QL Mirror
Every platform grades markets. Nobody will honestly grade you. Mirror points the same 51-lab diagnostic battery QuantLogix runs on its own signal record at your trade history: is your edge skill or luck, how many trades until it's statistically real, do you tilt after losses, does your sizing add money or burn it, and does your confidence actually mean anything?
🔒 Stateless — your trades are graded in memory and never stored
Import your record CSV paste, CSV/PDF file, Plaid brokerage, or paper portfolio
Waiting for data
CSV/TSV needs one of: a return column (return_pct / ret / pnl% / gain-loss %), an entry_price + exit_price pair (optionally side long/short), or a cost_basis + market_value pair from a positions statement. Optional: date, ticker, sector, conviction (any numeric scale — enables the calibration and sizing labs). PDF brokerage statements are parsed in your browser — the extracted rows land in the box above for review before anything is sent. Plaid uses your already-linked brokerage; paper uses your QuantLogix paper wallet. Minimum 10 trades. Nothing you import is stored.
Fix First
The Five-Lab Verdict same formulas the Alpha Engine grades itself with
QL Mirror is diagnostic research, not investment advice or a performance certification. Verdicts are statistical reads on the record you provide; garbage in, garbage out. Nothing you import is stored, logged, or used for any other purpose. Formulas: Wilson interval & proportion z-test (significance lab), Probabilistic Sharpe & Minimum Track Record Length (robustness lab), gross-matched sizing replay (portfolio replay lab), Wald–Wolfowitz runs test.
