• get_portfolio_returns≈ 166 tokens

  Return RetireCrunch's historical portfolio return profiles for a currency. Each profile is a (return %, volatility %) pair derived from real index data — useful for grounding the assumptions in calculate_fire_target / project_wealth_plan in something defensible rather than guessing.

• get_rebalance_plan≈ 186 tokens

  Fetch the rebalancing trades the user decided on in the RetireCrunch Rebalancer, from the plan code they copied ("Send plan to my AI"). Codes work once, for 15 minutes. Returns the trades with IBKR contract ids where known. To act on them, create one IBKR order instruction per trade (create_order_instruction); the user reviews and submits each one inside IBKR. RetireCrunch never places orders.

• load_portfolio≈ 738 tokens

  Open the user's Interactive Brokers portfolio in the RetireCrunch Portfolio Rebalancer. First call the IBKR connector's get_account_positions, get_account_balances and get_account_summary, then pass their results here UNCHANGED (do not re-type or round numbers). Returns a private link that works once, for 15 minutes — give it to the user exactly as written. No login is needed because the link itself is the key: the positions are encrypted with a key that exists only in the link, and RetireCrunch's server holds just that encrypted copy, which it cannot read, for at most 15 minutes and deletes it when the link is opened. Tell the user this, and that anyone holding the link can open it once, so it should not be shared. RetireCrunch does not recommend instruments or allocations: the user sets their own targets on the page.

  • summary · object · optionnel
    The result of IBKR get_account_summary, unchanged (base currency + net liquidation, used to check the numbers add up).
