Adaptive RSI (14, direct constant)
Varying the calculation period need not be confined to a trend formula: any momentum indicator that moves within a known range can be turned into a smoothing constant, and then governs the line's speed. A high reading means more trend and allows a fast line; a low reading means more noise and demands a slow one. The same indicator once used to measure exhaustion becomes a thermometer for speed.

What this result does NOT say
- One market, one universe
- Measured on 2 spot currency pairs. 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 2020-01-01 to 2026-06-26. 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 a 1.0 pip spread, crossed once. 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 1,241 trades, but only 322 independent market episodes: trades that overlap in time are not independent observations, and counting them as if they were inflates any result. It is the smaller number that governs the arithmetic. With 322 episodes, what the data supports is a range from -0.07% to +0.07% 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
Third declaration, and it corrects an OVERSTATEMENT OF MINE in the second. That one said the source's sensitivity claim 'checks out' and 'is the first claim in the chapter to pass clean'. Measuring over the whole universe instead of 6 assets: HALF holds and half does not. Adaptive RSI 34.97% of sideways bars, 10-period average 19.76%, KAMA 18.90% (540 assets, 244,295 sideways bars). The first part — the adaptive RSI is the most sensitive — is large and robust, nearly double the other two. The second — the 10-period average being more sensitive than the KAMA — is a 0.86-point difference and IT REVERSES ON 42% OF THE ASSETS (the average wins on 312 of 540). That is noise with a slight tilt, not confirmation. What stands verified from the source is that the adaptive RSI is the most sensitive of the three, and that is exactly what it uses to justify the squaring remedy. The two points of the second declaration still stand: the adaptive RSI is a trend line and not an overbought/oversold strategy, and it is not a confrontation with the `RSI oversold/overbought` card. The turnover prediction stands: being the most sensitive, it will have the family's highest turnover. Family prediction, filed before measuring: (1) none of the adaptive averages survives the family's Benjamini-Hochberg in crypto; (2) the control that kills the most will be COST, not the benchmark — unlike the chart-pattern census, where the benchmark was the gravedigger, because these are always-in-the-market systems and they turn over a lot; (3) each adaptive average will have HIGHER turnover than its fixed-period counterpart already in the archive, and will die more at cost than it does. The mechanism is in the source itself: Table 17.1 reports a profit factor 'even before costs' and states that success is 'inversely related to the average number of trades' (KAMA 159 trades, factor 1.53; VIDYA 443, factor 1.17). That is a cost story told as a quality story. If I am wrong and one survives cost with higher turnover, the chapter's thesis gains evidence it did not present. MEASURED IN FOREX (EUR/USD and GBP/USD, daily bars built from 15m), not in crypto. This is a pre-registered REPLICATION of the same technique in the second market — not a new discovery — and the multiple-testing count treats it as such. What changes relative to the crypto card: 2 pairs over 6.5 years against 540 over 9, a round trip costs about 20× less (a 1 pip spread crossed once, against 0.1% commission per leg), the detection floor is about 10× lower (0.092% against 0.97%) and there is NO survivorship bias, because a currency pair does not get delisted. Specific prediction: with only 2 assets, the independent episodes come from TIME and not from the variety of assets, so I expect a low effective N and a high proportion of INCONCLUSIVE — and whatever is asserted here is worth more than in crypto, because cost cannot be the gravedigger.
filed on 2026-07-31, before the number existed
The original, as it was filed
Terceira declaração, e corrige um EXCESSO MEU na segunda. Ela dizia que a afirmação de sensibilidade da fonte 'confere' e 'é a primeira afirmação do capítulo que passa limpo'. Medindo no universo inteiro em vez de 6 ativos: METADE se sustenta e metade não. RSI adaptativo 34,97% das velas laterais, média de 10 períodos 19,76%, KAMA 18,90% (540 ativos, 244.295 velas laterais). A primeira parte — o RSI adaptativo é o mais sensível — é grande e robusta, quase o dobro dos outros dois. A segunda — média de 10 mais sensível que a KAMA — é 0,86 ponto de diferença e SE INVERTE EM 42% DOS ATIVOS (a média ganha em 312 de 540). Isso é ruído com leve inclinação, não confirmação. O que fica verificado da fonte é que o RSI adaptativo é o mais sensível dos três, e é exatamente isso que ela usa para justificar o remédio do quadrado. Os dois pontos da segunda declaração seguem valendo: o RSI adaptativo é linha de tendência e não estratégia de sobrecompra/sobrevenda, e não é confronto com o card `RSI sobrevendido/sobrecomprado`. Previsão de giro mantida: sendo o mais sensível, será o de maior giro da família. Previsão da família, registrada antes de medir: (1) nenhuma das adaptativas sobrevive ao Benjamini-Hochberg da família em cripto; (2) o controle que mais mata será o CUSTO, e não o benchmark — diferente do censo de padrões gráficos, onde o benchmark foi o coveiro, porque estas são sistemas sempre-no-mercado e giram muito; (3) cada adaptativa terá giro MAIOR que a sua contraparte de período fixo já no corpus, e morrerá mais no custo do que ela. O mecanismo está na própria fonte: a Tabela 17.1 relata fator de lucro 'even before costs' e afirma que o sucesso é 'inversely related to the average number of trades' (KAMA 159 operações, fator 1,53; VIDYA 443, fator 1,17). Isso é uma história de custo contada como história de qualidade. Se eu estiver errado e alguma sobreviver ao custo com giro maior, a tese do capítulo ganha uma evidência que ele não apresentou. ⚠️ MEDIDO EM FOREX (EUR/USD e GBP/USD, diário agregado de 15m), e não em cripto. Isto é uma REPLICAÇÃO pré-registrada da mesma técnica no segundo mercado — não uma descoberta nova —, e a conta de múltiplos testes a trata como tal. O que muda em relação ao card de cripto: são 2 pares em 6,5 anos contra 540 em 9, o custo do giro é ~20× menor (spread de 1 pip cruzado uma vez, contra comissão de 0,1% por lado), o piso de detecção é ~10× menor (0,092% contra 0,97%) e NÃO há viés de sobrevivência, porque par de moeda não é deslistado. Previsão específica: com apenas 2 ativos, os episódios independentes vêm do TEMPO e não da variedade de ativos, então espero N efetivo baixo e uma proporção alta de INCONCLUSIVO — e o que for afirmado aqui vale mais que em cripto, porque o custo não tem como ser o coveiro.
Pre-registration exists to keep prediction apart from rationalisation: written after the number, every hypothesis is right.
