Practice with a fully simulated portfolio and an automated paper-trading bot that runs your strategies on a schedule — all the discipline of live trading, none of the risk.
Live-market decisions, zero real-money risk.
The paper-trading simulator lets you practice real, in-the-moment decisions with a built-in Practice account funded with $100,000 in virtual cash. Place market and limit orders on stocks and crypto, buy simulated calls and puts, manage risk, and build habits — without a dollar on the line.
Replay challenges let you trade famous market episodes bar by bar, from the 2020 crash to hourly 2025 shocks, and score your discipline against a buy-and-hold benchmark.
An automated paper-trading bot can run your enabled strategies as a weighted ensemble on a schedule, so you can study how a disciplined system behaves over time.
Market & limit orders with realistic slippage, fees, and risk checks — no broker needed.
Trade historical episodes bar by bar and get an A–F grade plus an AI Coach review.
Runs your strategy ensemble on a schedule with full idempotency and safety.
Kill-switch, order caps, and a daily-loss halt keep the simulation disciplined.
Practice 24/7 — the bot handles due-bar timing across timeframes.
The bot consolidates every risk cap into each order it simulates: position size, per-trade risk, portfolio exposure, and buying power. You see exactly what a rules-first system does when emotion is removed.
