Key takeaways
• Paper trading means simulated trades with virtual cash, usually on live or near-live market prices.
• It teaches the mechanics well: order types, position sizing, reading a portfolio.
• It teaches the emotions badly, because losing fake money doesn't hurt. Plan for that gap.
• A simulator can also flatter you. Fills are cleaner than real life, and some costs are left out.
• Use it to test a written plan for at least a few weeks, not to chase a big fake balance.
What is paper trading?
Paper trading, also called simulated trading or virtual trading, is practice investing with pretend money. The name comes from the old habit of writing trades on paper to see how they would have turned out. Today an app or broker platform does it for you.
You choose a stock, decide how many shares to buy, and place the order. The platform "fills" it at a market price and tracks your gain or loss as prices move. Nothing is deducted from a bank account, because there isn't one behind it.
Platforms describe it in similar terms. TradingView says its paper trading uses simulated money with no deposits and is available to all users. Alpaca, a broker with an API, offers paper accounts that are free and can be opened with an email address.
How does paper trading work?
Every simulator follows the same loop:
1. You get virtual cash. The starting amount depends on the platform. Alpaca's documentation says a new paper account starts with a $100k balance by default. Other platforms choose their own amounts, so check yours.
2. You place an order. Market order, limit order or stop order, just as you would with real money.
3. The simulator fills it. It uses market prices to decide the fill. A real market has to find a seller for your shares. A simulator mostly just assumes one exists.
4. Your portfolio updates. You see open positions, cash left and profit or loss.
That is all there is to it. The skill you build is not picking winners. It is learning what each button does, and what your own behavior looks like when a position moves against you.
Why paper trade? What it is good for
• Learning the mechanics. Market versus limit orders, what a stop does, how a short sale works, how fast a position can move.
• Practicing position sizing. Decide how much of your account to risk on each trade and see how that plays out over twenty trades.
• Testing a plan. If you have a written set of rules, a few weeks of simulated trades show whether you can follow them.
• Learning a platform. Finding every setting before real money is involved prevents expensive mistakes.
• Building a routine. Reviewing every trade in a journal is a habit worth building early.
How to start paper trading in 5 steps
Step 1: Pick a simulator
Choose one with real market prices and an interface you will actually open. Brokers, charting platforms and learning apps all offer one. Our comparison of the main paper trading apps and their flaws explains how they differ.
Step 2: Set a realistic account size
This is the most common beginner mistake. If your real budget is $1,000, do not practice with $1,000,000. Many simulators let you change the starting balance, and you should set it to roughly what you would really invest. Otherwise your results mean nothing.
Step 3: Write your rules before your first trade
Write down, in a sentence each:
• What you are looking for before you buy (your reason)
• How much of the account you will risk on one trade
• Where you will exit if you are wrong (your stop)
• Where you will take profit, or when you will review the position
Step 4: Size every position with a formula
Here is a worked example with round numbers. Say your paper account is $10,000 and you decide to risk 1% per trade.
• Dollar risk = $10,000 × 1% = $100
• You buy at $50 with a stop at $48, so you risk $2 per share
• Shares = $100 ÷ $2 = 50 shares (a $2,500 position, 25% of the account)
If the stop is hit, you lose about $100, which is 1% of the account. That is the idea behind position sizing: you decide the loss before the trade, not after. You can try your own numbers with our position size calculator.
Step 5: Keep a journal and review it weekly
Record the date, ticker, entry, exit, size, reason and what you felt. After 20 to 30 trades, look for patterns. Do you cut winners early? Do you add to losers? The journal is where the learning is.
Is paper trading free?
Paper trading itself is usually free with brokers and charting platforms. Alpaca states its paper trading is free and available to all of its users. Terms differ elsewhere: some brokers require an account, some give a trial period, and some learning apps charge a subscription.
EquiTrek, the app behind this blog, is a subscription app, and we include it here as a disclosure, not an endorsement of one tool over another. Read the pricing on any platform before you rely on it.
