## Why PineForge?

- 🎯 **TradingView-exact.** 307 of 311 reference strategies match TV trade-for-trade on the public corpus (the other 4 hold ≥99.9% count parity; 1 further probe is a documented TV-side anomaly at the 1× margin boundary where TV's broker emulator is non-deterministic — engine is correct, and it is excluded from the headline). On a **closed test set** of 415 community-shared TradingView scripts (kept private under TradingView’s Terms of Service — not redistributable), the engine validates **396/396 excellent (100%)** across **~520k trades** — with **19 TV-side anomalies discovered and documented** during that research. **100 of 100** PineForge excellent vs PyneCore + PineTS on the public three-way benchmark (~167,000 TV trades; PyneCore: 85 of 100; PineTS indicator-only).
- 🎯 **TradingView-exact.** 309 of 311 reference strategies match TV trade-for-trade on the public corpus (the other 2 are documented data-resolution / TV-tie residuals; 1 further probe is a documented TV-side anomaly at the 1× margin boundary where TV's broker emulator is non-deterministic — engine is correct, and it is excluded from the headline). On a **closed test set** of 415 community-shared TradingView scripts (kept private under TradingView’s Terms of Service — not redistributable), the engine validates **396/396 excellent (100%)** across **~520k trades** — with **19 TV-side anomalies discovered and documented** during that research. **100 of 100** PineForge excellent vs PyneCore + PineTS on the public three-way benchmark (~167,000 TV trades; PyneCore: 85 of 100; PineTS indicator-only).
- ⚡ **Microsecond-class.** Median **162× faster than PyneCore** across 99 commonly-timed strategies (full 41,307-bar OHLCV, magnifier-on hot loop; see [benchmarks/results/speed.md](benchmarks/results/speed.md)). Parameter sweeps load one `.so` and re-run with new inputs — no recompile, no fork, no IPC.
- 🔒 **Stable C ABI.** 28 functions, one header (`<pineforge/pineforge.h>`). Append-only across minor versions, `static_assert`-pinned struct layouts, hidden-visibility hygiene. Drop a strategy `.so` in any harness; it just runs.
- 🧪 **Reproducible to the bit.** Deterministic float ordering, deterministic bar magnifier, no internal RNG seeded from time. Two runs with the same inputs produce bit-identical trade lists.

PineForge is the **C++ runtime** that PineForge-compiled strategies link against. It implements PineScript v6 strategy semantics — order matching, fills, the magnifier, technical indicators, time/session math — as a static C++ library with a stable C ABI.

The runtime is parity-tested **trade-for-trade against TradingView's "List of Trades" CSV exports** on a reference corpus: **307 excellent + 4 strong of 311 graded** under the canonical verifier (**+1 documented TV-side anomaly**, excluded from the headline). The corpus ships as a **public Apache-2.0 submodule**.

**This is a backtest engine, not a charting library.** PineScript drawing primitives (`plot`, `bgcolor`, `label`, …) compile cleanly but do nothing at runtime. The runtime computes trade execution and reports — it does not render.

**This is not a TradingView clone.** PineForge intentionally diverges from TradingView in a handful of places where TV's behaviour is undocumented or platform-specific (the bar magnifier, deterministic float ordering). Where it converges, it converges **exactly** on the reference corpus (`307/311` excellent + 4 strong; 1 documented TV-side anomaly excluded. Init the public `corpus` submodule per `[CONTRIBUTING.md](CONTRIBUTING.md)`). Where it diverges, it documents the divergence.
