Applies the backtest-validated trailing stop to live paper trading, and surfaces it transparently. Exit (A): - New paper-trade exit policy (paper_exit_mode=trailing, paper_trailing_pct=12), tunable in Admin → Paper-Trade Exit. resolve_open_trades runs a trailing stop (initial stop as floor, ratchets up from the peak; target ignored — the validated rule) and records close_reason (trailing|stop|target|manual; +migration 013). - list_trades enriches open trades with the live trailing-stop level + distance %. Open Trades panel shows the active tactic and a Trail Stop column. Alerts (B): - Daily digest now lists open trades with unrealized gain, trailing stop, and how far away it is. - New "trade closed" alert: one summary per auto-close (trailing/target/stop, not manual) — direction, reason, days held, P&L abs+%/R — covering wins AND stop-loss losses. Deduped by trade id; toggle in Admin alerts. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
