# Real-time WebSocket for trading events

> Upgrades to a WebSocket connection for streaming real-time trading events.

**Authentication:** pass JWT via query parameter `?token=YOUR_JWT` or via `Authorization` header.

**Optional filter:** add `&account_id=UUID` to receive events for a single account only.

**Events received:**
- `Welcome` — connection confirmed with account list
- `OrderSubmitted` / `OrderFilled` / `OrderCancelled` — order lifecycle
- `PositionUpdate` — real-time P&L changes on every tick
- `AccountUpdate` — balance, equity, drawdown changes
- `RuleViolation` — trading rule breach with reason
- `Notification` — system/copy-trade alerts

**Commands you can send:**
- `{"action": "subscribe", "account_id": "uuid"}` — filter to one account
- `{"action": "subscribe", "account_id": "*"}` — receive all (default)
- `{"action": "ping"}` — keep-alive

    # Hyperprop Trade API


    Authenticated trading API for prop firm evaluations. Execute trades, manage
    positions, and monitor account performance in real-time.


    ---


    ## Introduction


    The Hyperprop Trade API is a **high-performance trading engine** built from
    the ground up in **Rust** — the same language powering mission-critical
    systems at Discord, Cloudflare, and AWS. We chose Rust for one reason:
    **speed without compromise**.


    ### Why Rust?


    | Metric | Hyperprop (Rust) | Traditional APIs |

    |--------|------------------|------------------|

    | Engine processing | **< 1ms** | 5-20ms |

    | Typical end-to-end | **10-50ms** | 50-200ms |

    | Memory safety | **Guaranteed** | Runtime errors |

    | Concurrent users | **Thousands** | Hundreds |


    Our engine processes orders with **sub-millisecond internal latency**,
    handles thousands of concurrent WebSocket connections, and enforces trading
    rules in real-time — all while maintaining zero-copy memory efficiency.


    ### Architecture Highlights


    - **Zero-allocation hot path**: Order execution avoids memory allocation for
    maximum throughput

    - **Lock-free data structures**: Concurrent access without blocking

    - **Real-time rule enforcement**: P&L limits, drawdown checks, and position
    limits evaluated on every tick

    - **WebSocket-first design**: Instant event streaming with < 5ms delivery

    - **Async I/O**: Built on Tokio for efficient handling of 10,000+
    simultaneous connections


    ### What You Can Do


    - **Execute trades** with market, limit, and stop orders

    - **Monitor positions** with real-time P&L updates

    - **Stream events** via WebSocket for instant order fills, position changes,
    and rule violations

    - **Track multiple accounts** across different prop firms simultaneously

    ## Quick Start


    ```javascript

    // 1. Get your JWT token from your auth provider

    const token = 'your-jwt-token';


    // 2. Fetch your accounts

    const res = await fetch('/trade/accounts', {
      headers: { 'Authorization': `Bearer ${token}` }
    });

    const { data: accounts } = await res.json();


    // 3. Place a trade

    const order = await fetch('/trade/order', {
      method: 'POST',
      headers: { 
        'Authorization': `Bearer ${token}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        account_id: accounts[0].id,
        contract: 'ESH6',
        side: 'buy',
        quantity: 1
      })
    });

    ```


    ---


    ## Authentication


    All endpoints require a valid JWT token.


    **Header (recommended):**

    ```http

    Authorization: Bearer <your-jwt-token>

    ```


    **Query parameter (for WebSocket):**

    ```text

    /trade/ws?token=<your-jwt-token>

    ```


    ---


    ## Response Format


    All responses follow this structure:


    ### Success Response

    ```json

    {
      "success": true,
      "data": { ... },
      "error": null,
      "code": null
    }

    ```


    ### Error Response

    ```json

    {
      "success": false,
      "data": null,
      "error": "Human readable error message",
      "code": "ERROR_CODE"
    }

    ```


    ---


    ## Error Codes


    ### Authentication & Access


    | Code | HTTP Status | Description |

    | `ENGINE_AT_CAPACITY` | 400 | Too many commands are already in flight; the
    order was NOT accepted. Retry after a short backoff — the same
    `x-idempotency-key` is safe to reuse because nothing was queued. |


