Local and private: no account for the first proof

100 measured variants; final 20% stays unseen until selection

CPU authority, CUDA acceleration when verified, reproducible report

One run becomes one auditable Lab Report

The report binds the strategy, dataset, measured search, sealed holdout and engine receipt before any chart review.

1. Choose the source

Replay a public Arena strategy, paste supported Pine or generate a native ArenaScript candidate.

2. Measure without peeking

Search on the training window while the final 20% stays sealed. CPU remains the authority; compatible CUDA accelerates search.

3. Decide from evidence

Read the holdout verdict, uncertainty diagnostics, Run ID and reproducibility receipts before keeping or rejecting the candidate.

Technical compatibility: supported, partial and rejected Pine features

Pine compatibility without losing the ArenaScript engine

The Lab is not a TradingView extension. It generates and backtests Strategy Arena ArenaScript strategies first. Pine is an import bridge for deterministic subsets; CPU reference is the truth source, then CUDA runs only when a script maps to current kernels.

Supported ArenaScript generation, native generated composites, strategy.entry, SMA/EMA/WMA/HMA/ALMA/VWMA/RMA crossover/crossunder/cross and price-vs-MA crosses, Stochastic, CCI, ROC, CMO, ta.change, ta.mom, Williams %R, ADX, MFI, OBV, Bollinger, Keltner, SuperTrend, Parabolic SAR, Linear Regression, VWAP, WMA Cross, HMA Cross, ALMA Cross, VWMA Cross, ATR, Donchian, numeric inputs Native Strategy Arena candidates, generated native families and compatible Pine signals map into CPU reference runs, sweeps and current CUDA paths, including direct ta.crossover/ta.crossunder/ta.cross, inline ta.sma(close, fast), ta.ema(close, fast), ta.rma(close, fast), ta.stoch, close-based ta.cci, ta.roc, ta.cmo, ta.change close momentum gates, ta.mom close momentum gates, ta.wpr, pure ta.dmi ADX threshold plus ta.crossunder/ta.crossover/ta.cross gates, DMI plusDI/minusDI direction gates, close-based ta.mfi money-flow gates, oscillator ta.crossunder/ta.crossover/ta.cross threshold gates, ta.obv(close, volume) volume momentum gates and assigned or inline threshold plus ta.crossunder/ta.crossover/ta.cross gates, ta.vwap(close) assigned or inline price gates plus close crossover/crossunder VWAP gates, ta.bb tuple bands and inline ta.sma(close, length) +/- ta.stdev(close, length) * mult formulas plus close crossover/crossunder band gates, ta.kc tuple channels and inline ta.ema(close, length) +/- ta.atr(length) * mult formulas plus close crossover/crossunder channel gates, ta.supertrend line gates, close crossover/crossunder line gates and direction < 0 / > 0 gates, ta.sar, ta.atr and Donchian gates including short-form ta.highest(length)[1] / ta.lowest(length)[1].

Partial RMA composite, OBV composite, HLC3 sources, oscillator + EMA/regime composites, short entries, named exits, input.source(close), legacy input(close), volume SMA gates, staged broad CUDA families Accepted for Lab Reports with CPU reference, pure native signal paths when the Pine subset is deterministic, and staged CUDA full-plan paths for mixed strategies.

Rejected request.security/request.financial, non-close sources, strategy.order/risk, broker state, barstate/timeframe, arrays/maps, loops, alerts, drawings Repair path: flatten to one local bar stream, replace broker/runtime state with explicit ArenaScript entry, exit, stop, take-profit or timeout rules, then rerun CPU/CUDA research.

Can I use the Lab for free?

Yes. The first local proof, sealed holdout, Lab Report review and JSON export remain free without an account or card.

What exactly do Builder and Operator sell?

Builder preserves reports and versions. Operator adds bounded supervised AI campaigns. Neither plan changes the verdict or the evidence.
