Most strategies
do not work.

BRIDGE AI turns a trading idea into a precisely specified strategy, backtests it on recorded real market data against a gate whose thresholds were written down before the test ran, and files one verdict — pass or fail — in an archive it can never quietly edit. It does not trade.

How it works

A rejection machine.

Most of what enters the funnel has to die in it. If nothing were dying, the gate would be broken — so failure is the ordinary outcome here, and it is recorded as carefully as a success.

R1 — R4

The bar is set first

Sample floor, expectancy after real costs, profit factor, and a margin over a 20-seed coin-flip control — all fixed before anything is run. A gate you may adjust once you have seen the answer is not a gate; it is a way of writing down what you already wanted to believe.

R4

Beat a coin flip, or fail

The control takes the same entries on the same bars with the same stops and targets, and picks its side at random. Most “edges” are geometry: a wide stop and a tight target win often, and so does a coin flip with the same shape. Beating that control is the only evidence the entries knew something.

R5 — R8

Every result is kept

Pass or fail, each verdict is written to a permanent archive with the exact rules it was judged by and how many strategies had been tested before it. Failures do not quietly disappear, and “we already tried that” stops being a memory.

There is no live path here. A strategy that survives the funnel is evidence, not a promotion. There is no broker, no order placement, no position and no P&L — and no code path from a pass to a trade, because there is no trade.

The vocabulary

Six words. No seventh.

Every strategy leaves with exactly one of these, and the word is fixed in advance. A small, countable vocabulary is what makes “how many have we tested, and how many passed?” an answerable question rather than a story.

pass fail — no edge fail — fragile insufficient evidence unspecifiable disqualified

“Insufficient evidence” is deliberately not a failure — we did not learn anything and we learned this does not work are different facts. “Disqualified” means the test itself was invalid, so its numbers are never shown at all. And a pass is still only a proposal: nothing is shortlisted until a person signs off.
