Questions

Quick answers about prices, fees, AI and cost.

Is Papertrade really free?

Yes. Create an account with your email and start trading. There's no credit card, no trial period and no paid plan you need to unlock.

Is any real money involved?

No. Every simulator runs on virtual money. Nothing is sent to a real broker or exchange, so you can't lose anything.

Where do the prices come from?

Live and historic prices come from public market data (Yahoo Finance, and Zerodha Kite for India where it's connected). Some exchanges' free feeds run up to 15–20 minutes behind. Replays use 1-minute candles for roughly the last month, 5-minute candles for about two months and hourly candles for up to two years.

Which AI apps can I connect?

Any app that supports MCP (Model Context Protocol), including Claude, Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf, Gemini CLI. The Connect AI page has step-by-step setup for each one.

How accurate are the broker fees?

India and US brokers use their published rate cards, plus statutory charges. Other markets use each broker's typical online commission and the market's main transaction taxes. Rates marked "about" are close estimates, so check your broker before relying on an exact number.

Can I practise when the market is closed?

Yes. Replay any recent trading day at any time, at up to 120× speed. Live simulators accept orders only while their exchange is open.

Your next trade can be practice.
