Calculation limitations
Explains where verified calculations still have uncertainty and how PnL Plus labels that uncertainty.
What it is. Verification does not mean every missing market tick or corporate-action detail is known. Some account histories contain gaps, reconstructed points or broker data that needs interpretation.
Why it matters. Limitations keep a clean-looking chart from overstating precision. A reconstructed MT drawdown can miss an intra-candle low; joined investment histories can make volatility and Sharpe indicative around the transition; rare corporate actions or FX gaps can leave a residual reconciliation difference.
How it works here. Unknown gaps stay unknown. MT4/MT5 reconstruction uses 5-minute candles and does not model every intra-candle extreme or triple-swap nuance. MT5 netting support remains limited where executions cannot be mapped into the same trade model. Exante/IBKR pre-monitoring curves are reconstructed from investment-account operations until measured NAV starts; accounts without convergence do not enter the public rating. PnL Plus verifies broker-sourced records and documented calculations, but it does not audit the broker, predict future returns or give investment advice.
