The rule-based trading toybox
Build a bot. Test its instincts.
Your next strategy needs a sandbox.
Assemble a rule-based trading bot, run it against historical markets, then watch it trade in paper mode—without putting real cash on the line. Robotrader turns algorithmic trading into a hands-on experiment for curious investors, aspiring quants, and market tinkerers.

The assembly line
From hunch to paper trade.
Start with a market idea, translate it into visible rules, and see exactly what your bot would have done. Every strategy moves through testing before simulation, so you can inspect the logic instead of trusting a mysterious black box.
1. Choose rules
Pick indicators, price conditions, time windows, and assets—no code required.
2. Wire signals
Connect entry, exit, position-sizing, and stop-loss blocks into a readable strategy.
3. Backtest
Replay historical market data, adjust assumptions, and compare results against a benchmark.
4. Simulate
Launch in paper mode, monitor decisions in real time, and learn how the bot behaves between the charts.
Workshop floor
Build bots with quirks—and guardrails.
The Bot Garage is your modular strategy workshop. Snap together logic blocks, set hard risk controls, and give each bot a personality that makes its behavior easier to remember—not easier to mistake for financial advice.
Strategy blocks
Combine moving averages, RSI, breakouts, volume, schedules, and custom rule conditions.
Risk controls
Set maximum position size, stop-loss limits, daily loss caps, and a kill switch before launch.
Robot profiles
Choose a cautious Turtle, twitchy Scalper, or patient Trend Surfer to make strategy behavior visible.
Exportable logic
Save versions, duplicate experiments, and export strategy definitions on eligible plans.
Debug the hype
The chart is not the whole story.
Performance Lab puts returns beside the risks that produced them. Review drawdown, win rate, volatility, trade history, and benchmark comparison so a lucky backtest does not get promoted to genius too quickly.
Returns
See cumulative and annualized performance across the selected test period.
Drawdown
Find the deepest decline and how long the strategy took to recover.
Win rate
Compare winning trades with average win, average loss, and payoff ratio.
Benchmark context
Stack your bot against buy-and-hold results and account for fees, slippage, and data limits.
Friendly competition
Trade ideas. Not bragging rights.
Robot League is a community gallery for experiments, challenges, and shareable results. Publish a bot’s rules and paper-trading record, compare like-for-like metrics, and keep the leaderboard focused on transparent process—not promises of profit.
Public bot gallery
Browse community strategies by market, timeframe, risk profile, and backtest period.
Strategy challenges
Enter themed paper-trading competitions with fixed starting balances and visible rules.
Leaderboards
Rank by risk-adjusted results, consistency, or drawdown—not raw returns alone.
Result cards
Share a clean snapshot of rules, test dates, benchmark, return, and maximum drawdown.
Choose your loadout
Start free. Scale the experiment.
The free plan gives you a practical place to learn: core rule blocks, limited historical data, backtesting, and paper trading. Paid tiers add deeper data, advanced tests, more simultaneous bots, alerts, strategy exports, and—where supported—connections to live brokerages.
Free Garage
Build core bots, run limited historical backtests, and paper-trade with essential performance metrics.
Pro Workshop
Unlock deeper history, advanced backtesting, more active bots, alerts, richer analytics, and strategy exports.
Broker Connect
Link an eligible brokerage only when you are ready; availability, fees, permissions, and supported assets vary by provider.
Clear limits
Backtests can overfit. Simulated fills may differ from live markets. Historical results do not predict future performance.
Responsible by design
Robotrader is an educational and simulation platform, not investment advice. Never risk money you cannot afford to lose, and review every automated strategy before connecting a live account.
