20-day breakout on 2× volume
A breakout without volume is a trap: price pierces the high, everyone piles in, and the move dies because there was no money behind it. Doubled volume is the confirmation that an institution is on the other side.

What this result does NOT say
- One market, one universe
- Measured on 105 spot cryptocurrency pairs, delisted ones included. It says nothing about futures, equities or indices, nor about how the same technique behaves in another market.
- One window of time, not every window
- The measured period runs from 2017-08-17 to 2026-07-28. A market moves through regimes, and a technique can work in one and fail in another — the card measures the regimes that fit inside this window, not the ones still to come.
- One cost structure
- The cost charged is 0.10% per leg, in and out. Anyone paying more than that gets a worse result, and anyone paying less gets a better one — the verdict holds for this fee.
- One exit rule
- The trade was closed by: the auditor's fixed horizon (10 bars). The same entry measured with a different exit is a different strategy, and can earn a different verdict — it happens in this archive.
- The number of trades is not the sample size
- There are 3,121 trades, but only 266 independent market episodes: a single move fires the technique across dozens of assets at once, and counting those as separate observations inflates any result. It is the smaller number that governs the arithmetic. With 266 episodes, what the data supports is a range from -2.12% to +2.80% per trade — the published average is the centre of it, not the exact measurement.
- Daily bars
- Measured at the daily close. Nothing here measures what happens inside the day, and an intraday technique is not auditable with this data.

Hypothesis, filed before the result
This is the archive's first CONDITIONAL claim: it does not say breakouts work, it says breakouts WITH volume work and without volume do not. The plain breakout has already come out INCONCLUSIVE, dying at the placebo. Specific prediction: the volume filter does not change the verdict, and its main effect will be to cut the n — which WORSENS the error bar instead of improving the signal. If I am wrong, the pair (with filter × without) is the cleanest evidence this archive will ever have that volume informs something.
the filing date is not in this audit's record
The original, as it was filed
Esta é a primeira alegação CONDICIONAL do corpus: não diz que rompimento funciona, diz que rompimento COM volume funciona e sem volume não. O rompimento simples já saiu INCONCLUSIVO, morrendo no placebo. Previsão específica: o filtro de volume não muda o veredito, e o efeito principal dele será cortar o n — o que PIORA a barra de erro em vez de melhorar o sinal. Se eu estiver errado, o par (com filtro × sem filtro) é a evidência mais limpa que o corpus vai ter de que volume informa algo.
Pre-registration exists to keep prediction apart from rationalisation: written after the number, every hypothesis is right.
Earlier audits of the same technique
Each variation an author teaches enters as its own test, so that whatever might work in the strategy gets covered. The verdict held in all of them.
