Investing.
A trading cockpit for your own Alpaca account — journal it, automate it, watch it live.
Numyl Investing is a trading cockpit that sits on top of your own Alpaca brokerage account. It does the bookkeeping a serious options-and-stock trader needs but no broker gives you: a true cost-basis ledger for the wheel, directional plays, and share trades, all marked live with real greeks — plus automated strategies that run with guardrails so a bad day can't run away.
Journal what you do by hand, automate what you'd rather not, backtest before you commit, and watch every position on a single desk with live P&L. It runs against paper or live accounts and is live today at investing.numyl.com.
Connect, journal, automate, watch.
Connect Alpaca
Bring your own Alpaca brokerage account — paper or live. Your keys are encrypted and stay yours; Numyl Investing reads positions and places the orders you tell it to, nothing more.
Journal your trades
Run the wheel, buy calls and puts, or trade shares — each in its own journal with a true cost-basis ledger, partial fills, and live marks. The record matches the broker, not your memory.
Automate with guardrails
Hand the repetitive parts to automated strategies — regime options, scalps, mean-reversion — each with daily loss limits, an end-of-day flatten, and a one-click kill switch.
Watch the desk
The Trading Desk shows every strategy and symbol at a glance — status, position, and live P&L. Backtest before you commit, and review realized profit by week, strategy, and symbol.
Every desk, on one screen.
The journals, strategies, and reports a trader cobbles together across spreadsheets and tabs — in one place, marked live.
The Wheel
Sell cash-secured puts and covered calls with an in-house Black-Scholes greeks engine, a true cost-basis ledger, and a weekly P&L report.
Plays
Buy calls and puts — directional options, journaled and marked live, with sell-to-close and partial exits.
Stocks
Buy and sell shares as a manual trading journal: per-lot, partial sells, fees, and live marks.
Trading Desk
Every strategy × symbol on one board — status, open position, and live P&L, refreshed as the market moves.
Automated strategies
Regime options, intraday scalps, mean-reversion and more — each running against your account with daily governors and a kill switch.
Backtesting
Replay a strategy over historical bars with synthetic option premiums to see how it would have behaved before risking a dollar.
Live greeks & quotes
Real-time option quotes (OPRA) and greeks — computed in-house when the broker doesn't supply them — so marks and theta are always there.
Portfolio & P&L
A unified view across wheels, plays, and shares, with profitability reports bucketed by realized date, strategy, and symbol.
Active traders who run the wheel, trade directional options, or scalp shares and want their book to match their broker — with the option to automate the parts that are just rules. Built for Alpaca accounts; comfortable with paper first, live when you're ready.
Connect your account — the books keep themselves.
Numyl Investing is trade-management and journaling software, not investment advice, and Numyl is not a broker-dealer. It connects to your own Alpaca brokerage account; all trades and risk are yours. Trading involves risk of loss.
