Proof before capital

Your backtest looks great. Is it real?

DualQuant is an independent check for trading strategies. Describe yours in plain English and get a verdict in under a minute: could every trade really have happened, and did it pay for the risk it took?

A real verdict REJECTED
SPY, 20/50 moving-average cross

It made money, but not enough to justify the risk it took.

Return a year, at the same 19.5% worst drop
The strategy+7.63%
A passive blend of SPY and cash+9.51%
-1.88 percentage points a year, against the blend

The best-known strategy in the world, rejected. A check is only worth something if it can say no.

every run reads market data we source and fingerprint ourselves

Private preview, as of 6 November 2026. We built every check on our own crypto, gold, index and FX strategies first, and every headline number moved down. We are now taking the first submissions from outside.

How to start

From idea to verdict in three steps

1

Ask for a key

Tell us what you are testing. Accounts are issued by hand during the private preview, and we reply with an API key.

Email us ->
2

Send your strategy

Write it the way you would explain it to a colleague, or send structured rules. Use the browser page at api.dualquant.ai/app, or give the key to an AI agent: the API explains itself.

Confirm it, read the verdict

We restate your strategy as rules and you confirm them. If anything is ambiguous, we ask rather than guess. Then the plan is frozen, the checks run, and the report comes back in plain words.

What we do

Two questions, one standard of evidence

Neither mode tells you what to buy, hold or sell. Each one shows you what is there.

MODE 1

Strategy Verification

Is the record real, and was it worth the risk?

Five checks run in order and stop at the first failure. Every trade is rebuilt from raw bars by an auditor that shares no code with the simulator. You get one of four verdicts, the reason in plain words, and what trading costs would take from the return.

The five checks
  1. Data Proof
    Are the bars clean, complete, and the ones the plan named?
  2. Replay Not built
    Does a stored external run reproduce exactly? We have not built this, and every verdict reports it as not run.
  3. Executable Proof
    Could every trade have happened in real time, at a price its own bar actually traded?
  4. Consistent Context
    Does the edge hold across the history, or rest on one lucky stretch?
  5. Value Context
    Did it beat a passive blend at the same worst loss, and how long was it underwater?

Failing a Proof check means the result is invalid. Context checks tell you whether it was worth having.

It says whether the record is real and worth its risk. It does not say what the strategy will do next.

MODE 2

Company Research

What do this company's own filings say?

Ask for a ticker and see the company the way its own SEC filings describe it, ten years at a glance.

Every figure comes from a filing
ten years, charted Revenue, net income, free cash flow and total liabilities, one column per fiscal year.
latest annual report Margins, return on equity, debt and cash, worked out from the filed figures.
quarterly results Revenue, net income and earnings per share as filed, against the same quarter a year earlier.
insider purchases Open-market buys by the company's own officers, with grants and option exercises left out.

Each figure is dated by its filing, which is when the public could first have seen it. There are no prices on the view: it links to a public chart instead.

No score and no valuation model: no discounted cash flow, no cost of capital, no fair price. Stocks only, since a fund has no margins or insiders to read.

Why this setup

Fast, clear, and honest by design

Each of these is a property of how it is built, not a promise.

CLARITY

One answer, in plain words

One of four verdicts, the reason named, the comparison spelled out, every term defined on the page, and a list of what the verdict does not claim.

SPEED

A minute, not a weekend

A pre-flight tells you whether your rules are supported and the data is ready before anything runs, and a refusal there costs nothing. Then the full check, start to finish, in one sitting.

AGENTIC

Built for agents as well as people

The API explains itself, so an agent can read the contract, submit rules and read the result as JSON without being taught. People without one use the same API from a browser page.

TUNING

Tune freely. Every attempt is counted.

The report names what is weak: concentrated profit, exits that decided nothing, costs, long stretches underwater. The changes are yours. The more you try on the same data, the higher the bar, so a pass still means something.

NO BIAS

Our data, your frozen plan

Every verdict rests on the same fingerprinted market data, so any two are comparable. Your plan is locked before the first bar, so the rules cannot drift toward the result.

Seven things we do not do, by construction
  • Never publish a rank. In-sample rankings do not predict out-of-sample winners.
  • Never suggest a parameter. It would be an uncounted step in your search.
  • Never fix a broken strategy. We say where it fails. The design stays yours.
  • Never issue a weak pass. No bar is lowered to avoid disappointing anyone.
  • Never call a backtest a forecast. A verified history says what happened, not what will.
  • Never publish your strategy. It is held against your account and shown to nobody.
  • Never trade against you. The platform is isolated from any broker.
The method, in full
What each check does and why, how the risk-matched comparison is built, how your attempt count changes the bar, and the three things we have not built.

Pricing

One price. Unused attempts roll over.

One attempt is one complete verification of a frozen plan, or one company view, over the API.

Subscription
$20 per month
20 attempts
  • Every report in full: the verdict, the reasons, the costs, and what it does not claim
  • Unused attempts roll over for as long as you stay subscribed
  • Top up anytime: 20 more for $20, and those roll over too
  • Cancel at any time. Attempts you have paid for stay in your account
  • One balance for both: a verification or a company view uses one attempt

What to expect

Most strategies do not clear this bar, and ours did not either. That is what you are paying for: a check rather than a compliment.

Buying more attempts does not lower your bar

Attempts are a balance, not a discount. Paid for or not, every idea you test counts toward the bar.
