Screeners

The fixed, human-vetted equity universe. Deliberately not discovered: repeat observations of the same names make per-symbol stats meaningful, and dip-buying needs pre-vetted quality.

Today's biggest movers from Alpaca's live screener — how you'd source candidates for an opening-range or gap strategy. Filtered to tradable common stock; the raw list is mostly warrants and penny pumps. Live-only, so it can't drive a backtest.

Coins actually going somewhere today, with a liquidity floor so the rank doesn't fill with untradeable microcaps. For breakout strategies, which need movement to break out of.

Coins that pulled back today — fallers only. The mirror of crypto-movers, because ranking on absolute move would hand a dip-buyer names that just ran up.

Stocks worth selling a cash-secured put on, re-tuned 2026-10-01 to the 10-year full-cycle wheel backtest (pnpm backtest:wheel — assigned shares' P&L counted). Gates: affordable (one 100-share contract = price × 100 of collateral, indivisibly — Max share price is the budget knob), above their own MA200, still rising over 6 months, realized volatility in the 25–55% band (≥80% names like MARA/COIN were the backtest's worst: rich premium, assignments that never recover), and liquid in dollar volume. Ranked by 6-month trend strength — the backtest's clearest driver of wheel returns. Has NO earnings gate — Alpaca provides no calendar.

Data

Alpaca daily bars, over the core universe UNIONED with yahoo-screener's quality-vetted names (Tier 1/2 or $50B+). Alpaca is both where we screen and where we trade; the sibling app contributes the name list only, never a price. Alpaca most-actives was rejected — volume-ranked, so it is mostly sub-$10 low-float names nobody should be assigned into. NO earnings calendar (see the module header).

QSR's quality universe (the sibling yahoo-screener's Tier 1/2 and $50B+ names, ~320 tickers) narrowed to the 50 most liquid by 20-day average dollar volume, measured on completed sessions only. A quality list for dip-buyers that isn't a hand-picked set of past winners.

Data

Names from the sibling yahoo-screener app (its QSR-tracked quality list: Tier 1/2 or $50B+ caps; /api/qsr-chart-data, a ~6MB response, fine for a screen resolved a couple of times a day). Liquidity ranking from Alpaca daily bars — Alpaca is where every order goes; yahoo-screener supplies the list only, never a price.
