Three usability fixes: 1. Global ticker search in the sidebar (TickerSearch) — typeahead over the tracked universe that opens a ticker's detail page without adding it to the watchlist. Also wired into the mobile nav. 2. Watchlist table shows the ticker's 12-1 momentum percentile (the top-pick selector) instead of the noisy full S/R-level list. Enriched from the setup already loaded in watchlist_service._enrich_entry — no extra query. 3. Alpha vs the S&P 500 on paper trades (open + closed). New benchmark_prices table + benchmark_service store SPY daily closes (a standalone series, not a Ticker, so it never enters the scanner / momentum ranking / rankings) via a new daily-pipeline step. paper_trade_service computes per-trade benchmark_return / alpha_pct / alpha_usd over each holding period; the open- trades table, dashboard, and closed-trades panel surface per-trade and total alpha. The list read path never makes a provider call. Deploy: alembic upgrade head, then run the benchmark/daily job once to populate SPY closes (alpha shows "—" until then).
