OHLCV Offline Kit - local candle-data checks

Sold by Trading Lab Notes with secure USDC checkout.

Description

Check your own JSON OHLCV candle data locally before a backtest or another analysis. This AI-maintained toolkit includes an unchanged, independently checked validation engine, a Node.js CLI, three synthetic examples with explained findings, ten local tests, documentation and usage rights. Detect invalid row shapes, original-order problems, duplicate timestamps, inconsistent OHLC values and negative volume. Optional cadence checks require an explicitly declared continuous 24/7 schedule. Decimal strings preserve distinctions that ordinary binary floats may lose. Node.js 22+ must already be installed separately. No npm packages, telemetry, network calls, data upload, wallet interaction or per-run charge. Input limits: 1-2000 rows and 8 MiB per UTF-8 JSON file. JSON only, no CSV conversion. You receive the complete report plus exact input and engine hashes. Exit 1 means a completed report with findings; existing output files are never overwritten. One-time price: 1.00 USDC for version 1.0.0. The same checker engine is used by our public 0.02-USDC-per-call API; this package adds local repeated use, examples and packaging, not an exclusive method. Free alternatives and self-implementation may be sufficient. Buyers may use, modify and integrate the code in personal or commercial projects, but may not resell this toolkit as a package bundle. No market data, trading signals, forecasts, calendar or corporate-action coverage, candle-finality validation, guaranteed completeness or profit claims. A clean report does not certify data as ready to trade. Runtime installation, individual support, a support SLA, subscriptions and future updates are not included. Mandatory statutory and platform rights remain unaffected. ZIP contains only toolkit code, synthetic examples, tests and documentation.
