JagSim is a free day trading simulator. Practice the speed and mechanics of intraday trading with $100k in virtual money on real charts. It's for building skill, not for making money.
Real day trading happens fast. You're reading a chart, deciding, and getting an order in before the moment's gone. Most of that is mechanics: knowing where the buy and sell buttons are, picking the right order type without thinking, and sizing a position in a couple of clicks. A day trading simulator lets you drill that part over and over with virtual money, so the mechanical stuff becomes automatic and you're not fumbling the ticket when it counts. The goal here isn't to predict the market. It's to make the act of trading feel routine, so your attention goes to the decision instead of the buttons.
Every session starts you with a $100,000 virtual balance. Because none of it is real, you can take a hundred trades in an afternoon just to get comfortable. Enter, exit, enter again. Practice a fast scalp, then practice waiting. If you fat-finger an order or blow up the balance, reset and go again. That freedom to repeat, and to mess up with zero cost, is the whole point of practicing intraday trading in a simulator instead of a live account.
Day trading lives and dies on order entry, so you get the same order types a real broker gives you. Practicing which one to reach for is half the skill:
Learning the mechanics of each (setting a limit price, placing a stop, flipping from long to short) is a lot less stressful when it's virtual money teaching you the buttons.
You're trading against real market data, not made-up numbers, so the way price moves matches how the real thing behaves. One honest note: prices are real-time, but the chart refreshes about once a minute rather than streaming every tick, so this isn't a tick-by-tick scalping terminal. It's built for practicing the mechanics and the decisions, placing orders, managing a position, reading structure, without needing a funded account or a paid terminal. The muscle memory you build here carries over to the real interface.
The part that separates careful traders from reckless ones is what they do before entering: how big is the position, and where's the exit if it goes wrong. In the simulator you can practice setting a stop every single time, sizing so one trade can't wreck the account, and actually watching a position go red so it's not a shock later. None of that costs you a cent here, which is exactly why it's a good place to build the habit.
Here's the straight version: day trading is genuinely hard, and plenty of people who try it with real money lose it. This simulator won't change that, and it can't make you money because there's no real money in it. What it can do is let you build familiarity with the tools, the order types, and your own reactions, so you're learning the mechanics on virtual money instead of paying tuition to the market. It's an educational tool, not investment advice and not a brokerage.
Yes. Paper trading with virtual money is free. Try the live demo instantly without an account, then make a free account to save your portfolio and climb the leaderboard.
That's the entire idea. You get $100,000 in virtual money on real charts, so you're practicing the mechanics and speed of intraday trading without a single real dollar at risk.
Yes. Prices are real-time from Tiingo, not 15-minute delayed. The chart refreshes about once a minute rather than streaming every tick, so it's great for drilling order entry, sizing, and stops, but it isn't a tick-by-tick scalping terminal. It's about the mechanics.
No tool can promise that, and this one won't either. Day trading is hard and many people lose money at it. The simulator is for practice and building familiarity with the mechanics, nothing more. It's not investment advice.
No, not to try it. Jump straight into the live demo and start placing practice trades right away. Making a free account is what saves your portfolio so you can climb the leaderboard.
