Prefer the current replacement endpoints where available. **Rate limit:** 20 requests per 60 seconds. This is a **shared quota** — the same budget is consumed by a group of related endpoints, so calling any of them reduces what is left for the others (you cannot call each at the full rate independently). Endpoints sharing this quota: - `DELETE /api/v1/trading/execution/limit-orders/{orderId}` - `DELETE /api/v1/trading/execution/market-close-orders/{orderId}` - `DELETE /api/v1/trading/execution/market-open-orders/{orderId}` - `DELETE /api/v2/trading/execution/orders/{orderId}` - `POST /api/v1/trading/execution/limit-orders` - `POST /api/v1/trading/execution/market-close-orders/positions/{positionId}` - `POST /api/v1/trading/execution/market-open-orders/by-units` - `POST /api/v2/trading/execution/orders` --- This endpoint allows traders to place a market order to open a position by specifying the investment amount instead of specifying the number of units. The trade will be executed at the market price, and leverage, stop-loss, and take-profit settings can be applied. A 200 response means the order was submitted, not that the position was opened. Confirm the outcome with GET /api/v1/trading/info/real/orders/{orderId}, using the orderID returned under orderForOpen. ## OpenAPI ````yaml /api-reference/deprecated-openapi.json post /api/v1/trading/execution/market-open-orders/by-amount openapi: 3.0.1 info: title: eToro Api version: v1.352.0 description: >- eToro’s public API provides access to real-time financial data, trading insights, and account management features, allowing developers to integrate eToro’s services into their applications. With access to market prices, historical data, and social trading information, the API empowers users to enhance their trading strategies. Designed for security and scalability, the eToro API ensures smooth and reliable integration for a variety of financial applications. For more details on integrating with eToro's public WebSocket service, please refer to the dedicated [WebSocket documentation](./websocket/websocket-doc.html). ## Authentication Every request must be authenticated with exactly one of two options: an OAuth 2.0 access token (`Authorization: Bearer `), or the non-interactive credential pair (`x-api-key` + `x-user-key` headers). The two options are mutually exclusive — a request carrying both is rejected. Each operation lists the OAuth scopes that grant access as alternative security requirements: a bearer token needs only ONE of them, and the same permissions govern the credential pair. servers: - url: https://public-api.etoro.com description: eToro Public API - Deprecated security: - apiKeyAuth: [] userKeyAuth: [] - oauth2: [] tags: - name: Agent Portfolios - name: Social Feeds - name: Trading - Demo - name: Trading - Real paths: /api/v1/trading/execution/market-open-orders/by-amount: post: tags: - Trading - Real summary: Open market order by cash amount description: >- Deprecated: This endpoint is marked deprecated in the eToro Public API Swagger.
