DOT sibling of THIS exact FourHourVolumeBreakoutLong family was fully optimized to Sharpe 1.69 and still abandoned (DSR 0.24, negative holdout); OP starts weaker (base Sharpe 0.25 vs DOT 0.51), so the 2-hour sweep would re-reach the same abandon. Not iterate: no code bug (faithful family port) and no parameter change fixes a 0.25 Sharpe with 25% impact cost, $1.58M capacity, and negative recent years; reducing size lowers impact but worsens the already-thin per-trade edge. The mechanism's value is already captured by the promoted major-asset siblings (BTC/ETH/SOL/BNB/AVAX/XRP); OP is the negative arm of the family's asset-selectivity. FAILURE PATTERN: the FourHourVolumeBreakoutLong family does not generalize to lower-liquidity alts — on OP the base config shows a marginal edge (Sharpe 0.25, PF 1.04, ~0.16%/trade) crippled by impact_cost 25.1% and tiny capacity ($1.58M), the same liquidity-limited failure that abandoned the DOT sibling.

Long-only 4-hour volume-breakout strategy on OPUSDT.BINANCE USD-M futures, a direct port of the landed FourHourVolumeBreakoutLong family (BTC/ETH/SOL/BNB/AVAX/XRP/APT/ICP/ARB) applied to OP (Optimism). Enters long when a 4H bar's volume exceeds volume_mult (2.0x default) the prior volume_window-bar average AND the bar is bullish (close>open) AND price is above its SMA(sma_trend_period) uptrend filter. Exits on +5% take-profit, -5% stop-loss, or a 14-bar (~2.3 day) max hold. Sizes each position at per_leg_pct (20%) of account equity, capital-relative via get_account_equity(), with 1-decimal OP quantity precision (step 0.1).

Faithful port of a validated family; code trades exactly as specified (131 long-only volume-surge entries, clean 3-condition conjunction)

Low fee drag in commission terms (commission_pct_of_gross 2.96%) and positive expectancy in absolute terms

Healthy raw trade count (131) — sparsity is not the problem here

Marginal edge: Sharpe 0.25, profit_factor 1.04, expectancy +$32/trade (~0.16% on a ~$20k position) — barely above trading costs, no margin of safety

Capacity/impact is a structural blocker on a low-liquidity alt: impact_cost_pct 25.1% (impact eats a quarter of gross PnL) and capacity_usd only $1.58M (edge exists only at toy scale) — neither is tunable, both are set by OP order-book depth

Recent decay: profit concentrated in 2022 (+10.6%), then 2024 -9.3% and 2025 -4.2%, with rolling Sharpe negative across 2024-2025

Family precedent: the DOT sibling of this exact strategy was optimized to Sharpe 1.69 and still ABANDONED (DSR 0.24, negative holdout). OP starts weaker (base Sharpe 0.25 vs DOT 0.51) — the lower-liquidity arm of this family does not survive the gates

This strategy ported the proven volume-breakout family — landed across many liquid majors — to OP on 4H bars, entering long on a 2.0x volume surge with a bullish bar in an uptrend. It traded cleanly 131 times but had only a marginal edge (Sharpe 0.25, profit factor 1.04, ~0.16%/trade), and was crippled by structural liquidity limits: impact cost consumed a quarter of gross PnL and capacity was just $1.58M, with profit concentrated in 2022 and negative in 2024-2025. The analyst abandoned it at the backtest-review gate on the first iteration as the lower-liquidity arm of the family — citing the DOT sibling that optimized to 1.69 yet still failed, and noting nothing tunable could fix a 0.25 Sharpe with 25% impact and toy-scale capacity — so it never advanced to optimization or risk review.

The FourHourVolumeBreakoutLong family does not generalize to lower-liquidity alts — on OP a marginal edge (Sharpe 0.25, ~0.16%/trade) is crippled by 25% impact cost and a $1.58M capacity ceiling that no parameter can fix, since they're set by order-book depth; the mechanism's value is already captured by the liquid major-asset siblings.

The backtest-review analyst issued an 'abandon' verdict: the code was a faithful family port but the base economics sit below where optimization helps (Sharpe 0.25, PF 1.04), and two non-tunable structural blockers set by OP's order-book depth — 25.1% impact cost and $1.58M capacity — plus recent decay seal it; the DOT sibling of this exact family was optimized to Sharpe 1.69 and still abandoned, and OP starts weaker.

A long-only OP (Optimism) 4H volume-breakout strategy on Binance USD-M futures — a faithful port of the landed BTC/ETH/SOL/BNB/AVAX/XRP/APT/ICP/ARB FourHourVolumeBreakoutLong family — entering on a 2.0x volume surge with a bullish bar above a 100-bar SMA, exiting on ±5% PnL or a 14-bar (~2.3-day) time stop.

Across 131 trades it returned +5.58% with a marginal edge: Sharpe 0.25, profit factor 1.04, expectancy +$32/trade (~0.16%, right at the fee bar), a 20% max drawdown, with profit concentrated in 2022 (+10.6%) then negative recent years (2024 -9.3%, 2025 -4.2%); decisively, impact cost was 25.1% of gross PnL and capacity only $1.58M.
