What it means
A demo may use indicative prices and simulated execution. A live order interacts with the broker’s actual execution arrangements and can experience rejection, partial fills or slippage. Even when prices look similar, emotional pressure changes behaviour. Demo profitability is therefore evidence that a process was followed in simulation, not proof of future live performance.
The most useful way to learn this topic is to connect the definition to an actual order ticket. A platform may use abbreviations, decimal formatting or account labels that differ from another broker. Open the instrument specification and confirm how that provider defines contract size, minimum volume, trading hours, margin and charges. Do not assume that a familiar label creates identical conditions across accounts.
Keep the measurement separate from the decision. A term can describe what happened without proving that a trade was sensible. Good decisions also require an affordable risk limit, a reason for entering, a clear exit plan and an understanding of what could invalidate the idea. This distinction is especially important in leveraged products, where a small market move can produce a large change in account equity.
Worked example
A strategy that places large orders during news may fill instantly on demo but receive worse prices live. A trader may also hold a demo loss calmly, then close an identical live position early because real money is at stake. Moving to live should mean reducing size and testing operations, not immediately copying the demo balance scale.
This example is deliberately simplified. A live result can also include spread, commission, financing, currency conversion and slippage. Prices can gap between available quotes, and a broker can change margin requirements when risk rises. Use the example to understand the calculation, then repeat it using the live contract specification and fee schedule for the precise account.
How to use this knowledge
| Key point | What to do |
|---|---|
| Demo is best for platform and process learning | Check the broker specification instead of relying on a general assumption. |
| Live execution can differ | Calculate the effect using the intended position size and account currency. |
| Psychology changes when money is real | Compare normal conditions with a fast or illiquid market scenario. |
| Demo results are not investment performance | Write the rule in the trade plan so it can be followed consistently. |
| Small live tests can reveal operational issues | Verify the latest wording before funding or placing an order. |
Numbers should be compared on the same basis. A one-way commission is not comparable with a round-turn commission, a minimum spread is not the same as an average spread, and maximum leverage is not the same as the amount a careful trader must use. Record the unit, time period and account type next to every number.
A demo account is useful for checking buttons and calculations, but it cannot guarantee the same live execution. When moving to real funds, use a small position and test the complete process, including order modification, closure, statement retrieval and withdrawal. Keep screenshots or statements when an execution result needs investigation.
South African context
South African readers should verify which company will legally hold the account. A global broker brand may place clients with different subsidiaries. Search the exact company name and licence number on the official regulator register, then compare those details with the client agreement. An FSCA reference on a website should not be accepted without an independent check.
Also check whether the account is funded and reported in rand or another currency. Conversion can affect deposits, withdrawals, charges and the value of profit or loss. SAST stays at UTC+2, while overseas financial centres can change their clocks seasonally. Economic-calendar and market-session times should therefore be converted carefully.
Tax depends on facts such as the nature, intention and frequency of activity. A general guide cannot determine an individual tax outcome. Keep complete broker statements and consult SARS guidance or a qualified tax professional where needed. Regulation, tax treatment and product availability can change, so date every verification.
Common mistakes to avoid
Check this
Choosing unrealistic demo capital. Slow down, confirm the relevant number or clause, and record the evidence before acting.
Check this
Ignoring commission and swap settings. Slow down, confirm the relevant number or clause, and record the evidence before acting.
Check this
Moving to maximum live size after a short test. Slow down, confirm the relevant number or clause, and record the evidence before acting.
Check this
Treating demo fills as guaranteed live fills. Slow down, confirm the relevant number or clause, and record the evidence before acting.
A second common problem is false precision. A calculator can produce an exact-looking answer from assumptions that are already outdated. Live spreads, conversion rates, margin and swap can change. Treat the result as an estimate until the order ticket and current broker document confirm it.
Practical checklist
- Match demo account type to the intended live account.
- Record spreads and commissions.
- Practise stops and pending orders.
- Test deposits and a small withdrawal live.
- Increase size only under a written rule.
Complete these checks before using real money. If a broker document is unclear, ask support a specific written question and save the reply. If the answer conflicts with the legal terms, rely on the contract and regulator information, or do not proceed until the discrepancy is resolved.
Questions answered
No. It helps explain mechanics or risk, but it cannot predict market direction or guarantee execution. A correct calculation can still be followed by a losing trade.
Verify it in the current legal document, contract specification or live platform. Check whether it is a minimum, average, maximum or example and which entity and account it covers.
Repeat the worked example with a demo account, read the product terms, and define a cash risk limit. Learning the order process is more important than rushing to place a live trade.
