Report analysis: Sky City EA · MT5 XAUUSD H1 Backtest

Strategy Type: Martingale. Classified as Martingale: The Sky City EA uses a 1.25x lot multiplier with 50-pip step on XAUUSD, generating 51.11% of gross profit from the top 5% of trades while a 41.62% maximum equity drawdown and a residual PF of 1.01 after removing those outliers reveal that live-market fitness is marginal and structurally fragile.

Return = net profit ÷ initial capital × 100%; PF = gross profit ÷ absolute gross loss; expectancy = net profit ÷ number of closed trades; payoff ratio = average win ÷ absolute average loss. Max drawdown uses the value reported by the source report. If the report contains deposits or withdrawals, the return should be interpreted together with the cash flow.

✦ Key risk flags

  • Return Consistency Defect / R+ Outlier & Fat-Tail Dependency: The top 5% of trades (6,256 rows) account for 51.11% of gross profit; removing them leaves residual net profit of only 7,118.77 (PF 1.01), demonstrating that strategy expectancy is materially dependent on statistical outliers rather than a durable systematic edge.
  • Risk Stability Breakdown / Rs Loss Escalation & Stop-Loss Drift: The largest single loss of -1,412.40 exceeds the average loss of -18.41 by a factor of 76.7, and the martingale multiplier (Hand_AddLotMult=1.25) causes lot expansion under adverse price movement; if a trend accelerates against the basket, loss compounding can rapidly exhaust capital.
  • Momentum Decay / D-Score Quote Shape Broken: The maximum equity drawdown of 41.62% from a 10,000 capital base indicates a severe peak-to-trough decline; recovery to new highs may require disproportionately large trend expansions, and the strategy can stagnate underwater for extended periods if trend regimes abort.
  • Payoff Asymmetry Fragility / La Loss Aversion: A payoff ratio of 1.17 and win rate of 63.71% place the strategy in a moderate-payoff regime; if the win rate degrades or average loss expands (as documented by the -1,412.40 largest loss), arithmetic expectancy can flip negative rapidly.
  • Execution Feasibility / Capacity & Friction: The backtest reflects 99% history quality but does not supply live slippage, spread widening, or commission assumptions; the 1.25x lot multiplier on XAUUSD (a volatile instrument) amplifies exposure to real-world execution friction, and the strategy’s reliance on many small trades increases sensitivity to spread and latency.

✦ What the data cannot tell

  • Real slippage, spread, and commission behaviour on the live broker cannot be determined from the parsed evidence
  • Paired entry tickets are not supplied, so the precise basket structure, same-second multi-order coordination, and ticket-level linkage cannot be verified
  • The absence of any demo or real account statement means live execution quality and forward performance remain unobserved
  • The exact stop-loss configuration (hard SL vs. trailing stop) for the martingale basket cannot be confirmed from close-only rows

✦ Next actions

  • Obtain paired entry/exit ticket data from the original MT5 report to verify same-second basket composition and stop-loss placement
  • Reproduce the backtest with realistic spread and slippage settings matched to the intended broker's XAUUSD conditions
  • Run a forward demo test with identical settings to observe live execution friction and drawdown behaviour
  • Stress-test the 1.25x lot multiplier under a 2x historical adverse XAUUSD move to quantify maximum capital impairment
  • Conduct a cost-sensitivity analysis using any available commission or swap data from the broker

Frequently asked questions

The A+ to E safety grade (and 0–100 score) is an AI risk judgement based on the submitted evidence, not a win-rate forecast. Read it alongside the score rationale and blind spots.

Q. Why does the strategy receive Grade E despite a profit factor of 2.06 and a 63.71% win rate?

A. The Grade E reflects internal downside risk metrics, not test quality. The strategy uses a martingale lot multiplier (1.25x) that expands position size under adverse price movement, and the maximum equity drawdown reached 41.62% of the 10,000 capital base. The largest single loss of -1,412.40 is 76.7 times the average loss of -18.41, indicating asymmetric downside exposure. These factors collectively produce a low safety score independent of the positive full-sample profit factor.

Q. The top 5% of trades generate 51.11% of gross profit, yet a residual PF of 1.01 remains after removing them. How should an allocator interpret this?

A. The residual PF of 1.01 indicates that the strategy is roughly breakeven without its largest winners, preserving capital but not generating meaningful net profit. This demonstrates that the strategy’s edge is heavily dependent on a small subset of outlier trades, which is a structural fragility. Allocators should treat the positive full-sample PF as contingent on those outliers continuing to occur in live markets.

Q. What does the 99% history quality mean, and does it mitigate the 41.62% drawdown?

A. The 99% history quality indicates a high-fidelity backtest modelling of historical ticks, which reduces modelling error but does not mitigate the realized drawdown. The 41.62% maximum equity drawdown is a verified outcome within that backtest, calculated from the 10,000 capital base. It represents actual peak-to-trough balance erosion in the tested period and is not offset by the modelling quality.

Q. The evidence flags mention a 1.25x lot multiplier and 50-pip step. How does this affect live execution?

A. The 1.25x multiplier means lot size increases by 25% with each additional entry within an adverse sequence, and the 50-pip step spacing defines the interval at which those entries are added. On XAUUSD, a volatile instrument, this can rapidly amplify exposure if price moves against the basket. The backtest does not supply live slippage or spread data, so the live transmissibility of these settings remains unverified and represents a material execution risk.

Q. How is RBOT different from asking a general-purpose AI assistant (such as ChatGPT, Gemini or Claude) to analyse my report myself?

A. RBOT parses MT4/MT5 reports into structured metrics and trade records before AI review. Supported calculations can be checked against the original export; AI wording and scores can vary and are not guaranteed to be deterministic or comparable across reports. General AI assistants may also use calculation tools. Missing actual slippage, ownership or forward validation still requires other evidence.

Q. Which broker is recommended for trading and running MT4/MT5 strategies?

A. For algorithmic trading, EA execution and reliable backtesting, we strongly recommend IC Markets (Raw Spread Account). Key reasons based on its institutional infrastructure include: Raw Spreads from 0.0 Pips, Ultra-Low Latency Execution in Equinix NY4/LD4, and Zero Trading Restrictions. You can open an account via the IC Markets Official Portal.

Q. Do I need a VPS to run trading EAs and automated strategies?

A. For automated trading EAs running 24/5 uninterrupted, deploying on a high-speed Windows VPS is strongly recommended to eliminate trade disruptions from home internet drops or power outages. We recommend HHOST Cloud Servers (Tier 3+ Data Centers in Hong Kong, Japan, and Singapore, Standard $10/mo plan with Windows, 2 vCPU, 4 GB RAM, 40 GB SSD).
