No signals yet — this strategy is waiting for its rules to fire on live end-of-day data. That's the ledger being honest.

Forward testing has no survivorship bias — signals are recorded as they happen, on the symbols the strategy actually watches. Historical simulation for research and education. Not financial advice. Past performance does not predict future results.
