The Validation Toolkit
How to know if a strategy is real before money is on the line. The honest-testing discipline most courses skip — in-sample/out-of-sample, walk-forward, the random-entry control — plus two live calculators you run on your own numbers.
- In-sample / out-of-sample, walk-forward & the random-entry control, taught plainly
- Live sample-size checker & overfitting-risk score — enter your numbers, get a verdict
- The data-quality module: vendor sourcing, contract adjustment, timezone traps
- Report template & pre-flight checklist for every strategy you test
DAY
The discipline between
a pretty backtest and a real edge.
The Core Discipline
Split honestly, walk it forward, beat random entries, and correct for testing twenty variants — the four moves that separate signal from luck.
What Breaks a Backtest
Overfitting red flags and honest cost modeling — the two chapters that explain why most home-built systems die on contact with live markets.
Two Live Calculators
The sample-size checker and the overfitting-risk score — type your own numbers and get a plain-English verdict, right in the toolkit.
Data Quality, Honestly
Where clean data actually comes from, continuous-contract adjustment, and the timezone traps that silently poison backtests.
Report & Checklist
A validation report template and a pre-flight checklist — so every strategy you test gets the same honest interrogation.
Two Editions
The interactive HTML toolkit plus a clean PDF reading edition — both in one download, yours forever.
Real tools you run
on your own numbers.

The honest split, drawn
In-sample / out-of-sample — the one commitment that makes every later test mean something.

Enough trades to trust?
The sample-size checker turns "is 40 trades enough?" into an actual confidence band with a verdict.

Before a dollar is risked
The final gate — every strategy answers the same questions before it graduates from backtest to paper.

Everything you might be wondering.
No — this stands alone. But they pair naturally: the Starter Kit teaches you to build your first algorithm, and this toolkit is the deep version of its testing chapters. If you already have backtests you're unsure about, start here.
No. Every concept is taught in plain English with drawn diagrams, and the two calculators do the actual arithmetic for you. If you can read a win rate, you can use everything in here.
One download with both editions: the interactive HTML toolkit (the two calculators work offline, no account) and a clean PDF reading edition. Plus free updates for life.
No. This is education about testing methodology — no signals, no advice. Trading involves substantial risk of loss; this toolkit exists precisely so you find out a strategy is weak before that risk is real.
