The product
From idea to broker, in one application.
Build visually or in code, validate on years of data, export to your platform. Each module flows into the next.
Export
Ready for your broker.
Native generation from a script or Blueprint graph. Parameters exposed as inputs.
- MetaTrader 4 MQL4
- MetaTrader 5 MQL5
- cTrader cBot C#
- TradingView Pine Script v5
Optimization
Parameters that hold out of sample.
Genetic, CMA-ES, successive halving, walk-forward, and a 0–100 robustness score.
Neptune AI
Agents that explore, test, and iterate.
Local or external Chat AI from Free. Discovery generates hypotheses, backtests them, and iterates: 2 iterations / 1 tree on Free, 50 / 10 on Essential, unlimited on Pro.
Money management · prop firm
Prop firm rules, enforced by the engine.
Type #add money in a script: Risk %, max daily and total drawdown, profit target, kill-switch after consecutive losses, cooldown. The engine sizes each order from its stop-loss and stops the strategy when a limit is hit: in backtest and optimization. Available from Essential.
Terminal
Multi-chart, multi-timeframe.
2×2 layouts, Watch, Seasonality, Multi-TF. Compare without leaving the session.
Portfolio
A desk view of your accounts.
Weighted Sharpe and PF, worst drawdown, exposure, trading journal.
Privacy
Local-first by design.
Your data, strategies, and models never leave your machine. Zero cloud data, zero orders sent to a broker.
- No telemetry

Chart analysis
54 built-in indicators.
And yours.
Moving averages, momentum, trend, volatility, volume, structure: all computed in Rust, on the chart and in the engine. Missing one? Import it or write it in Rust, C#, or Python.

Yours, too. Import a file into Indicators/ or write an indicator in Rust, C#, or Python (single or multi-output): compiled, overlaid on the chart, and usable in your strategies like the built-ins.
Drawing
Draw, snap, lock.
Trend, ray, horizontal, vertical, rectangle, and Fibonacci (3 level models). OHLC snapping, named layers, hide and lock.
Chart patterns
32 patterns detected and annotated.
20 candlestick patterns (doji, hammer, engulfing, morning and evening stars…) and 12 chart patterns: double top / bottom, head and shoulders, triangles, wedges, flags, ATR-based flat range: marked on the chart.
Market regimes
7 regimes, calibrated on your data.
Range, mean reversion, compression, bullish or bearish trend, bullish or bearish breakout. Structural timeline, P&L by regime, and a #add regime line to trade only in selected regimes.
Engine
A Rust engine.
Three languages.
Bar-by-bar simulation with spread, slippage, commissions, latency, and funding fees. Same engine, same 7.7 million M1 bar series, same simple strategy: only the strategy language changes.

Methodology and measurement conditions
Measured on 09/08/2026 on Intel Core i7-13700F, Windows 11, engine v2 release build (run_backtest_v2), synthetic M1 series, strategy hosts from the app (host_rust, host_csharp, host_python). With a SMA 10 / 30 crossover and 61,361 simulated trades, the same Rust backtest takes 7.4 s (1.04 M bars / s). Times vary by machine and strategy complexity.
