Overview

Before placing orders, review the trader integration playbook in getting-started/trader-questions.md: tradable symbol, correct balance type, execution mode, and status tracking path.

Order types

Type	Side	Required fields
Market buy	Buy	notional
Market sell	Sell	quantity
Limit	Buy or Sell	quantity, price, timeInForce

All orders require stockAddress (from symbols list) and deadline (Unix seconds, ≤ 4294967295).

Market orders (buy/sell, incl. deferred market sell) are accepted only during the regular US trading session. Outside it (pre-market, after-hours, overnight, closed) they are rejected up front — use limit orders. Limit orders are unaffected. See place-and-cancel-orders.md.

Use strings for quantity, notional, and price to avoid JS precision loss.

Deferred sell (selling a stock before holding it, creating a repayable debt) is placed through these same order endpoints with deferred: true + side: Sell (whitelist-gated). See deferred-sell.md.

Execution modes

Mode	Place order	Cancel limit	Record tx
Self-submit	POST /orders/calldata	DELETE /orders/{orderId}/calldata	POST /orders/tx
One Click	POST /orders/send	DELETE /orders/{orderId}/send	Auto-recorded

One Click requires enabled delegation — see one-click-delegated.md and guides/one-click-flow.md.

Typical flow

1. Check portfolio for buying power and holdings.

2. Get quote from market if needed.

3. Build or send order — place-and-cancel-orders.md.

4. Track status — order-status-and-history.md.

Self-submit sequence: see guides/self-submit-on-chain.md.
