GreekSentry Dashboard for a demo portfolio: SPY beta-weighted delta, gamma, theta and vega totals, the live stress monitor at minus 2, minus 1, plus 1 and plus 2 percent, and risk status alerts

Why GreekSentry

Risk visibility without the noise.

Options portfolios get complicated when expirations, strikes, and market moves overlap. GreekSentry makes that exposure easier to inspect.

See the whole picture

Review Delta, Gamma, Theta and Vega at the portfolio and underlying level without switching between broker screens.

Keep expiry in view

Surface 0DTE, 1DTE and later expiration exposure separately, so short-dated risk is more visible.

Explore what-if risk

Examine modeled price and volatility shocks, concentrated positions, and distance to short strikes.

Product capabilities

Purpose-built for options risk.

Five connected views. One consistent focus: understanding exposures rather than recommending trades.

  • 01Risk Dashboard

    Portfolio Greeks, a four-direction stress monitor, risk status, and directional exposure views using raw and estimated SPY beta-weighted Delta where available.

  • 02Positions

    Individual options and strategies, per-underlying totals, expiration context, and closest short-strike visibility.

  • 03Expiry Risk

    Examine short-dated exposure separately, including 0DTE and 1DTE contracts and expiry-based risk grouping.

  • 04Scenario Lab

    Explore hypothetical underlying moves, changes in implied volatility, and position adjustments using modeled outcomes.

  • 05Risk Alerts

    Set portfolio and underlying risk thresholds. Receive desktop alerts, with optional Discord/webhook delivery.

Model limitations: calculated Greeks and scenario outcomes are estimates. Quote quality, missing data and model assumptions can affect results.

Broker connectivity

One view across supported accounts.

GreekSentry connects to brokerage data through configured account integrations; availability and permissions vary.

  • tastytradePrivate beta integration
  • RobinhoodIntegration available in beta; distribution permission pending

Broker names are descriptive only and do not indicate partnership, approval or endorsement. Broker authorization grants may permit broader actions than GreekSentry performs.

Security & privacy

Local-first by design.
Transparent about the boundaries.

We believe risk tools should clearly explain where calculations run, how they connect to brokers, and when information leaves the device. Read the Privacy Policy.

  • Risk calculations on your computer

    Core portfolio calculations run locally in the desktop application; broker data still requires network requests.

  • Read-only application behavior

    GreekSentry is designed for monitoring and does not submit, change or cancel trades.

  • OS-backed credential storage

    New credentials use supported operating-system credential storage. Older installations may require separate review or migration.

  • Respectful broker polling

    Data is polled, not continuously streamed. Connections include batching and retry/backoff handling for broker API limits.

  • Optional external notifications

    When enabled, Discord or webhook alerts transmit alert details to a third-party destination you configure.

  • Model-based estimates

    Greeks, stress tests and scenario values depend on market data and model assumptions, and may differ from broker figures.

Important information

GreekSentry is a software risk-monitoring tool—not a broker, trade-execution platform, investment advisor or source of investment recommendations. Model-based Greeks, stress tests and scenarios are estimates, not predictions or guarantees. Broker and market data can be delayed, unavailable or incomplete. Options trading involves substantial risk.
