Returns per-symbol index values. When Greek indexes (Delta, Gamma, Theta, Vega, Rho) are requested, they are normalized: theta is the per-day value (one day's time decay), vega is the price change per 1% change in implied volatility, and rho is the price change per 1% change in the risk-free interest rate.

Cancel an open order by order_id. Returns plain text "order cancelled" on success; errors if the order is already filled or cancelled.

Call it first without execute, show the returned preview to the user, and only call it again with execute="<confirmation_code>" after the user has explicitly confirmed that exact order. The code is derived from the order itself, so it applies only to that exact order. Never quote it back on your own initiative, and never in the same turn the user first asks. The dry run also echoes the order being targeted so the user can verify it is the right one.

Estimate maximum buy/sell quantity for a symbol. Only symbol is required; side (case-insensitive Buy/Sell) defaults to Buy, order_type (case-insensitive) defaults to LO, and price is optional.

Cancel (terminate) a grid order by order_id. TWO-STEP CONFIRMATION IS MANDATORY: this tool is a DRY RUN unless you pass the confirmation_code its own dry run returned. Call it first without execute, show the returned preview to the user, and only call it again with execute="<confirmation_code>" after the user has explicitly confirmed it. The code is derived from the order itself, so it applies only to that exact request. Never quote it back on your own initiative.

TWO-STEP CONFIRMATION IS MANDATORY: this tool is a DRY RUN unless you pass the confirmation_code its own dry run returned. Call it first without execute, show the returned preview to the user, and only call it again with execute="<confirmation_code>" after the user has explicitly confirmed it.

Restart (resume) a suspended grid order by order_id. TWO-STEP CONFIRMATION IS MANDATORY: this tool is a DRY RUN unless you pass the confirmation_code its own dry run returned. Call it first without execute, show the returned preview to the user, and only call it again with execute="<confirmation_code>" after the user has explicitly confirmed it. The code is derived from the order itself, so it applies only to that exact request. Never quote it back on your own initiative. A restarted grid resumes placing orders on its own.

Submit a grid trading order. DRY RUN unless execute is the confirmation_code from its own dry run: call once without execute, show the preview, then re-call quoting the code only after the user confirms.

Suspend (pause) a running grid order by order_id. Resume with grid_restart. TWO-STEP CONFIRMATION IS MANDATORY: this tool is a DRY RUN unless you pass the confirmation_code its own dry run returned. Call it first without execute, show the returned preview to the user, and only call it again with execute="<confirmation_code>" after the user has explicitly confirmed it. The code is derived from the order itself, so it applies only to that exact request. Never quote it back on your own initiative.

Attached take-profit/stop-loss legs are changed here too: attached_order_type with the new attached_profit_taker_price / attached_stop_loss_price adds or reprices a leg, attached_profit_taker_id / attached_stop_loss_id target an existing leg, and attached_cancel_all=true removes every leg while leaving the order in place.

Pass symbol to filter by security, or order_id for one order. To fetch an attached leg by its own ID, pass that ID as order_id together with is_attached=true — the leg itself comes back as the order entry. is_attached does nothing without order_id, and neither has any effect for US accounts, which are served by the US order endpoint. US accounts only: us_action (Buy/Sell), us_page, us_limit filter/paginate via a separate US order endpoint.
