Moving average crossover (20/50) with a stop at the last low and exit on a close below the 200-day average
It caps the loss at the point where the bullish structure breaks down — the last low — and takes the trader out as soon as price loses the long-term average, before the reversal eats the trend's gain.

At its worst the account was worth 10% less than its own best previous moment, and it spent 783 days below that peak.

What this result does NOT say
- One market, one universe
- Measured on 48 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 2018-04-17 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 same technique, measured by another exit
- This technique was also audited under a different exit rule — stop or target, whichever comes first — and there the verdict is <strong>FAILED</strong>. They are different questions about the same technique, and both are published: the claim that passes on a fixed horizon and the claim that passes on the exit the technique itself teaches <strong>are not the same claim</strong>.
- The number of trades is not the sample size
- There are 593 trades, but only 26 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 26 episodes, what the data supports is a range from -2.98% to +5.75% 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.

REPROVADO — 5 parâmetros abertos devem rejeitar.
Pre-registration exists to keep prediction apart from rationalisation: written after the number, every hypothesis is right.
This claim has been audited once — there is no history to compare against.
