Is your trading edge real,
or just overfit?
An optimizer always finds something. Plateau tells you whether that something is a durable edge or a curve‑fit mirage — across eight independent checks — then lets you build any chart or metric your data allows. All in your browser. Nothing ever leaves your machine.
The same backtest. Two very different futures.
A great in‑sample curve proves nothing. Toggle below to watch an overfit strategy that collapses out‑of‑sample — and the robustness score that would have warned you.
A second opinion your backtest can't give you
Eight robustness checks, a forensic toolkit, and a studio to interrogate your data however you want — the statistics institutions use, for the strategies retail actually trades.
Robustness score
One 0–100 verdict from eight independent overfitting checks — stability, walk‑forward, Monte Carlo, deflated Sharpe and more — each reweighted to what your data supports.
Plateau Intelligence
Build any chart or metric from your data — ask in plain English or compose it. Combine any series with any operator, transform, group and overlay. Runs locally.
Plateau surface
See whether your optimum sits on a broad, safe plateau or a fragile, lonely spike that won't survive contact with a live market.
Walk‑forward
Out‑of‑sample efficiency, rolling folds and edge‑decay — the honest test of whether an edge actually holds up going forward.
Monte‑Carlo risk
Thousands of resampled paths map your real drawdown odds, tail risk (VaR / CVaR / EVT) and Kelly‑optimal position sizing.
Significance
PBO, deflated & haircut Sharpe, permutation tests and an interpretable overfit classifier — your edge measured against pure luck.
Your data never leaves your machine
Plateau runs entirely in your browser. Your reports, trades and parameters are parsed and analysed locally — nothing is uploaded to a server, ever. The edge you're protecting stays yours.
From backtest to verdict in three steps
A tiny include captures each MetaTrader 5 run to a JSON file. You drop it onto Plateau and read the full robustness breakdown.
Instrument your EA
Add the drop‑in PlateauReport.mqh include — no dependencies, just clean JSON out.
Run it in MT5
A single backtest, or an optimization with a forward period for the complete robustness score.
Upload & score
Drag the file onto Plateau and read the 0–100 verdict, the full breakdown, and build your own charts.
