• tools/watchlist.py:38-49 (handler)

  The core handler function for the 'remove_from_watchlist' tool. It uppercases the symbol, loads the watchlist from JSON, removes the symbol if present, saves the updated list, and returns a confirmation message.

  def remove_from_watchlist(symbol: str) -> str:
      """
      Removes a symbol from the watchlist.
      """
      symbol = symbol.upper()
      watchlist = _load_watchlist()
      if symbol in watchlist:
          watchlist.remove(symbol)
          _save_watchlist(watchlist)
          logger.info(f"Removed {symbol} from watchlist")
          return f"Removed {symbol} from watchlist."
      return f"{symbol} was not in the watchlist."
