Most "free" trading tools make you hand over an email and confirm a link before you see a single chart. JagSim doesn't. You land on a live demo with no account and no card, and you are placing your first trade in seconds. When you want to save your progress and track your returns, that is when you make a free account.
Every signed-in Paper Trading account starts with a $100k virtual balance that stays with you, portfolios are permanent (no seasons, no forced reset). It's fake money, and that's the whole idea. You can buy a hundred shares of something, watch it move, sell it, and feel exactly what that's like without a real dollar on the line. Want to try before you save anything? Use the free demo first.
The prices you're trading against come from a real-time market feed, not made-up numbers. Search almost any stock ticker or a crypto pair, pull up the chart, and trade it. Because it's a simulator, you're practicing against how the market actually moved, so the mechanics you learn here match how the real thing behaves.
You get the same order types a real broker gives you: market orders, limit orders, stop orders, and you can go short if you think something's headed down. This matters because knowing WHICH order to use is half of trading. Practicing the mechanics (setting a limit price, placing a stop, sizing a position) is a lot less scary when it's virtual money teaching you.
If you've never bought a share in your life, this is a safe place to figure out what any of it means. What's a bid versus an ask? What happens when you set a stop-loss? What does it feel like to watch a position go red? You learn all of that by doing it, not by reading about it, and here doing it costs you nothing.
There's no clock ticking on a trial and no "upgrade to keep trading" wall on the core simulator. Practice as long as you want, come back tomorrow, run it a hundred times. It's a tool I built to help people learn trading without risking cash, and the practice part stays free.
Yes. JagSim is free to use. You can try the live demo without an account or a card, then make a free account to save your portfolio and climb the leaderboard.
No. There's a live demo you can jump straight into and start trading virtual money right away. Signing up just lets you save your portfolio and come back to it.
Neither. It's a simulator with $100,000 in virtual money on real-time market data. You're practicing, so you can't win or lose actual cash, and it's not a brokerage.
That's who it's built for. You can place your first practice trade in seconds and learn the order types, charts, and what going long or short feels like, all without risking anything.
