Core Concepts
A consolidated map of the trading entities and risk concepts used across the API.
Core trading entities
Accounts
Account settings, trading status, leverage, margin call, stop out, and account currency. Accounts matter because every trading and market-data workflow is scoped to account permissions.
Orders
Orders are trading instructions, including pending orders and SLTP objects. They matter because they represent client intent before or during execution.
Positions
Positions are open market exposure created by executed trading operations. They matter for PnL, margin, and close/modify workflows.
Deals
Deals are execution results and balance-affecting financial events. They matter for history, realized PnL, and reconciliation.
Market Data
Market Data includes candles, ticks, instrument updates, and trading-related events. It matters for pricing, charts, and strategy decisions.
Margin & Leverage
Margin and leverage determine how much exposure can be opened and maintained. They matter for no-money errors, margin calls, and stop out.
High Margin Requirements (HMR)
HMR periods may cap leverage for affected instruments. HMR matters because margin can change during high-risk periods.
