v0.28.0

v0.28.0

This release fixes incorrect market routing, fractional execution loss, incomplete account responses, and missing continuation support. It also adds LS common order management for tracked domestic orders.

Upgrade notes

• Balance availability: unsupported metrics are listed in unavailable_fields and omitted from HTTP JSON instead of being reported as zero or filled with a different financial metric. Go callers must check UnavailableFields. This affects Toss cash/withdrawable cash/total assets and LS cash/buying power/withdrawable cash. LS total assets now use the provider's estimated net assets.
• Account summaries: /accounts/summary returns HTTP 503 without partial totals when any account fails or cannot supply a required aggregate metric.
• Fractional quantities: prefer filled_quantity_decimal, remaining_quantity_decimal, and fill quantity_decimal when present. Whole-share compatibility fields remain available.
• LS raw Go responses: numeric values are decoded as json.Number to preserve large order identifiers and quantities. HTTP values remain JSON numbers.
• LS order management: cancel, modify, order lookup, and fills are available for domestic orders placed through this account's common API with recorded credentials and the same Korean trading date. Unknown or prior-day orders are rejected; use the raw APIs for other scopes. Cancellation acceptance is not confirmation of completion.

See the common API contract for migration details and pagination examples.

Fixes and additions

• KIS domestic placement, modification, and cancellation forward the requested exchange with current TR identifiers. Unsupported sandbox venues are rejected.
• KIS overseas candles use the correct overseas endpoint. Date-range queries paginate with explicit limits, and position-source failures no longer become successful empty holdings. The documented sandbox bond limitation is handled separately.
• Restore 106 optional KIS request properties in generated SDK types and OpenAPI documentation.
• Kiwoom quote and chart requests use venue-specific NXT/SOR symbols, validate conflicting inputs, and use documented account query and withdrawal fields.
• Add optional Go page interfaces and HTTP continuation headers for Kiwoom and LS while retaining existing raw response bodies. Common holdings and chart queries reject incomplete traversals; Kiwoom charts stop once the requested range or limit is covered.
• Preserve Toss fractional executions and calculate remaining quantities without a floating-point round trip. Daily changes use the previous trading-session close in the exchange's timezone.
• Correct Toss and LS balance field meanings and propagate upstream failures.
• Add LS account, credential, and trading-date guards for common order management, exact order identifiers, and bounded order/fill history traversal.
• Prevent failed or delayed LS reauthentication and stale automatic refreshes from replacing the active account identity or token.

KIS, Kiwoom, and Toss WebSocket support and Kiwoom common US/minute-chart expansion remain outside this release.

Validation

• Full race-enabled test suite, plus an additional LS race suite after the final authentication changes.
• Static analysis, vet, binary build, generated broker spec checks, and OpenAPI consistency checks.
• Isolated build of the existing kis-requester consumer against this library.
• Regression tests use local mocked providers; no live orders were submitted.

Full changelog: v0.27.0...v0.28.0

v0.27.0

The spec drift check now handles transient Kiwoom and LS documentation failures with bounded retries and reports each broker independently, preserving refresh logs and diffs when any broker fails.

• Remove Kiwoom ka10087 and ka10098 from active documented endpoints following the official retirement notice, effective September 12, 2026 at 21:00 KST. Existing exported Go constants and payload types remain available with deprecation comments for source compatibility.
• Refresh LS chart and ETF documentation, including KRX pre/after-market times and NXT fields. Existing required inputs and the endpoint inventory are unchanged.
• Update the Toss candle timestamp description: one-minute timestamps identify the candle end; daily timestamps identify the trading date.
• Regenerate the published OpenAPI document.

Validation: all generated spec and OpenAPI checks, full Go race tests, go vet, build, golangci-lint, and workflow syntax/failure-path checks passed locally. Remote CI and CodeQL passed. The live spec drift check refreshed all four brokers successfully with no diff.
