40-day average by the direction of the line · exit by 10σ volatility with re-entry at ¼
A one-day move far larger than normal is risk, not opportunity: exiting on it cuts exposure to the worst of a price shock without waiting for it to become a loss in the account. And because trend systems live off the few very good trades, going back in as soon as the agitation passes recovers the tail the exit would have cost.

What this result does NOT say
- One market, one universe
- Measured on 540 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 technique itself (held until the opposite signal). 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 49,643 trades, but only 29 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 29 episodes, what the data supports is a range from -1.22% to +5.45% 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.

Equity — outside the six controls, and here is why
The t of the trade series is invariant to bet size: 0.5%, 1% and 3% agree to the sixth decimal. Nothing here moves the verdict — it moves what the account would have lived through.

Hypothesis, filed before the result
The same exit, replacing rule 4 with the reset rule on p. 866: «we will be able to re-enter the market in the same direction as the trade that just exited, but only when volatility falls to ONE QUARTER of the volatility (the daily return) on the day of the exit. The concept is that, at one quarter of the volatility, the market is more or less back to normal». IT IS THE LARGEST IMPROVEMENT CLAIMED IN THE WHOLE CHAPTER, and by a margin nothing else comes close to — Table 20.3, 30-year bonds: net profit of 4,500 with no volatility exit, 12,968 with the exit, and 34,781 with the exit and re-entry, with the profit factor going from 1.02 to 1.07 and to 1.16. It is also the only layer in this family that GIVES exposure back instead of taking it away, and the source's justification is this corpus's own protocol: «trend systems need to capture as much as possible of the very good moves». Family-level prediction, recorded before measuring: (1) NONE survives the corpus-wide Benjamini-Hochberg — a filter that only decides WHEN NOT TO ENTER does not create an effect, it redistributes one; (2) the gravedigger will be the BENCHMARK, and not the placebo, and this is where this family parts from `fibonacci`: there the claim was that one specific level matters, and the placebo is what asks that; here the claim is that REMOVING TRADES IMPROVES THE RESULT, and what asks that is the control that compares against doing nothing — the protocol already records that a filter almost always cuts `n` without separating anything; (3) the LOW volatility filter and the HIGH one will give results IN THE SAME DIRECTION, despite the source claiming the low one is superior with two numbers and no error bar (information ratio 1.143 against 0.867) — if both improve, what improves is cutting trades, not picking a regime; (4) the RESET rule will have the family's best `t`, being the only layer that gives exposure back instead of taking it away, and even so it will not pass the BH; (5) the BASE will do better than any layer built on top of it.

The original, as it was filed
A mesma saída, trocando a regra 4 pela regra de reset da p. 866: «vamos poder reentrar no mercado na mesma direção da operação que acabou de sair, mas apenas quando a volatilidade cair a UM QUARTO da volatilidade (o retorno diário) no dia da saída. O conceito é que, a um quarto da volatilidade, o mercado está mais ou menos de volta ao normal». ⚠️ É A MAIOR MELHORA ALEGADA DO CAPÍTULO INTEIRO, e por uma margem que nenhuma outra chega perto — Tabela 20.3, títulos de 30 anos: lucro líquido de 4.500 sem saída por volatilidade, 12.968 com a saída, e 34.781 com saída e reentrada, com o fator de lucro indo de 1,02 a 1,07 e a 1,16. ⚠️ É também a única camada desta família que DEVOLVE exposição em vez de tirar, e a justificativa da fonte é a do protocolo deste corpus: «sistemas de tendência precisam capturar o máximo possível dos movimentos muito bons». Previsão da família, registrada antes de medir: (1) NENHUMA sobrevive ao Benjamini-Hochberg do corpus — um filtro que só decide QUANDO NÃO ENTRAR não cria efeito, redistribui; (2) o coveiro será o BENCHMARK, e não o placebo, e é aqui que esta família se separa de `fibonacci`: lá a alegação era que um nível específico importa, e o placebo é quem pergunta isso; aqui a alegação é que REMOVER OPERAÇÕES MELHORA O RESULTADO, e quem pergunta isso é o controle que compara com não fazer nada — o protocolo já registra que filtro quase sempre corta `n` sem separar nada; (3) o filtro de volatilidade BAIXA e o de ALTA darão resultados NA MESMA DIREÇÃO, apesar de a fonte alegar superioridade do baixo com dois números e nenhuma barra de erro (razão de informação 1,143 contra 0,867) — se os dois melhoram, o que melhora é cortar operação, não escolher regime; (4) a regra de RESET terá o melhor `t` da família, por ser a única camada que devolve exposição em vez de tirar, e ainda assim não passará no BH; (5) a BASE irá melhor que qualquer camada sobre ela.

Pre-registration exists to keep prediction apart from rationalisation: written after the number, every hypothesis is right.
