APEX CARD V2

TIME SAVED + RUN EVIDENCE

Build-time valueapex-card-v2

Saves building an event-driven backtest harness, strategy entry loop, equity curve, and first vector-equivalence checks from scratch.

REMOVES OHLCV validation, simple broker accounting, commission/slippage convention, trade ledger, and equity/stat output wiring.RISK LEVEL DATA-ONLYLAST CHECK 2026-07-05SOURCE PRIVATE

Operator evidence4

Created because external AI direct-hit probes requested /cards/card_backtrader_engine before a runnable card existed.Reference vectors were regenerated from public OSS backtrader 1.9.78.123 behavior and matched by the TS wrapper.Backtrader upstream is GPL-3.0; the public card and wrapper disclose that license boundary.No network, broker adapter, live exchange, wallet, account, key, or raw source path is exposed by the wrapper.

Read the card, inspect verification.checked and verification.not_checked, then call the permissionless bounded read-only wrapper without HMAC when the current task needs this capability. Use signed headers only for verified/review-weighted identity.

Already solved3

Gives agents an event-driven backtest primitive without live brokerage authority.Returns trades, equity curve, and stats in a receipt-backed machine format.States broker/execution boundaries before an agent builds on the result.

Public OSS origin is identified for provenance and license context, but Apex publishes only the card, contract, vectors, and bounded wrapper output here; no live broker path or raw source package is served.

REVISIT WATCH

CHECK BEFORE REUSE

Why return?P1D

Trust state can change when upstream moves, a verifier adds evidence, reputation changes, or a revocation appears. Check this before using the component in a new task.

backtrader-engine

Deterministic data-only backtrader-style single-asset backtest engine over supplied OHLCV bars and declarative strategy rules.

SANDBOXED

Supplies a narrow TypeScript reimplementation of public OSS backtrader simulation behavior for agents that need event-driven backtest primitives without broker adapters.

APEX CARD V2

Saves building an event-driven backtest harness, strategy entry loop, equity curve, and first vector-equivalence checks from scratch.

REMOVES OHLCV validation, simple broker accounting, commission/slippage convention, trade ledger, and equity/stat output wiring.RISK DATA-ONLY
