What is paper trading, and what can it not teach you?
A paper trading account, also called a trading simulator or demo account, gives you a virtual balance and fills your orders against market prices. You use the same chart, order ticket and order types you would use with a broker. That makes it good for learning the mechanics: how a limit order differs from a stop, how to size a position, and whether you can follow your own rules for weeks in a row.
It also has blind spots. Simulated fills are usually cleaner than real ones: the order fills at the price you wanted, with no queue, no partial fill and little or no slippage. And the money is not real, so the fear that makes traders move stops, skip signals or exit early never shows up. Treat paper results as a best case: a plan that loses on paper with costs turned on is unlikely to do better live.
- Paper trading
- Practice trading with a virtual balance: orders are simulated against market prices, and no real money or shares change hands.
- Fill
- The execution of an order: the price and number of shares you actually got, which can differ from the price on the screen.
- Slippage
- The difference between the price you expected and the price your order filled at, usually larger in fast or thinly traded markets.
How do you open Paper Trading on TradingView?
At the time of writing, TradingView’s help pages describe Paper Trading as available to all users. The interface changes from time to time, so the labels on your screen may differ slightly:
- Open a chart (Supercharts) of the symbol you want to practise on.
- Click Trade in the top-right corner, or open the trading panel under the chart, choose Paper Trading from the list of brokers and click Connect.
- Open the account settings. Commissions are off by default; turn them on and enter what your real broker charges, as a fixed amount, a percentage or, for futures and options, an amount per contract.
- Place orders from the order ticket (market, limit or stop, with the size and the stop and target levels), from the depth of market panel, or by dragging orders on the chart.
- You can keep several paper accounts and switch between them. Resetting an account deletes its history, active orders and open positions, so export your trades first.
- If the virtual balance is far larger than the money you will really trade, size every position as if the account were your real size.
Paper vs real fills: why paper results look better
Hypothetical: your plan buys 200 shares of XYZ at $50.00, with a stop at $49.40 and a target at $51.20. The risk is $0.60 a share, so 1R is $120, and the target is 2R away. On paper, the order fills at $50.00 and the stop at exactly $49.40: a loss is −$120, or −1R, and a win is +$240, or +2R.
Live, a market buy pays the ask, $50.02, plus a cent of slippage: $50.03. In a fast drop, the stop fills at $49.33, 7 cents below the stop price. A loss is now ($50.03 − $49.33) × 200 = $140, or −1.17R, and a win at the $51.20 limit is $234, or +1.95R. If 4 trades in 10 win, the paper expectancy is 0.4 × 2 − 0.6 × 1 = +0.20R per trade; with the real fills it is 0.4 × 1.95 − 0.6 × 1.17 = +0.08R, before commissions. Same trades, less than half the edge. The trading expectancy lesson explains the formula, and the bid-ask spread lesson where those cents go.
You cannot make paper fills realistic, but you can make them honest: turn commissions on, log entries at the ask and exits at the bid, and add a few cents of slippage to every stop in your journal.
How to combine paper trading with Bar Replay
Paper trading runs at the speed of the market: a swing setup may appear twice a month, so 30 paper trades can take months. Bar Replay compresses that time: it hides the bars after a date and plays the chart forward, so you can make dozens of decisions in an evening without hindsight. The two answer different questions, so use them as steps of one ladder, drawn at the top of this page:
- Backtest: do the rules show an edge on past data at all? See how to backtest a trading strategy, and beware of rules tuned to the past, the trap described in backtest overfitting.
- Bar Replay: can you apply the rules by eye, bar by bar, without hindsight?
- Paper trading: can you follow them at live speed, with real-time orders, during the hours you actually trade?
- Small real size: do they survive real fills, costs and your nerves?
What should you measure while paper trading?
Log every paper trade in a trading journal the way you will log real ones: setup, entry, stop, target, size, exit, the result in R after costs, and whether you followed the plan, in a tab separate from replay and live trades. Then grade the process, not the profit. The scorecard below sums up 30 hypothetical paper trades of one setup:
- Plan followed: 28 of 30 trades. One stop was moved (the −1.3R loss) and one trade was closed early (the +0.4R win).
- Wins: 11 of 30 (37%), averaging +2.00R. Losses average −1.03R, slightly worse than −1R because of slippage.
- Expectancy: +2.4R in total, or +0.08R per trade.
- Largest loss −1.3R; longest losing run, 5 trades in a row.
When should you switch from paper trading to real money?
Do not read much into the +0.08R above. With 30 trades, the standard error of that average is about 0.28R, so the true figure could easily be below zero. What 30 trades do show is whether you can execute: stops placed before entry, correct sizes, rules followed. No paper profit proves you are ready; move up when the process is in place. Reasonable checks before your first real trade:
- At least 30 logged paper trades of one setup, and more for setups with small targets.
- The plan followed in at least 9 trades out of 10, with every stop placed before entry.
- Commissions on, and fills logged at the ask or the bid, plus slippage on stops.
- No single loss much larger than 1R: for example, nothing beyond −1.5R.
- An expectancy after costs that is not negative, keeping the small-sample caution in mind.
- A plan you can write in a few lines, as in a trading plan.
How to start with real money: small size, same journal
Start small: a quarter of your planned size, or a risk of 0.25% to 0.5% of the account per trade, for the next 20 to 30 trades. Use the position size calculator so a stop-out costs exactly what you planned. Then compare those live trades with your paper ones. If losses grow past 1R or rules start slipping, the difference is fear or fills, and it is far cheaper to find that out at small size. Most traders who skip this step learn the same lesson with full size, one of the patterns in why most traders lose money.
A real account also brings rules a simulator ignores, such as your broker’s day-trading margin rules for a US margin account: the old pattern day trader rule while brokers phase it out, or the new intraday margin standard that replaces it, explained in the PDT change.
Are demo accounts on binary options and CFD sites the same thing?
No. Search for a demo trading account and many results are offshore platforms selling binary options or CFDs, with a generous demo balance that is easy to grow. A demo on a platform that sets its own prices tells you little about a real market, and it is often the first step toward a deposit.
A joint investor alert from the US Commodity Futures Trading Commission (CFTC) and the SEC on binary options describes complaints about internet platforms that refused to credit customer accounts or return money, collected personal documents for unclear uses, and manipulated trading software, for example by extending a countdown until a winning trade became a loser. Before you deposit anywhere, check that the firm is licensed: through FINRA BrokerCheck or the NFA’s BASIC database in the US, or with your own regulator, such as the Capital Market Authority in Saudi Arabia. A paper account that takes no deposit is the safer place to practise.
