A profitable simulator result can feel like proof that a strategy works. It may be useful evidence, but it is not enough on its own. A short sample can benefit from one market regime, one lucky entry, or assumptions that would be difficult to reproduce.
Before increasing a practice position, review how the result was produced. The five questions below are designed to turn a simulator balance into a clearer learning record.
1. Did the trade follow a rule written before entry?
Start with the decision, not the outcome. Read the original note and compare it with the order. Did you enter because the planned condition appeared, or did you edit the explanation after price moved? If you cannot tell, mark the trade as unclear rather than calling it a strategy win.
A rule does not need to be complicated. It can define a market, timeframe, entry condition, invalidation, and review time. The important part is that the same rule can be evaluated on the next trade.
2. Was the size consistent with the plan?
Compare the position with the account balance and the amount you intended to risk. A larger position can make a correct market read look better and a small mistake look worse. If size changed because you felt confident, record that separately from the setup quality.
The position size calculator can help you test a consistent risk assumption. It does not choose a size for you, and a simulated account does not make an oversized position harmless as a learning experiment.
3. Did costs and execution assumptions match the exercise?
Review fees, spread, order type, and any leverage assumption. A market order and a limit order can produce different simulated fills. A result that ignores small costs may look different after many repeated trades. Use the paper-trade guide as a checklist for your assumptions.
Do not make the assumptions more favourable after seeing the result. If the simulator cannot model a cost, write that limitation in the journal instead of hiding it.
4. What happened when the trade was uncomfortable?
The most useful review often begins before the exit. Did you move the stop, close early, add to the position, or stare at the price until you changed the plan? These actions show how the process behaves under pressure. A strategy that looks clear in a spreadsheet may need a different rule when the market moves quickly.
Record the action without labelling yourself as disciplined or undisciplined. The next practice session can test a concrete change, such as a time-based review or a written no-add rule.
5. What would you need to see before changing size?
End with a threshold that is about evidence, not excitement. You might require more logged trades, a review across different market conditions, or consistent execution of the same rules. There is no universal number of trades that proves a method. The point is to avoid changing size after a small run of results.
A good review can end with no size change. That is still a decision. It means the current sample is being used to improve the process rather than to justify more exposure.
Make the review repeatable
Use the same five questions after every group of practice trades. Save the original plan, the actual order history, and a short note about what changed. Over time, you will have more than a balance curve. You will have evidence about entries, exits, costs, sizing, and behaviour.
