Alert backtest: what price did after each fire

Take a price or indicator recipe — "RSI crosses below 35", "price crosses up its 20-day average" — and AtlasVector replays it bar by bar over history. A "fire" is counted once, when the condition flips from false to true — the same way a live alert pings you once, not on every bar the condition stays true. The forward move is then measured over the next 1 / 5 / 21 bars: hit rate, average forward move, and how often the fire reverses (the false-signal rate). Nothing that happened after a fire is used to decide the fire. The replay runs on real price history only.
