Bitcoin after a successful Weekly Bullish Retest

Performance after Bitcoin revisits a confirmed breakout level and closes back above it.

HOW TO READ THIS

Context before conviction.

After removing overlapping forward windows, N=4 independent observations remain from 6 raw events. Their 26W median return was +31.72% with a 75% win rate and -14.87% median adverse excursion.

A 4-event independent sample can produce extreme win rates by chance. Treat this result as exploratory.
OVERLAP CONTROL4 of 6 completed 26W observations retained · 33.3% overlapping events excluded from the primary estimate.

OUT-OF-SAMPLE CHECK

Temporal validation

Chronological 70/30 holdouts and expanding-window folds use only independent observations. Later outcomes never influence event selection or thresholds.

At least 8 independent completed observations are required before a chronological holdout is published.

Sensitivity analysis

One detector setting changes at a time around the published configuration. Returns never determine which configuration is canonical.

ASSESSMENT · 26WInsufficient Data

At least 8 independent observations are required for the canonical and compared variants.

This is a robustness check, not model selection. Each row changes one assumption while every other detector rule remains fixed.

VENUE ROBUSTNESS

Cross-exchange benchmark

The published detector is replayed independently on each venue over the shared completed-candle window. Exchange populations are never mixed.

ASSESSMENT · 26WInsufficient Data

Both venues need at least 8 independent outcomes before direction is compared.

Coinbase remains the canonical research source. Bitstamp is an external robustness check; its candles, events, and forward-return population remain separate.

EVENT DEFINITION

Weeks 2–8 · low within +1.5% · close ≥ breakout level

The signal is evaluated only with information available at the event close. Future observations are used solely to calculate outcomes.

STUDY RULES

The source breakout must be a completed weekly close at least 1% above a confirmed pivot high.

A retest may qualify from the second through eighth completed week after breakout.

The weekly low must come within 1.5% above the pivot level or trade through it, then close at or above the level.

A close 1% below the level fails the lifecycle before a later retest can qualify.

Primary confidence and headline statistics use the earliest chronological non-overlapping sample for each horizon; raw events remain reported for audit.

Temporal validation uses the independent sample only: a chronological 70/30 holdout plus expanding-window folds with at least two later observations per fold and no threshold tuning.

Sensitivity analysis changes one detector parameter at a time around the published canonical configuration, compares independent 26W outcomes, requires at least 8 observations per comparable variant, and never selects a parameter from performance.

Cross-exchange robustness replays the canonical detector independently on Coinbase BTC-USD and Bitstamp BTC/USD over their shared completed-daily history. Each source keeps its own signal and non-overlapping outcome population, with at least 8 observations required per benchmark.
