Every MT4/MT5 account linked to this API key: id, nickname, platform, broker server, login and connection status (connected / connecting / disconnected / error). Call this first: the other tools take its account_id values. Set include_balances to also read each account's live balance, equity and floating profit from its terminal, plus totals per currency; that reads at most 50 accounts, and one that cannot be read gets a balance_error instead of failing the call. For one account's margin, leverage and settings, use get_account instead.
