AlfaCat Stocks

Run a multi-filter screener, size positions by risk, Monte-Carlo backtest your portfolio and track P&L on-device. No account, no ads, no tracking. Education, not advice.

AlfaCat is a native toolkit for studying the markets: a multi-filter screener across US stocks, ETFs, crypto, FX, commodities and world indexes; an on-device portfolio with day-over-day P/L; a position sizer and reward-to-risk calculator; and a Monte-Carlo backtest lab. It runs on calm end-of-day data — one snapshot per trading day, cached so your tools keep working offline — so you screen, plan and learn without streaming noise. Everything you create (watchlists, holdings, presets, alerts) is computed and stored on your device. No account, no ads, no tracking.

MARKETS • Headline stats and an index chart for quick context • Today's top gainers and losers at a glance • A freshness banner that always tells you how recent the data is

NEWS • A feed of headlines for the instruments in the universe • Jump from a headline straight to the ticker's chart and key metrics

SCREENER • Search and sort the whole universe: US stocks, ETFs, crypto, FX, commodities and world indexes • Filter by asset class or by cross-cutting themes • Save filter combinations as presets — stored on your device

WATCHLIST AND PORTFOLIO • Pin instruments to a watchlist and see them first on the dashboard • Record your holdings and follow their value and day-over-day change • Everything stays on your device — there is no account and nothing is uploaded

LAB • Position sizer: enter an account size and a risk percent, see the implied position • Reward-to-risk calculator for planned entries, stops and targets • Historical portfolio replay with basic stats — a look back, not a forecast

GLOSSARY • 35 plain-English finance terms, from VWAP to drawdown • Written for learners: short definitions with practical context

AND MORE • Ticker pages with about a year of daily price history and previous-session tiles (open, close, VWAP, high, low, volume) • Compare two instruments side by side • Earnings calendar with upcoming report dates • Optional on-device price alerts

BUILT TO RESPECT YOU • Free, with no ads, no tracking, no account and no sign-up • Works offline on the last data it saw • End-of-day data only — a study tool, not a trading terminal; you cannot place orders here
