Live demo — switch tabs, drag the Monte-Carlo slider. Research & education only; not investment advice.

Real data. Real fills.

Daily bars for US stocks, ETFs, crypto and futures, out of the box — with realistic fills and costs, not a toy simulator. Options and intraday are on the roadmap.

From idea to a tested edge

Wire up a strategy from price, indicators and risk rules, compile it to real code, and pressure-test it with backtests and out-of-sample tests on real daily market data.

01
Build

Drop price, indicators (RSI, MACD, moving averages), conditions, risk rules and entry/exit signals onto the canvas, or describe the setup in plain English.

02
Compile

Your graph compiles deterministically into a runnable strategy. Every rule is made explicit, with no lookahead and no black box.

03
Backtest

Run it on real daily market data with realistic fills and costs, then read the trade log, equity curve, Sharpe and drawdown.

04
Walk-forward

Re-test out-of-sample across rolling windows, the honest check that separates a real edge from a curve fit.

05
Test out of sample

Re-run on a held-out window, tweak nodes, and re-run again — the honest check that a result isn't a curve fit, all in one workspace.

A quant desk, visually

Indicators, cross-overs, regime and risk rules, position sizing and stops. The building blocks of a systematic strategy on one canvas.

Tests you can trust

A deterministic compiler, a no-lookahead guarantee, and walk-forward folds. Basket pooling turns a thin single-symbol sample into one you can actually judge.

Bring your own keys

Daily market data out of the box. Add Polygon/Databento/Tiingo for deeper data, or any LLM for the copilot. Your keys, encrypted, never ours.

One hosted workspace

Chat copilot, node canvas, backtest terminal and out-of-sample tests in a single hosted space. Nothing to install, and no services to run yourself.
