Practice Portfolio

What the practice portfolio tracks

The portfolio page shows open positions with entry prices, current practice prices and unrealised profit or loss, plus this browser's history of closed trades. Guest records live in local storage. Signed-in cash and open positions can sync when the service is available; clearing browser data does not delete an account copy already stored on the server.

Beyond raw P&L, the page calculates the metrics that actually describe a process rather than an outcome: fee-inclusive closed-result win rate, average win versus average loss, current open-position return dispersion, and practice maximum drawdown. The chart can include generated history; it is not a verified sequence of account observations.

How to read your own numbers honestly

• Compare win rate, average realized win, average realized loss and costs together. A high win rate alone does not establish a positive result.
• Maximum drawdown describes a selected peak-to-trough decline. It does not measure every risk or predict your response to a real loss.
• A short run is an observation, not proof of a repeatable advantage. Selection, dependence, costs and changing conditions matter; no fixed trade count establishes an edge.
• If one position drives most of the return, you learned about that position, not about your method.

Why results here do not transfer one-to-one

The simulator applies a 0.1% practice transaction fee, rather than a real broker fee schedule. It does not model financing costs, taxes or actual market execution. Review practice results alongside these limits; they do not predict real-money results.

The metrics explained in plain language

• Unrealised P&L: what an open position is worth right now versus what you paid. It is not money until you close.
• Realised P&L: the result of trades you have actually closed. This is the number that measures decisions you finished making.
• Open positions in profit: the share of current open positions showing positive unrealised P&L. This is not a closed-trade win rate.
• Open-position P&L dispersion: the spread of current position returns around their average. This is a snapshot, not a Sharpe ratio or time-series volatility measure.
• Practice maximum drawdown: the largest fall from a peak in locally stored snapshots, which can include generated hourly backfill. It is not an observed market record or proof that a strategy is survivable.

Reviewing the portfolio weekly

Choose a repeatable review interval for virtual results and compare the information recorded before each order with what became known later. A loss alone cannot establish whether the original reasoning was sound.

Compare the largest virtual gain with its position size, price change, quotation source and costs. A large one-off outcome does not by itself establish skill or predict a similar future result.
