# Trading Overview

> Place, protect, and manage orders on any connected account — one order path, idempotent by design.

Trading is how orders reach the venue on trdrs: market, limit, stop, and stop-limit entries,
protective exits that travel with them, and position actions for the moments that matter. Every
request that can create or move money carries [an idempotency
key](/partner-platform/overview/idempotency), so a retry is always safe.

## What you can build

* **Place orders with exits attached** — the stop and target ride along atomically, as one unit or not at all.
* **Set and move protection after entry** — each level is three-state: a number sets it, null removes it, omitting it leaves the resting leg alone.
* **Manage what's resting** — replace an order's price, cancel one, or cancel everything working. A replace reports its own `outcome`, and only `amended` and `replaced` are successes.
* **Act on positions** — flatten one instrument, flatten the account, reverse a position, close part of one. Each cancels something different first.
* **Apply saved exit plans** — preview a plan against the account, then place by reference, never by retyped levels.
* **Configure leverage where the venue has it** — read and set leverage and margin mode per instrument, and price an order's margin before sending it.
* **Respect the risk gate** — a locked account answers `423` to every order; the controls that lock it are readable and settable.

## Core objects

An order, a position, its exits (the stop and target), an exit plan, and the risk controls. Each
appears in [Trading](/api-reference/trading/place-an-order) and
[Account](/api-reference/account/list-accounts) in the reference.
