This permanently deletes your account, portfolio, trade history, and watchlist. This cannot be undone.
Upload a CSV with these columns: date, symbol, side, qty, price.
Date must be YYYY-MM-DD, side must be BUY or SELL.
These get merged into your existing portfolio (average cost is recalculated), and your
cash balance is left untouched since these are historical trades, not new ones.
