The Account Summary tool gives you a real-time snapshot of everything happening with your account. This is where you'll find your consolidated gain/loss (G/L), balance, and order information for an account. It displays how much your account is up or down for the day or since purchase on open positions and positions you closed out that day. The balance section highlights buying power balances for quick reference as a seamless part of your trade flow. You'll also have access to information on the number of open orders, open positions, trades executed today, and price improved orders.
For definition on balances shown on the Account Summary tool, go to Balances.
