Paper trading is the cheapest tuition available in investing. You get to make the mistakes that would otherwise cost you real money, and the only thing you lose is time.
Before the list, one thing worth stating plainly: almost every “best simulator” article you’ll find is monetized by referral fees from the platforms it ranks. Some are transparent about it, most aren’t. So each entry below notes who owns the product and how it makes money, because that shapes the experience more than any feature list does.
Investopedia Simulator
Free, no brokerage account required, $100,000 in virtual cash. You need an Investopedia login and nothing else.
This is the one most people are sent to first, and it’s the gentlest introduction of the five. The interface is uncluttered, you can create or join games with custom rules and starting balances, and there’s a leaderboard if competition motivates you. Stocks, options, and crypto are supported.
The tradeoff is that quotes are delayed, refreshing every 15 minutes rather than streaming live. For someone learning what a limit order is, that’s irrelevant. For anyone practicing anything time-sensitive, it’s disqualifying, and you’d be building habits around prices that aren’t there anymore. There’s also no watchlist, the mobile experience is rough, and coverage skews heavily to US-listed stocks, so European names are largely missing.
How it makes money: Investopedia is owned by Dotdash Meredith and doesn’t operate a brokerage. It monetizes through advertising and affiliate commissions on broker recommendations, so the simulator is a top-of-funnel product feeding readers toward those placements. Not a direct pipeline to one firm, but the “best broker” content you’ll be shown afterward is paid placement.
Wall Street Survivor
Free, $100,000 virtual portfolio, real-time data on stocks and ETFs, options included. Email and password to sign up, no Social Security number, no download.
The simulator itself runs on Stock-Trak, which is the same engine behind a lot of classroom and corporate trading competitions, so the mechanics are solid. What distinguishes Wall Street Survivor is the course library wrapped around it. You can read a short lesson on how orders work and then immediately place one, which is a better learning loop than reading and practicing in separate places. Leagues let you compete against friends with your own rules.
How it makes money: this one deserves a closer look. Wall Street Survivor runs an extensive “best stock newsletters” ranking operation, publishing quarterly performance analyses of paid subscription services and linking to them. Those links are affiliate links. So the funnel here doesn’t end at a brokerage, it ends at a $200 to $500 a year stock picking subscription. The simulator is genuinely free and genuinely useful, and the surrounding content is built to sell you newsletters whose claimed outperformance you have no independent way to verify. Use the simulator, treat the rankings as advertising.
MarketWatch Virtual Stock Exchange
Free, browser-based, registration required, minimum age 16.
VSE is the most flexible of the group for structured competition. You set the starting budget yourself rather than accepting a default, and you can enable margin, short selling, limit and stop-loss orders, and partial shares. Custom watchlists sit alongside your holdings. You can create a private game with your own symbol list and password, which is why teachers use it constantly. MarketWatch publishes classroom documents for exactly that purpose.
Pricing is real-time rather than delayed, which puts it ahead of Investopedia for anyone who cares about execution timing. The interface is plain but it works across screen sizes.
How it makes money: MarketWatch is owned by Dow Jones, part of News Corp, alongside The Wall Street Journal. There’s no brokerage attached. The product you’re being moved toward is registration and eventually a news subscription. That’s a milder conflict than the alternatives, and it’s the reason VSE is the cleanest recommendation here for pure practice.
thinkorswim paperMoney
Free, $100,000 virtual balance, real-time data, and the deepest toolset on this list. Stocks, options, futures, and forex.
A correction on the name, since older articles still get it wrong: this is a Charles Schwab product now. Schwab completed its acquisition of TD Ameritrade and retired that brand, and thinkorswim is Schwab’s flagship trading platform, still receiving quarterly feature releases.
paperMoney is not a simplified game. It’s the actual professional platform with simulated money behind it, including the Analyze tab for modeling options positions, scanning through Stock Hacker, and thinkScript for custom studies. If you intend to trade options seriously, nothing else here is close. The cost is a real learning curve, and beginners often find it overwhelming in the first week.
How it makes money: this is the most direct funnel on the list, and Schwab doesn’t pretend otherwise. A Schwab brokerage account is required to log into thinkorswim and use paperMoney. There is a workaround worth knowing: Schwab offers a 30-day Guest Pass that gives you paperMoney credentials with no account, which is enough time to decide whether the platform suits you. After 30 days, you open an account or you leave.
Webull paper trading
Free, real-time data, stocks, ETFs, and options, with over 60 technical indicators and charting that mirrors the live platform. Available on web, desktop, and mobile, with a resettable virtual balance.
Webull’s charting is genuinely good and the mobile app is the best of this group, which matters if you’ll actually practice in spare moments rather than at a desk. Trades execute against live market data.
Two limitations to know before you rely on it. The paper account does not support stop-loss or take-profit orders, so you’ll be managing exits manually. That’s a real gap, because risk management is the single most useful thing a beginner should be practicing, and the simulator can’t teach you the habit it most needs to. Alerts require the mobile app and don’t work in the desktop simulator.
How it makes money: Webull is a brokerage. The simulator exists to get you familiar with the interface so that funding a live account feels like a natural next step, and it works. That isn’t sinister, it’s just worth naming.
Which one to pick
If you’re learning what a stock is and how an order works, MarketWatch VSE or Investopedia. VSE if you want real-time prices and competition with friends, Investopedia if you want the simplest possible starting point and don’t mind delayed quotes.
If you want lessons and practice in the same place, Wall Street Survivor, with the newsletter marketing filtered out.
If you’re heading toward options or futures, thinkorswim paperMoney via the Guest Pass, and give yourself a month before judging it.
If you want something good on a phone, Webull, keeping in mind that you’ll have to practice stop-losses somewhere else.
What paper trading can’t teach you
Every simulator shares the same blind spot, and it’s the one that matters most.
Simulated fills are optimistic. Your order executes at the quoted price with no slippage and no competition for liquidity, which is not how thin stocks or fast markets behave. Options fills are the worst offender, because a simulator will happily fill you at the mid-price on a spread that would take real negotiation to get done.
The virtual balance distorts your behavior. Handed $100,000 when you plan to invest $2,000, you’ll take positions you’d never take with your own money, and the lessons won’t transfer. Set your starting balance to what you’ll actually invest, on the platforms that let you.
And the emotional half is entirely absent. Watching a fake portfolio drop 20% is a mild annoyance. Watching your actual savings do the same thing produces decisions that look nothing like the ones you made in practice. Paper trading builds mechanical competence with orders, platforms, and position sizing. It does not build the temperament, and a strong simulated track record is weak evidence that you’ll behave the same way with money on the line.
Use one for a month to learn the mechanics. Then think carefully about whether frequent trading is the strategy you want at all, because the research on retail active trading is consistently unkind, and none of the companies above have any reason to tell you that.
