Moving average crossover (20/50) · exit by 3 × average true range of 10
A trend technique delivers its result despite the trades that turn against it, not because of them. Cutting each trade as soon as price moves far enough from its own best point takes the loss before the technique itself notices the turn — and what remains is better than having no stop at all, provided the level adapts to volatility instead of being a fixed amount.

At its worst the account was worth 45% less than its own best previous moment, and it spent 566 days below that peak.
What was measured
How many of those trades actually count
What it paid, before any deductions
Why it passed
- the profit spread across the trades instead of coming from a handful
- the edge survived the broker's fee
- it paid more than entering on randomly drawn dates
- it paid more than buying and holding for the same stretch
- the result came back in the separated pieces of the data
- it survived the discount for having tested many versions
What would have happened to the money
The account would not fit every signal
The effect sits at the start of the period, not the end
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 14,842 trades, but only 256 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 256 episodes, what the data supports is a range from +0.95% to +5.42% 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
Adjusting the stop by volatility, at three times the current 10-day average true range, measured from the trade's favourable extreme. It backs away on 40.3% of the bars and on 100% of the trades — it enters as an exit rule, for the same reason as the dev-stop. Family-level prediction, recorded before measuring: (1) the stop IMPROVES concentration and worsens the mean — it cuts the right tail along with the left, and control 1 is where the 20/50 crossover already dies; if any card in this family changes its verdict relative to the base, I expect it to be by clearing the invariant, not by gaining return; (2) the VOLATILITY stops will do better than the fixed percentage, because that is what the source claims («the ones most likely to work need to adapt to volatility, and not to a fixed value in money or percentage of price») and the claim is testable; (3) the 12 × average true range of 252 will almost never be touched — it is far too wide a stop for crypto, and will measure practically the same thing as the base with no stop; (4) the profit TARGETS will do worse than the stops, because the source's own table shows that the best result for the slow average was WITHOUT profit taking; (5) none survives the family's Benjamini-Hochberg.

The original, as it was filed
Ajustar o stop pela volatilidade, a três vezes a amplitude real média corrente de 10 dias, medida do extremo favorável da operação. ⚠️ Recua em 40,3% das velas e em 100% das operações — entra como regra de saída, pelo mesmo motivo do dev-stop. Previsão da família, registrada antes de medir: (1) o stop MELHORA a concentração e piora a média — ele corta a cauda direita junto com a esquerda, e o controle 1 é onde o cruzamento 20/50 já morre; se algum card desta família mudar de veredito em relação à base, espero que seja por sair do invariante, não por ganhar retorno; (2) os stops de VOLATILIDADE irão melhor que o percentual fixo, porque é isso que a fonte afirma («os que têm mais chance de funcionar precisam se adaptar à volatilidade, e não a um valor fixo em dinheiro ou percentual do preço») e a afirmação é testável; (3) o 12 × amplitude real de 252 dias quase nunca será tocado — é um stop largo demais para cripto, e vai medir praticamente a mesma coisa que a base sem stop; (4) os ALVOS de lucro irão pior que os stops, porque a própria fonte mostra na tabela dela que o melhor resultado da média lenta foi SEM tomada de lucro; (5) nenhuma sobrevive ao Benjamini-Hochberg da família.
Quotations from the source were translated from the Portuguese record and back into English — they are not the author's exact words.
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 changed along the way — a fix in the engine changes the number, and that is a fact that has to stay visible. No earlier record was deleted.
