What is PineForge?

PineForge is an open-source PineScript v6 backtest engine. It transpiles Pine to C++ and runs deterministic, byte-reproducible backtests on your own OHLCV data — validated trade-for-trade against TradingView at 245/246 strict parity (0 engine bugs, ~375k trades across a 246-strategy corpus). Free via hosted MCP at mcp.pineforge.dev (no install, no key, 100 backtests/week) or local Docker container; your code and data never leave your machine.

Try the free MCP · join the Studio waitlist

Backtest your Pine from Claude — free, no key.

Your strategy backtests perfectly on TradingView. You deploy it live — the trades don't match. PineForge fixes this: deterministic, byte-reproducible, on your own data.

A free hosted MCP endpoint at mcp.pineforge.dev — point any MCP client at it, no install. Or run it locally via Docker on your own data.

Free hosted MCP live now (100 backtests/week). Local Docker also free for personal trading. Studio launches Q4 2026.

Drop your email for early access to Studio. You'll get the launch email when Optuna optimization ships (Q3 2026), plus first access to the cloud IDE (Q4 2026). We'll also send you the 246-strategy validation report.

Why PineForge

Three things TradingView’s runtime won’t give you.

01 / DETERMINISM

Same script, same data, same trades. Byte-reproducible.

02 / SPEED

Native C++. 50k bars in tens of milliseconds.

03 / OWNERSHIP

Your data, your machine, your strategy. Offline by default.

One runtime that occupies a corner no one else does.

Capabilities

Five things you can’t do on TradingView alone.

shipped

Bring your own data

Run any custom data — daily, intraday, alt — without TradingView's symbol restrictions.

shipped

Intra-bar resolution at any cadence

Walk inside the bar with sub-bar resolution. No more last-tick approximation.

building Q3 2026

Optuna with a custom objective

Optimize with any objective function — Sharpe, drawdown, profit factor, your own.

building Q3 2026

Forward-test with TradingView-shaped webhooks

Walk-forward analysis built in. Out-of-sample is the default, not an afterthought.

designed 2027

Strategy marketplace · sell compiled .so

Sell compiled .so. Time-bound, machine-bound, broker-bound — set by you, not by a platform.

Bring your own dataexpand

Any OHLCV CSV — your tick data, your custom feed, your alternative-asset history. Run offline, in CI, in Docker. No upload, no API key.

Intra-bar resolution at any cadenceexpand

Six distribution modes (uniform, cosine, triangle, endpoints, front/back-loaded), optionally volume-weighted. A limit at $100 inside a 95–105 bar fills at exactly $100 — TradingView’s bar magnifier without the subscription.

Optuna with a custom objectiveexpand

Sharpe, Sortino, drawdown, profit factor — or any one-line lambda you want the optimizer to chase.

def objective(report):
  return 0.6 * report.sharpe - 0.3 * report.max_dd + 0.1 * report.profit_factor

Forward-test with TradingView-shaped webhooksexpand

Drop-in replacement for TradingView alerts. Same JSON shape, same runtime as your backtest — no rate limits, no replay drift.

Strategy marketplace · sell compiled .soexpand

AES-256-GCM-encrypted shared library. Ed25519-signed, machine-bound, time-bounded licenses. Buyers tune the inputs you expose; they never see the source.

The 15-strategy PyneCore gap is consistently in bracket / trail / partial-exit semantics, where PyneCore’s broker emulator differs from TV. Three canonical examples: 06-liquidity-sweep, 07-scalping-strategy, 49-partial-exit-qty-percent. See the per-strategy breakdown →
