Strategy Safety Grade: B (60 / 100) · Moderate Quality
Trading risk analysis result
Strategy Type: Strict Lot Discipline. Classified as Single-Order Trend (lot-size discipline): the backtest shows a 96.94% win rate and 3.16 PF, but the extreme payoff asymmetry (0.10) and six losses averaging -$4,119 create a fragile risk profile where a single catastrophic loss of -$14,622 erased 25% of equity; the strategy's safety score of 60 (Grade B) reflects robust organic profit but elevated drawdown and negative payoff.

- Timeframe: H1 (2025.01.03 - 202

Critical Algorithmic Vulnerabilities
- Payoff Asymmetry Fragility (La): With a 96.94% win rate and a 0.10 payoff ratio, average winners ($410) are dwarfed by average losers ($4,119); a single loss of -$14,622 (Oct 21, 2026) erased 25% of the then-prevailing equity, showing that one adverse event can overwhelm dozens of small wins.
- Outlier-Independence is Weak: Top 5% trades account for 14.04% of gross profit, and although the residual PF remains 2.71, the three largest winners are themselves modest (largest win $1,218.50), indicating the profit stream relies on a high-frequency of tiny gains rather than fat-tail expansion—a structure vulnerable to any sustained rise in slippage or spread.
- Drawdown Depth & Recovery: Maximum drawdown reached 26.64%, exceeding the 20% threshold, and the largest single loss (Oct 21, 2026) alone cut equity by ~20%; without a verified hard stop, a repeat could compound with the next loss streak.
- Concentration in Short Direction (Rs): 77% of trades are short, exposing the strategy to a one-sided regime shift; the 664-day sample shows 96.9% winning shorts but the six losses may indicate asymmetric vulnerability when market direction reverses.
Score Breakdown Details
- [Base Score] All valid statements start at 50 points neutral benchmark (Grade B-)
- +15 pts [Lot Discipline]: Fixed/proportional lot execution, no adverse counter-trend doubling
- -20 pts [Poor Payoff]: Win/loss payoff ratio only 0.10 (< 0.6), losses heavily erode gains
- +5 pts [Expectancy]: Overall Profit Factor reached PF 3.16 with solid positive mathematical expectancy
- +10 pts [Organic Profit]: Removing top 5% windfall deals leaves PF 2.71 >= 1.2; robust and non-luck-driven
- -10 pts [Elevated Drawdown]: Max historical drawdown reached 26.6% (20%-35%), downside pressure elevated
- +10 pts [Sample Horizon]: Sample duration spans 664 days (>= 180 days), covering diverse regimes
- Final Strategy Safety Score: 60 / 100 (Grade B).
Recommended Next Actions
- Obtain paired entry-ticket data to determine whether the same-minute orders are independent signals or a tiered basket, which would refine the strategy classification.
- Run a forward demo test on the target broker to measure live slippage and spread impact, especially on the small average wins ($410) which are highly sensitive to transaction costs.
- Verify the actual execution of the configured stop-loss (EURUSD SL 60, etc.) by inspecting a live trade log; the current six losses do not confirm stop discipline.
- Evaluate the strategy’s sensitivity to a 20–30% increase in spread and commission, as the high win rate relies on thin profit margins per trade.
Q&A About This Report (Quant Due Diligence)
Why does a 96.94% win rate not translate to a high safety score?
The score of 60 (Grade B) reflects the extreme payoff asymmetry: average winners are $410 while average losers are $4,119 (payoff ratio 0.10), meaning a few large losses can erase dozens of small wins. The maximum single loss of -$14,622 on Oct 21, 2026, alone eliminated 25% of the then-current equity, and the 26.64% maximum drawdown is above the 20% threshold. Despite the high win rate, the risk of a single catastrophic loss keeps the strategy at a moderate safety grade.
The backtest shows a 3.16 profit factor and a 2.71 PF after removing the top 5% of trades. Is the strategy overly dependent on outliers?
No, the outlier dependency is limited: the top 5% of trades (10 trades) account for 14.04% of gross profit, and excluding them still leaves a net profit of $42,322 with a 2.71 profit factor. This robustness supports the organic profit assessment in the score. However, the profit stream itself is not outlier-driven but rather relies on a high frequency of small consistent wins, which is inherently sensitive to cost increases.
Does the strategy use a hard stop loss? The trade table shows zero stop-loss parameters and an unbounded tail in loss sizes.
The configured parameters list stop-loss values (e.g., EURUSD SL 60.0), but the parsed trade rows show no stop-loss prices and the six recorded losses vary widely (median -$4,326, max -$14,622, ratio 3.38). The stop-loss evidence pattern is 'unbounded_tail', meaning losses did not terminate at a consistent level. With only six losing trades, the sample is too small to confirm whether a consistent hard stop is executed; verification via live trade logs is required.
The strategy is short 77% of the time and achieved a 96.9% win rate. What risk does this directional bias pose?
A 77% short bias exposes the strategy to a regime shift where EURUSD trends upward. The current backtest period (2025-01 to 2026-11) may have favored short setups, but the six losing trades already include losses from short positions (e.g., -$14,622 on Oct 21, 2026). If the market transitions to a sustained uptrend, the win rate could deteriorate rapidly, triggering the large-loss tail that the current risk controls may not contain.
