Every number is computed from this strategy’s own resolved signals — each card’s entry, targets, and stop measured against where price actually went. Win rate counts a Target 1 or Target 2 hit as a win and a stop as a loss; expired signals are excluded from win rate and average return. The equity curve sums each signal’s return at a 10-position book · 10% per trade · illustrative. Past performance does not guarantee future results.
