100 local variants, sealed 20% holdout, Lab Report and JSON export.
Local Windows strategy research
Strategy Arena Lab
Test a strategy locally. Keep only what survives sealed unseen data.
Free tests. Builder keeps your evidence. Operator lets an AI run bounded campaigns under your control.
One free proof. Two paid workflows.
Start without an account or card. Upgrade only when you need continuity or supervised AI research.
Private report history, saved strategy versions and reusable proof exports.
Bounded supervised campaigns, batch research capacity and additional local evidence runs.
Every plan uses the same verdict, sealed holdout and uncertainty evidence. Payment never improves a result.
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.
What is Strategy Arena Lab?
Strategy Arena Lab is a free desktop app for Windows and Linux that replays a Pine Script strategy on past data. It compares trades one by one with TradingView, counts every variant tried, then a judge returns a verdict on a period kept sealed: survives, mirage or inconclusive. The Lab places no orders and runs locally.
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.
What is a sealed period in the Lab?
It is the end of the history that the search cannot read: the seal is written to disk before any computation. The judge opens it only once, after selection, to return the verdict.
Does the Lab compare trades with TradingView?
Yes, for supported Pine the Lab rebuilds the same rules and compares its trades one by one with TradingView's list of trades. The exported Pine is exactly the strategy that was judged.
Which operating systems does the Lab run on?
The Lab runs on Windows and Linux; the Linux build uses the CPU engine and the full interface has not been tested on Linux. Linux packages are provided as AppImage and .deb, with start-up checked on Ubuntu.
Which verdicts can the Lab return?
The judge returns KEEP, REJECT or INCONCLUSIVE, shown as survives, mirage or inconclusive. INCONCLUSIVE remains a valid result, for example when there are not enough trades to judge.
Can the Lab place orders?
No, no Lab tool places an order, opens TradingView, publishes anything or starts a payment. Strategies, data and results stay on your machine.
