Tracker is for symbol price/IV history, not positions. The "Save to Tracker" button now adds the symbol to a watchlist (localStorage); the Tracker page shows the watchlist as clickable chips. New "Enter Position" button on the Strategy page posts the active legs to /api/orders, then opens the new Positions page. New Positions page (positions.html): lists entered positions with live mid value, round-trip commission, gross & net P/L (Net = Gross − round- trip commission), per-symbol filter, summary totals, close/reopen and remove actions. New Settings page (settings.html) configures the commission used on Positions. Defaults to Interactive Brokers Fixed / IBKR Lite: $0.65 per contract, $1.00 minimum per order (https://www.interactivebrokers.com/en/pricing/commissions-options.php). Per-leg vs per-order toggle for complex orders. Sidebar nav now: Dashboard · Options Chain · Vol Surface · Strategy P/L · Positions · Tracker · Settings.
