About Personal Execution Quality Scorecard (NBBO)

Brokers publish execution quality data — but only as firm-wide averages. There's no way to check whether your specific fill was actually good, using their aggregate quarterly stats. This extension lets you log your own trade fills — symbol, side, price, and the NBBO at the time — and get an instant, personal verdict: price improvement in real dollars, effective spread, and a letter grade (A–F) based on how your fill compared to the quoted market. Features: Real-time calculation as you type — no submit button needed Personal letter grade (A–F) per trade, based on your actual execution Trade log with full history Portfolio dashboard: total $ impact, % of trades with improvement, overall grade Pro: breakdowns by order type, symbol, and broker; execution quality trend over time; CSV import/export Nothing is sent to any server except an optional license check. All your trade data stays local to your browser.
