Strategy Arena Lab · Windows · Free

See if your strategy beats Buy & Hold. Keep the holdout sealed.

Assemble Ride SMA20, dual SMA, Event Proof OR/AND or Turtle, then Play the tape: close, equity, Buy & Hold and SMA200 on one chart. Think lets CUDA search the train; Rust CPU checks the winner. KEEP is only possible after Judge opens the sealed 20%. No account. No live trading. Paying never greens a verdict.

Version 0.1.0-123 · build of 21/08/2026

New in this Windows beta: Wide Think explores SMA, momentum and event companions on the train, then CPU-checks the winner. Judge remains last and the sealed 20% stays closed.

How the proof stays honest

Pine is an import bridge for deterministic subsets; Strategy Arena generates and measures ArenaScript first. Rust CPU is the final verification authority, CUDA only accelerates search, and INCONCLUSIVE remains a valid scientific outcome.

Official public beta channel. Local quick proofs and JSON export are free. No broker connection and no live orders. Integrity is by published SHA-256 (this channel may be unsigned until the Windows signing gate clears).

First session

Play the tape. Then think. Judge last.

A train result is not KEEP. Silver Buy & Hold can print near +99% on the frozen tape — you have to see it.

01 · ASSEMBLE
Ride SMA20, dual SMA, Event OR/AND or Turtle

Ride SMA20 and dual-SMA oil let winners run without a take-profit. Event Proof keeps its OR seed and adds an AND companion; Turtle uses a Donchian-20 breakout. The 73 public fighters stay a strategy dictionary.
02 · PLAY
See strategy versus Buy & Hold

One chart: close, strategy equity, Buy & Hold, SMA200, cash, trades, and a curtain on the sealed 20%. Three bosses: cash, the tape, SMA200. Play never opens holdout.
03 · THINK, THEN JUDGE
CUDA searches the train. CPU judges. Holdout last.

Think ranks neighbours that beat Buy & Hold on the full train, then checks internal folds. overfitSuspect is a success, not a failure. KEEP / REJECT / INCONCLUSIVE only after Judge. TradingView stays optional and never buys a greener verdict.

Inside the app

See the Lab before installing

Play the frozen tape against Buy & Hold before any KEEP. Rust CPU still judges.

Strategy Arena Lab Play chart: strategy equity versus Buy and Hold with sealed holdout curtain — **See the tape**Gold is Buy & Hold / close. Green is the strategy. Blue is SMA200. The right curtain stays sealed.

Three bosses panel showing strategy, cash, Buy and Hold tape and SMA200 on silver train — **Read the three bosses**Strategy and the Buy & Hold tape are both numbers. Alpha alone is not the story.

Bounded Agent Control view for a local strategy proof — **Keep agent control bounded**A local proof can run without broker access or live-trading permission.

Native Rust Monte Carlo diagnostic in Strategy Arena Lab — **Add uncertainty context**Monte Carlo remains a diagnostic after selection and never replaces the holdout.

After Judge

FAQ

Before your first run

Is an NVIDIA GPU required?

No. The CPU reference engine works without a compatible GPU. CUDA is used only when it is available.

Do Play or Think open the holdout?

No. Play and Think stay on the train. KEEP / REJECT / INCONCLUSIVE exist only after Judge opens the sealed 20%.

Where does my data go?

Backtests stay on your machine. Synchronization starts only after you explicitly sign in and choose to sync.

Why can SmartScreen show a warning?

The current beta may be unsigned. Use the official installer link and compare its SHA256 with the value published above.

Is this a live trading robot?

No. Strategy Arena Lab is an educational research and backtesting tool. It does not place broker orders or provide investment advice.
