API Keys

Use your API key in the X-Api-Key: <key> header for all API requests to lab.flashalpha.com. To change your password, log out and click "forgot password" at the login page. Your subscription might not immediately display on this page if you recently purchased a subscription, but your permissions should work when using the API.

Risk Engine

Beta note: free on every plan during the beta; at the end of the beta the Risk Engine becomes part of the Growth plan (and above), with notice first. Requests are rate limited to 60/minute per key, and analyzed requests are recorded (key hash, positions posted, results) to guide what we build next.

Upgrade to Growth to arm alerts from templates or your own conditions. Alpha adds formula expressions, universe-wide scans and real-time evaluation.

This feature is not live in this environment yet. The controls below are a preview - they will start working automatically once alerts are enabled for your account.

Daily request limit reached

Your plan's daily API quota is used up, so your alerts may not show until it resets. Upgrade for a higher limit.

An API key is required to manage alerts. Open the tab first.

No templates loaded.

Custom conditions and formulas Alpha

Write your own alert on any screener field and operator, and build custom arithmetic formulas (like atm_iv / rv_20d). Available on Alpha. The templates above are included on your current plan.
