A demo account is a simulated trading account with fake money and live market prices. Every broker offers one free, and every beginner should use one before risking anything.
What demo is genuinely good for
- Platform mechanics. Placing orders, setting stops, closing positions, reading the account panel. Getting this wrong with real money is an avoidable way to lose it.
- Instrument behaviour. Watching how your chosen market moves across a session, where it goes quiet, how it reacts to the open.
- Testing a process. Running a set of rules across enough trades to see whether the idea has any merit before funding it.
- Recovering from mistakes. You will misplace a decimal, click buy instead of sell, and forget a stop. Better that this happens on demo.
Where demo misleads
This is the part that gets skipped.
- Fills are too good. Demo servers often fill limit orders the real market would not have reached, and apply little or no slippage. A method that looks fine on demo can be unprofitable live purely on execution.
- Spreads may not match. Some demo feeds do not reproduce the spread widening that occurs around news and at session changes.
- No emotional load. Losing simulated money produces nothing. Losing real money, particularly money you needed, changes how you behave in ways you cannot predict in advance. Traders who are disciplined on demo routinely are not once funded.
- Position sizing is unrealistic. People trade demo accounts far larger than the account they will actually fund, which makes the results irrelevant to their real situation.
How to use demo properly
- Set the demo balance to the amount you will actually trade with, not 100,000 dollars
- Use the same instrument, same hours and same position sizes you intend to use live
- Record every trade, including the reasoning, as you would live
- Run enough trades for the sample to mean something, which is more than ten
- Move on when the mechanics are automatic and the process is defined, rather than when you have had a good week
After demo
The usual recommendation is to go live at the smallest size the broker permits, even if the amounts are trivially small. The reason has nothing to do with the money. Real money reintroduces the emotional component demo cannot simulate, at a size where the lesson is cheap.
Prop firm evaluations sit somewhere in between. The capital is not yours, so the loss is limited to the fee, while the rules and the pressure are real. They do not replace demo, and starting one before the mechanics are automatic means paying to learn things that were available free.