The limits of paper trading (what the simulator does not tell you)
Paper trading is useful, but it is not a rehearsal of everything real trading will throw at you.
1. The money isn't real, so the emotions aren't either
When a fake position drops 15%, nothing happens in your stomach. When a real one does, you may feel the urge to sell immediately. This is the biggest gap, and it is covered in depth in Paper Trading vs. Real Trading: Why You Lose Money When You Go Live. Practice sizing positions you would actually be nervous about, and write down what you would do if the position fell 10%.
2. Fills are cleaner than reality
Alpaca's own documentation lists what its paper accounts do not account for, including market impact, price slippage due to latency, order queue position and regulatory fees. It also says a paper order can fill at a size much larger than the real available liquidity. In other words, your simulated results can be better than what a live account would deliver.
3. Some costs are missing
The same page says its paper accounts do not simulate dividends. Commissions, spreads and taxes may also be treated differently from one simulator to another. Always check what your platform includes before you trust its profit number.
4. Past simulated results prove very little
A hot streak with fake money in a rising market tells you almost nothing about how you would trade in a falling one. Schwab's thinkorswim paperMoney page carries a similar warning: virtual results do not guarantee success with real money.
Paper trading mistakes to avoid
• Using an unrealistic balance. A million dollars lets you take positions you could never afford, and the lessons won't transfer.
• Trading far too often. Without fees, it is easy to click all day. If this sounds familiar, read about revenge trading and how to stop it.
• Ignoring losses. If you would not feel comfortable showing a losing trade to someone, you are probably not learning from it.
• Never moving on. Paper trading is a bridge, not a destination.
How long should you paper trade?
There is no official number. A practical approach is to decide the finish line before you start, not the calendar. For example: "I will graduate when I have followed my written rules on 30 consecutive trades, my average loss is no larger than I planned, and I can explain each trade in my journal." Many beginners will find that takes several weeks, and some longer.
When are you ready to trade real money?
Consider going live when:
• You follow your own rules most of the time, not only when it is easy
• You understand every order type you plan to use
• You can explain, in advance, how much you could lose on each trade
• You are starting with an amount you can afford to lose
Start small. A small live account teaches you what a simulator can't, and the loss is limited. If you panic when a real position drops, our guide on how to stop panic selling can help you prepare.
Can you learn investing from paper trading alone?
Not entirely. Paper trading builds practical skill, but it works best alongside basic education: how companies make money, how compounding works, and how fees and taxes affect returns. If you are earlier in the journey, start with why most stock market courses fail beginners and our explainer on compound vs. simple interest.
The bottom line
Paper trading is a safe way to learn how markets work, test your rules and make your first mistakes for free. Treat it as practice for your process, not a scoreboard. Set a realistic balance, write your rules, size every position, keep a journal, and move to a small real account only when you can follow your plan.
If you want a simulator built around the behavior side of investing, you can try the EquiTrek app. It is our own product, so weigh that when comparing it with the other options.

Frequently Asked Questions
What is paper trading in simple words?
Paper trading is practicing buying and selling investments with pretend money, so you can learn without risking your savings.
Is paper trading the same as a demo account?
Mostly, yes. "Demo account," "simulator" and "paper trading account" are often used for the same thing: a practice account with virtual funds. The exact features vary by provider.
Can you make real money from paper trading?
No. Profits on a paper account are not real and cannot be withdrawn. Paper trading is for learning and testing only.
Does paper trading use real market prices?
Many platforms use live or slightly delayed market data, so prices move like the real market. The data source varies. For instance, Alpaca says paper-only accounts are limited to IEX market data.
How much virtual money should I start with?
Use roughly the amount you really plan to invest. Practicing with a balance far larger than your real one builds habits you can't use.
Is paper trading worth it for beginners?
Yes, for learning mechanics and testing a plan, as long as you understand its limits: no real emotions, cleaner fills, and some missing costs.
How is paper trading different from real trading?
The main differences are emotional pressure, order execution and costs. Our article on paper trading vs. real trading psychology covers the emotional side in detail.