    ### Trading


    | Code | HTTP Status | Description |

    |------|-------------|-------------|

    | `TRADING_DISABLED` | 403 | Account status prevents trading (passed or
    failed) |

    | `MARKET_NOT_ENABLED` | 403 | Account does not have access to this
    contract's exchange (e.g., trying to trade COMEX contract on a CME-only
    account) |

    | `INVALID_SIDE` | 400 | Side must be `buy` or `sell` |

    | `INVALID_CONTRACT` | 400 | Contract symbol is unknown or not active |

    ## Account Status


    The engine returns these status values via REST and WebSocket. The database
    stores equivalent aliases shown in the DB column.


    | API Status | DB Value | Can Trade | Description |

    |------------|----------|-----------|-------------|

    | `Active` | `not_started` | ✅ | Account created, not yet traded |

    | `InProgress` | `in_progress` | ✅ | Actively trading |

    | `Completed` | `passed` | ❌ | Profit target reached — account passed
    (flat-confirmed) |

    | `Violated` | `failed` | ❌ | Rule violation — auto-liquidated, trading
    disabled |

    | `Violated` | `expired` | ❌ | Account expired — treated same as failed |

    ### Example Client


    ```javascript

    const protocol = location.protocol === 'https:' ? 'wss:' : 'ws:';

    const ws = new
    WebSocket(`${protocol}//${location.host}/trade/ws?token=${jwt}&account_id=${accountId}`);


    ws.onopen = () => console.log('Connected');


    ws.onmessage = (e) => {
      const msg = JSON.parse(e.data);
      
      switch (msg.type) {
        case 'Welcome':
          console.log('Accounts:', msg.accounts);
          break;
        case 'OrderFilled':
          console.log(`Filled: ${msg.order.side} ${msg.order.quantity} ${msg.order.contract} @ ${msg.trade.price}`);
          break;
        case 'PositionUpdate':
          console.log(`P&L: $${msg.position.unrealized_pnl.toFixed(2)}`);
          break;
        case 'AccountUpdate':
          console.log(`Equity: $${msg.equity.toFixed(2)}, Drawdown: $${msg.drawdown.toFixed(2)}`);
          break;
        case 'RuleViolation':
          alert(`⚠️ ${msg.reason}`);
          break;
        case 'Notification':
          // Display notification to user based on level
          const icon = msg.level === 'error' ? '❌' : msg.level === 'warning' ? '⚠️' : 'ℹ️';
          console.log(`${icon} ${msg.title}: ${msg.message}`);
          // Show toast/notification in UI
          break;
      }
    };


    // Switch accounts dynamically

    ws.send(JSON.stringify({ action: 'subscribe', account_id:
    'other-account-uuid' }));

    ```


    ---


    ## Trading Rules


    Each account has rules that are checked in real-time:


    | Rule | Type | Description |

    |------|------|-------------|

    | `profit_target` | $ | Target profit to pass evaluation |

    | `max_loss` | $ | Maximum total loss allowed |

    | `daily_loss` | $ | Maximum loss per day |

    | `max_drawdown` | % | Max drawdown from high water mark |

    | `daily_drawdown` | % | Max daily drawdown |

    | `max_contracts` | # | Maximum position size in mini-equivalent units |

    | `micro_conversion_ratio` | # | How many micros count as 1 unit toward
    `max_contracts` (default 10; e.g. 5 or 1 per firm plan) |


    When a rule is violated, positions are auto-liquidated and the account is
    marked as `Violated` or `Completed`.


