Trend
Follow the direction of the market and filter out choppy periods.
Features
Build a strategy, test it honestly, run it on your own machine.
A visual strategy editor with 22 indicators, a backtest engine with institutional risk analytics, and a desktop client that trades on your exchange account while your keys stay with you.
Strategy editor
22 indicators, combined without writing code
Each rule reads like a sentence: "If RSI 14 is below 30, buy with all cash". Indicators are built in: there is no code to write or maintain.
Momentum
Spot overbought and oversold conditions and the strength of a move.
Volatility & statistics
Size stops to the market's movement and catch breakouts or stretched prices.
Volume & market data
Confirm moves with participation, derivatives positioning and market sentiment.
Conditions
And, or, not, comparisons, "is between", price N bars ago, highest and lowest over a period.
Orders & sizing
Buy with all cash, a percentage or a fixed amount; sell all or part of a position; close a position.
Risk management
Stop loss, trailing stop and take profit in percent or price, plus a risk / reward target.
Tunable parameters
Mark any value as a parameter with a range, then let the optimizer test every combination (Pro).
Backtesting
Know how a strategy behaves before risking money
Backtests run in our cloud on historical candles, with fees and realistic order execution. The report shows not only what you would have made, but how much risk it took and how much was luck.
Realistic simulation
Trading fees on every fill, a configurable execution delay, and stop loss or take profit triggered inside the candle, not only at its close.
Markets without a bias
Besides real crypto pairs, test on three synthetic markets that behave like crypto but have no built-in trend (flat, +10% and −10% a year). A strategy that only works because Bitcoin went up shows it here.
A full risk report
Equity curve, drawdowns and every trade, with the ratios professionals use to judge a strategy, and a Monte Carlo test of how much the result depended on the order of trades.
In every report
- Price chart with trades, equity curve and drawdown
- Monthly returns table and comparison with buy and hold
- Seasonality by hour, weekday, day of month and month
- Monte Carlo: range of outcomes and drawdown probabilities
- MAE / MFE: how far trades went against and for you
With Pro
- Parameter optimization with a stability heatmap
- Multi-asset tests on several markets at once
- Value at Risk and expected shortfall (95% and 99%)
- Beta and alpha against Bitcoin, Omega and Ulcer ratios
- Trading cost breakdown: fees versus slippage
Backtests use historical data and simulated execution. They do not predict future returns.

Your keys stay on your device
Exchange API keys are stored encrypted on your machine, protected by a passphrase only you know, and are never sent to our servers.
Signed, encrypted strategies
Strategies sent from the Web Lab are encrypted and signed, so the client only runs strategies that really come from Control Trading Lab, and loads them in memory only.
You stay in control
Start, pause and stop bots from the Web Lab once you allow remote control on the client. It is off by default, and a kill switch always works.
Runs around the clock
Daemon mode keeps strategies running on a server or VPS, with automatic reconnection to live market data.
Optional telemetry
Share balances and bot status with your Web Lab dashboard only if you turn it on.
One-line install
Install on Windows, macOS or Linux with a single command, then link the client to your account.
Plans
Start free, upgrade when you need more
You can try the Lab without an account. Paid plans are coming soon.
