How to review paper-trading results realistically
Paper trading provides a place to practice a process. Its results are only as useful as the assumptions you record and the questions you ask afterward.
A changing quote is not an executed trade
Market-connected practice can show how a simulated position changes as quotes refresh. That is different from proving an order would execute at the displayed value. The last trade may be old, the bid and ask may be far apart, and a midpoint may not be an available fill.
Write down whether your entry and exit values came from a bid, ask, midpoint, last trade or a manual assumption. Record the timestamp. If the quote is missing or stale, mark the result as incomplete instead of silently replacing it with a favorable value. See the OCC/OIC trade-entry and execution FAQ for execution context.
Make costs and uncertainty visible
Keep fees and execution assumptions alongside gross P/L. For a simple illustration, an assumed $50 gross gain with $4 of total fees is $46 before any additional execution difference. If the combined entry and exit outcome is $10 worse than assumed, the result becomes $36. This arithmetic is an illustration, not a forecast or a typical return.
You do not need to guess a universally correct slippage number. Record what you assumed, then ask whether a less favorable fill would materially change your interpretation. Compare results using consistent assumptions rather than changing them from trade to trade.
Review capital and obligations, not just the payoff chart
Check that the practice account could support the position under its stated collateral and buying-power rules. A chart at expiration does not show every event that can occur before expiration. Multiple expirations, changes in volatility and management actions can make a position's current value differ from its final payoff illustration.
A short American-style option can be assigned before expiration. Holding another option does not by itself prevent assignment of the short leg. Record how your practice handles exercise, assignment and settlement, and what the simulator omits. Review the OCC/OIC assignment FAQ; broker procedures and deadlines matter in live trading.
Use a repeatable end-of-week review
- Reconcile: Are all position changes, closes and costs recorded?
- Check inputs: Are prices current enough for the conclusion being drawn?
- Separate: Which figures are realized, unrealized or assumption-based?
- Explain: Did the position change for the reason originally expected?
- Compare: What happens under less favorable execution assumptions?
- Learn: Choose one process question to investigate in the next practice session.
Keep the original notes. A clean history helps you see whether a change improved your process or simply benefited from a different market. A small sample of simulated wins cannot establish a reliable edge, and a simulator cannot reproduce every practical or emotional feature of risking money.
Bring the review into your workflow
TradeLog is free standalone software for journaling, notes, reports and market-connected simulated position review. Quotes refresh through supported application actions, and values and P/L update accordingly; this is not guaranteed streaming data or broker execution. Use the trade-journal checklist to keep assumptions visible.
