PURPOSE-BUILT ANALYSIS

See what the headline profit hides

Inspect the path behind the result: drawdowns, recovery periods, monthly consistency, trade streaks and concentration by symbol or Magic number.

01

Drawdown analysis

Measure peak-to-trough loss, recovery time and the periods that put the most pressure on capital.

02

Trade breakdown

Filter trades by symbol, Magic number and direction, then review streaks and entry timing.

03

Monthly consistency

Compare monthly and yearly returns instead of judging an EA by one final balance figure.

REAL REPORT EXAMPLE

A large return still needs a risk explanation

The public example contains 181 XAUUSD H1 trades from January 2025 through July 2026. A 5,000 USD initial deposit produced 21,192.70 USD in net profit, while reported Balance DD reached 15.95% and Equity DD reached 18.87%. The example is an MT5 report, but the same core trade, balance and monthly analysis is applied to supported MT4 HTML reports.

How to review an MT4 EA backtest

Start with the path of returns rather than the final balance. Check whether profit depends on a small number of outsized trades, how long losing periods last and whether performance appears across different calendar months. Then isolate symbols, Magic numbers and directions to see which part of the report actually produces the result.

  • Compare net profit with peak-to-trough drawdown.
  • Review losing streaks and time below the previous balance high.
  • Inspect monthly consistency and concentration by trading hour.

What the analyzer calculates

Backtest Lens rebuilds the closed-trade timeline, balance curve and underwater drawdown from the report. It groups performance by month, year, symbol, direction and Magic number. Account-history cashflows are separated from trading profit, preventing deposits and withdrawals from being presented as EA performance.

  • Filters recalculate the selected trade subset.
  • Calendar months without trades remain visible.
  • Reported MetaTrader drawdown is kept distinct from reconstructed closed-trade drawdown.
SCOPE AND LIMITS

What this analysis does not prove

  • The input must be an MT4 HTML or HTM Strategy Tester or account-history report.
  • Results inherit the modeling assumptions, spread and data quality of the original backtest.
  • A backtest is research evidence, not a promise of future performance.
