A 99% win-rate backtest is usually a beautiful lie. TestMyLogic is a desktop app that stress-tests your strategy's backtest for overfitting — before your money finds out the hard way.

Verdicts from statistics. Analysis with your AI agent.

PBO VerdictVERY FRAGILE

BACKTEST — LOOKS UNBEATABLE

WIN RATE

99.3%

TOTAL PROFIT

+40.0%

SHARPE / SORTINO

5.51 / 1.28

MAX DRAWDOWN

3.4%

271 wins, 2 losses — and validation says the edge is an illusion of the parameter sweep. That gap is why TestMyLogic exists.

Your backtest, interrogated

Runs on your machine, on historical data. The app's only network traffic is downloading public market history — no exchange accounts, no telemetry, just statistics doing their job.

PBOProbability of Backtest Overfitting

Combinatorial cross-validation (CSCV) over your entire parameter sweep estimates the odds that your best-looking combo is a fluke — one number that tells you how much to trust the headline result.

WFAWalk-Forward Analysis

Re-optimizes on rolling in-sample windows and measures what survives out-of-sample, fold by fold — the difference between a curve you fit and an edge that persists.

TRADESTrade Diagnostics

Trade-level anatomy: drawdown structure, holding-time distributions, benchmark comparison against buy & hold — the details a summary card hides.

Analysis with your AI agent

TestMyLogic ships with an MCP (Model Context Protocol) surface. Connect the AI assistant already on your machine — it reads the validation verdicts, queries your results with SQL, drafts strategy configs, and drives the app's screens while you watch.

Your bulk data never leaves your machine — the assistant sees only the verdicts, summaries, and configs it works with, through your own AI provider. The agent explains; the statistics decide.

You — "Is my best combo overfit, or real?"

Agent — "PBO is 87% — very fragile. The top combo's edge disappears out-of-sample. Want me to open the walk-forward view and show which folds fail?"

What TestMyLogic is not

We built a measuring instrument, not a money machine. To be explicit:

No trading signals — it never tells you what or when to buy or sell.
No investment advice — outputs are statistical diagnostics of your own backtests.
No exchange connectivity — no account linking, no API keys, no order execution.
No custody — no wallets, no funds, nothing of value passes through it.
Historical data only — public market history, downloaded for local analysis.