    ---


    ## Contracts


    Supported CME futures contracts used by the engine:


    | Symbol | Name | Tick Size | Point Value |

    |--------|------|-----------|-------------|

    | ESH6 | E-mini S&P 500 | 0.25 | $12.50 |

    | NQH6 | E-mini Nasdaq | 0.25 | $5.00 |

    | YMH6 | E-mini Dow | 1.00 | $5.00 |

    | RTH6 | E-mini Russell | 0.10 | $5.00 |


    ---


    ## Data Persistence


    All trading data is persisted to ensure consistency and auditability:


    | Data | Storage | When |

    |------|---------|------|

    | **Order Snapshot** | Durable database | Latest state per `order_id`
    (upsert) |

    | **Order Events (Audit)** | Durable database | Every lifecycle transition
    (append-only) |

    | **Account State** | Durable database | On position close, rule violation,
    account completion |

    | **Positions** | In-memory | Real-time only (rebuilt from order history on
    restart) |


    ### Order Fields Persisted


    Every order includes:

    - `id`, `user_id`, `account_id`

    - `contract`, `product`, `symbol` (e.g., "ESH6", "CME", "ES")

    - `side`, `order_type`, `quantity`, `filled_quantity`

    - `limit_price`, `stop_price`, `filled_price`

    - `status`
    (pending_submit/new/working/pending/.../filled/cancelled/rejected)

    - `reason` (human-readable explanation)

    - `processed_at`, `engine_updated_at`, `filled_at`


    ---


    ## Rate Limits


    Rate limits are enforced **per trading account** using an in-memory token
    bucket algorithm. Each action category has its own independent bucket, so
    order submissions don't compete with cancellations.


    ### Limits by Action


    | Action | Burst Capacity | Refill Rate | Applies To |

    |--------|---------------|-------------|------------|

    | Order Submit | 10 | 10/sec | `POST /trade/order` |

    | Order Modify | 10 | 10/sec | `POST /trade/order/modify`,
    `/order/attach-bracket`, `/order/detach-bracket` |

    | Order Cancel | 20 | 20/sec | `POST /trade/order/cancel`,
    `/orders/cancel-all` |

    | Position Close | 5 | 2/sec | `POST /trade/position/close`,
    `/position/reverse`, `/close-all`, `/flatten` |

    | Copy Config | 10 | 2/sec | `POST /trade/copy/*` (create, update, toggle,
    delete) |

    | Lockout | 5 | 1/sec | `POST /trade/account/lockout`, `DELETE
    /trade/account/lockout` |


    Read endpoints (GET) are **not** rate limited.


    ### How It Works


    Each account starts with a full bucket (e.g., 10 tokens for order submit).
    Every request consumes 1 token. Tokens refill continuously at the specified
    rate. If the bucket is empty, the request is rejected with HTTP 429.


    ### Rate Limit Response (HTTP 429)


    ```json

    {
      \"success\": false,
      \"data\": null,
      \"error\": \"Rate limit exceeded for order submissions. Max 10 requests per second per account. Retry after 0.1 seconds.\",

    }

    ```


    ### Headers


    Successful requests do not include rate limit headers to minimize overhead.
    On 429 responses, inspect the error message for retry timing.


    ### Organization Overrides


    Organizations can have custom rate limits (e.g., higher limits for copy
    trading leaders). Contact the Hyperprop team for custom configurations.


    ### Important Notes


    - Limits are per **account**, not per user. A user with 5 accounts has 5
    independent buckets per action.

    - Different action categories have independent buckets. Exhausting order
    submit tokens does not affect cancellation tokens.

    - WebSocket events are **not** rate limited (server → client push).

        events.


        **Authentication:** pass JWT via query parameter `?token=YOUR_JWT` or
        via `Authorization` header.


        **Optional filter:** add `&account_id=UUID` to receive events for a
        single account only.


        **Events received:**

        - `Welcome` — connection confirmed with account list

        - `OrderSubmitted` / `OrderFilled` / `OrderCancelled` — order lifecycle

        - `PositionUpdate` — real-time P&L changes on every tick

        - `AccountUpdate` — balance, equity, drawdown changes

        - `RuleViolation` — trading rule breach with reason

        - `Notification` — system/copy-trade alerts


        **Commands you can send:**

        - `{"action": "subscribe", "account_id": "uuid"}` — filter to one
        account

        - `{"action": "subscribe", "account_id": "*"}` — receive all (default)

        - `{"action": "ping"}` — keep-alive
