Report the risk limits this account trades under and how much room is left against each of them. These limits are enforced outside you and no tool changes them — check here before sizing an order rather than discovering a limit by being rejected.

Open positions with their signed notional in USD (negative is short), account value, and realised PnL so far today.

Top of book for a symbol: best bid, best ask, spread, and the nearest levels on each side.

Recent price history for a symbol as candles, oldest first: open, high, low, close and volume for each interval. The newest candle is usually still forming — lastCandleComplete says whether it has closed. averageRange is the mean high-to-low of the complete candles: how far price typically moves in one interval.

Place an order sized in USD notional. Every order is checked against the risk limits first; if it breaches one it is refused and nothing reaches the exchange. Omit price for a marketable order that crosses the spread. Both the order and your stated reason are written to a permanent log, including when the order is refused.

Protect an open position with a stop-loss held on the exchange: once the price reaches triggerPrice, the whole position is closed at market, whether or not you are running at the time. Replaces any stop already on that symbol. Below the market for a long, above it for a short. Logged with your reason, like an order.

Cancel a resting order by its exchange order id.

Flatten the whole position in one symbol with a reduce-only order that crosses the spread. This reduces risk, so it is permitted even when the daily loss limit has halted new trading.

Your own recent actions and the reasons you gave for them, most recent first, including any that the risk limits refused. Useful after a restart, when you no longer remember what you already did. Records with tool exchange_fill are what the exchange did without you: a stop-loss firing, or a resting order filling after you placed it.
