Release Notes

2026-10-09

New: A Redesigned StocksFast

• A new dark look across the whole site, from the home page to docs, pricing, blog and your account
• The scanner is rebuilt as a workspace: saved scans, examples, watchlists, reference and the assistant sit in one side panel, with results and chart side by side [see: Scanner]
• Run a scan with Ctrl+Enter / Cmd+Enter; scans are checked as you type, so there is no separate Validate step
• Your plan status now shows as a small badge next to your avatar instead of a banner

New Features

• Review mode: step through scan results one chart at a time with j / k, star with s, select with x, and press e to return to editing
• Scanner on phones: a bottom tab bar (Scan, Results, Review, Library), swipe between charts in Review, and a symbol key row above the editor
• Rename a saved scan, edit its description and add or remove tags straight from the editor header
• Watchlists open in their own tab next to your scan: edits save as you go, symbols can be separated by commas or spaces, and "Scan this list" scans that watchlist
• Watchlist symbols display as a filterable set of chips
• Docs, the StonQL reference and function pages have a side nav with instant filtering and Copy buttons on code examples [see: Documentation]
• The examples page has a Contents menu on smaller screens [see: Scan examples]
• Blog posts show a read time and previous/next links [see: Blog]
• Sign-up shows the password requirements as you type

Improvements

• Symbol search puts exact and starts-with ticker matches first
• Visitors trying the scanner without an account now see 5 result rows instead of 3
• Revoking an API key or canceling a subscription is confirmed in place, with no pop-up dialog
• Account emails have a cleaner layout

Bug Fixes

• Subscribers who still had trial days left were shown as on a trial; they now show as Premium
• The "Reset password" button in the password-changed email went to a page that did not exist

New: StocksFast API (beta)

• Run and validate StonQL scans from your own code, and manage saved scans, watchlists and tags over HTTP [see: API documentation]
• Search symbols, browse the scanning universe, and look up every function and field in the catalog
• Create, name and revoke your own API keys under Account → API Keys, each limited to the access you choose

New Features

• Export selected scan results straight to a TradingView watchlist file
• Hover charts now work on touch devices — tap a symbol to open its chart
• Scan credit holders can now scan any historical date, not just the latest trading day

Improvements

• Scan warnings now point to the exact line and column in your scan
• Scan credits are only charged once your results are ready (no charge for failed scan)

• TradingView exports keep share-class symbols in their standard form (e.g. BRK.B)
• Faster page loads: fonts are now served directly from StocksFast

Plan Changes

• Free accounts can view their saved scans, watchlists and tags; creating or editing them now requires a subscription or scan credits.

Bug Fixes

• Fixed scans being charged when market data was temporarily unavailable; these now show a "try again shortly" message
• Fixed a watchlist edit during a data outage leaving the list partially cleared
• Fixed two scans run at the same moment occasionally miscounting scan credits
