# Changelog

> New features, changes, and fixes across the Hyperprop platform — APIs, trading engine, webhooks, security, and documentation.

<Update label="August 9, 2026" tags={["Improvements"]}>
  ## API reference: examples and rate limits

  * Every operation across the Platform, Trade, and Market Data references now documents its success responses with realistic examples.
  * Trade API examples show the exact `{success, data, error, code}` envelope the API returns.
  * Every error response now carries a schema.
  * Base URLs in generated code samples always point at production.
  * New [Rate Limits & Quotas](/concepts/rate-limits) page: the Trade API's per-account limits, the exact `429 RATE_LIMITED` retry contract, and webhook delivery quotas.
</Update>

<Update label="August 8, 2026" tags={["Improvements"]}>
  ## Browser access policy

  * Browsers can now call the Trade API, the Market Data API, and the Platform API's user-scoped endpoints only from Hyperprop's own apps or approved partner origins. Enforced via CORS and WebSocket origin checks.
  * Organization endpoints remain open to any origin.
  * Server-to-server calls are unaffected — they send no `Origin` header. **No action needed for typical integrations.**
  * Need direct browser access for a trader-facing frontend? Contact us to approve your origin — a config change, no deploy. Details: [Browser access policy](/introduction#browser-access-policy).
</Update>

<Update label="August 8, 2026" tags={["New releases"]}>
  ## New documentation site

  * Platform, Trade, and Market Data APIs documented in one place, generated from the live OpenAPI specs with an interactive playground.
  * Guides: [authentication](/authentication), [idempotency](/concepts/idempotency), [webhooks](/guides/webhooks) with a signature-verification recipe, and the [MCP connector](/guides/mcp-connector) for AI agents.
</Update>

<Update label="August 8, 2026" tags={["Bug fixes"]}>
  ## Copy trading: partial profit-taking

  * Followers of a leader running a partial scale-out (several take-profits OCO-linked to one stop) now scale out proportionally with each partial fill.
  * Previously the follower's whole position could close at the leader's first target.
  * The protective stop-loss still mirrors at full size.
</Update>

<Update label="August 7, 2026" tags={["New releases"]}>
  ## Trading rules: dollar drawdowns, permission flags

  * `drawdownDenomination` on trading rules: `"percent"` (default) or `"dollars"` — dollars is the right choice for \$0-balance accounts.
  * `drawdownTrailCeiling`: for trailing/EOD drawdowns, the floor locks once it has trailed up to initial balance + this amount.
  * Four informational permission flags shown to traders: `newsTradingAllowed`, `microscalpingAllowed`, `weekendHoldingAllowed`, `overnightHoldingAllowed`.
  * `price` on trading plans is now optional (defaults to 0).

  ```bash theme={null}
  curl -X PATCH "https://api.hyperprop.com/platform/v1/organization/trading-rules/{ruleId}" \
    -H "X-API-Key: hp_live_your_key_here" \
    -H "Content-Type: application/json" \
    -d '{"drawdownDenomination": "dollars", "drawdownTrailCeiling": 100}'
  ```
</Update>

<Update label="August 7, 2026" tags={["New releases"]}>
  ## Account nicknames and a price-alert manager

  * Traders can set a display nickname on any trading account (`POST /trade/account/nickname`, max 32 characters); the real account number stays visible.
  * The chart's Alert button now opens a manager listing every alert — armed or triggered — with one-click delete.
</Update>

<Update label="August 7, 2026" tags={["Improvements", "Bug fixes"]}>
  ## Account details rebuilt + chart data integrity

  * Account view restructured around decisions: progress toward target, risk capacity remaining ("$X left of $Y"), and the rules that apply.
  * Consistency shown in percent, the way firms state it; drawdown mode and trading permissions stated plainly.
  * Metrics that don't apply to an account's rules are hidden instead of showing zeros.
  * Corrupted locally-cached candles can no longer stick to a chart — server history fully replaces the window it covers on every load.
  * A position closed while your connection dropped an update could keep showing as open; the app now re-verifies positions and working orders against the engine every minute.
</Update>

<Update label="August 6, 2026" tags={["New releases", "Improvements"]}>
