Independent Validation · Algorithmic & Systematic Strategies
We try to kill your strategy before the market does.
An independent testing house for algorithmic and systematic trading strategies. We run your strategy through the battery most backtests never survive — and give you a straight verdict before it touches real capital.

The Problem
Why backtests lie
An equity curve going up and to the right feels like proof. Usually it's one of these three things instead.
Overfitting
Test enough variants and one will look brilliant by pure luck. AI makes it worse — a thousand strategies a day, each fit to the past, blind to the future.
Frictionless fills
Backtests fill instantly at the price you asked for. Live orders don't. Fees, slippage and latency quietly eat edges that looked enormous on paper.
Regime luck
A strategy tuned on one regime often dies in the next. The market that made your curve is not the market you'll trade in.
None of this means your strategy is bad. It means an equity curve is a claim — and claims get tested.
The Audit
The test battery
Every strategy runs the full battery — no skipped tests, no cherry-picked windows — and either way, you'll know exactly why. Futures, equities, FX, crypto, systematic prediction-market models: if it's rules-based and the data exists, it takes the same six exams.
The Deliverable
One of three verdicts
You get a full written report and a 45-minute walkthrough call either way. The verdict is just the headline.
Validated
The edge survived the battery. You get the evidence, its limits, and the conditions under which it holds.
Marginal
Something real is there, but it's fragile. You get exactly what breaks it — and what to fix before it ever sees money.
Rejected
The edge doesn't survive contact with reality. It stings for a day, and it's still the cheapest loss you'll ever take.
We have no incentive to flatter your strategy. The audit is a flat fee — we get paid for the truth, not the outcome.

Who Runs This
Built by a builder
Joshua Berkowitz — Founder, Thinridge
The name is the job description. A funded strategy is a thin ridge — a narrow crossing with real money falling away on both sides, and what gets you over is knowing exactly what's under your feet. A lifetime around markets taught me that most of what looks like footing isn't: it's luck, leverage, and a backtest that flatters you. The Thinridge Protocol exists to find the part that holds — a fixed six-examination battery with weighted scoring and auto-fail gates, applied the same way every time, to every strategy, including the ones I build myself. Most systems don't survive it. That's the point. The few that do have the only thing worth having: one true, tested point of edge in the pile — enough to put your weight on, and to cross without fear. Thinridge holds no positions, trades no client strategies, and sells no signals. Every engagement ends the same way: a Thinridge Score, a registered certificate you can verify, and a straight answer.
