### GET /v0/orders

Source: https://docs.dreamdex.io/developers/http-api/trading.md

Lists orders for the authenticated account across one or more markets, with optional filtering by status and pagination via cursor.

```APIDOC
## GET /v0/orders

### Description
Returns orders for the authenticated account across one or more markets, newest-first. If no symbols are specified, returns orders for all available markets. Unknown symbols are silently skipped. Optionally filter by order status. The response includes a `nextCursor` token when more pages are available — pass it back as `cursor` to continue.

### Method
GET

### Endpoint
/v0/orders

### Parameters
#### Query Parameters
- **symbols** (array of Symbol) - Optional - Market symbols to filter. When omitted, returns orders for all markets.
- **status** (OrderStatus) - Optional - Order status to filter by. Allowed values: `open`, `closed`, `canceled`, `expired`, `rejected`.

- **orders** (array) - List of orders. Each order includes its current state, fill progress, and associated transaction hash.
- **nextCursor** (string) - Opaque pagination token. Pass this back as the `cursor` query parameter on the next request to retrieve the page after this one. The string is intentionally opaque — clients must not parse or modify it.

### Notes
- Requires bearer authentication (account scope).
- Servers: Mainnet `https://api.dreamdex.io`, Testnet `https://stg.api.dreamdex.io`.
- Market symbols are in `BASE:QUOTE` form using the exchange's currency codes (e.g., `SOMI:USDso`). The authoritative list is served by `GET /v0/markets` and `GET /v0/currencies`; do not assume codes are stable across environments.
```

--------------------------------

### GET /v0/markets/{symbol}/trades/{address}

Source: https://docs.dreamdex.io/developers/http-api/trading.md

Returns executed trades for the given wallet address within a market over a half-open time range [since, until). Requires a bearer token with the trades:read_any scope. Trades are returned newest-first, and the response is an empty array when no trades match.

```APIDOC
## GET /v0/markets/{symbol}/trades/{address}

### Description
Returns executed trades for the given wallet address within a market over a half-open time range `[since, until)`. Includes trades where the wallet was either the taker or the maker. Trades are returned newest-first (reverse chronological order); the response is an empty array when no trades match.

Access is restricted to bearer tokens carrying the `trades:read_any` scope. Tokens without the scope receive 403. Because the scope is required, each trade always includes the `maker` and `taker` wallet addresses.

`until` defaults to the current time if omitted; `since` defaults to `until - 7 days`. The range must not exceed 40 days — longer ranges return 400. Use `as=maker` or `as=taker` to restrict the result to one side; both sides are returned by default.

### Method
GET

### Endpoint
/v0/markets/{symbol}/trades/{address}

### Parameters
#### Path Parameters
- **symbol** (Symbol) - Required - Market symbol in `BASE:QUOTE` form using the exchange's currency codes (e.g. `SOMI:USDso`). The authoritative, per-environment list of live symbols and currency codes is served by `GET /v0/markets` and `GET /v0/currencies`; do not assume codes are stable across mainnet and testnet. As of writing, mainnet lists `SOMI:USDso`, `WETH:USDso`, `WBTC:USDso`, and `USDC.e:USDso`.
- **address** (Address) - Required - Wallet address whose trades to return. EVM-compatible address (0x-prefixed, checksummed).

#### Query Parameters
- **since** (integer, int64) - Optional - Return trades after this unix millisecond timestamp.
- **until** (integer, int64) - Optional - Return trades strictly before this unix millisecond timestamp (exclusive). Defaults to the current time when omitted.
- **as** (string) - Optional - Restrict results to trades where the wallet was on this side. Omit to return trades where the wallet was either maker or taker. Enum: `maker`, `taker`.

### Response
#### Success Response (200)
- **trades** (array of Trade) - A list of executed trades. Each trade has the following properties:
  - **id** (string) - Unique trade identifier.
  - **symbol** (Symbol) - Market symbol.
  - **side** (TradeSide) - Side of the trade.
  - **price** (Price) - Trade price.
  - **amount** (Quantity) - Trade amount.
  - **cost** (Quantity) - Trade cost.
  - **maker** (Address) - Wallet address of the resting (maker) order owner. Only present when the request carries a bearer token with the `trades:read_any` scope; omitted otherwise.
  - **taker** (Address) - Wallet address of the aggressing (taker) order owner. Only present when the request carries a bearer token with the `trades:read_any` scope; omitted otherwise.
  - **timestamp** (Timestamp) - Trade timestamp.
  - **txHash** (string) - On-chain transaction hash of the fill.

#### Response Example
```json
{
  "trades": [
    {
      "id": "string",
      "symbol": "SOMI:USDso",
      "side": "buy",
      "price": "100.00",
      "amount": "1.5",
      "cost": "150.00",

      "timestamp": 1234567890,
      "txHash": "0x..."
    }
  ]
}
```

### Error Handling
- **403** - Returned when the bearer token does not carry the `trades:read_any` scope.
- **400** - Returned when the time range exceeds 40 days.

### GET /v0/markets/{symbol}/tickers

Source: https://docs.dreamdex.io/developers/http-api/trading.md

Returns 24-hour OHLCV market statistics for a specific trading pair. Includes open, high, low, close prices and total trade volume. All fields are "0" if no trades occurred in the period.

```APIDOC
## GET /v0/markets/{symbol}/tickers

### Description
Returns 24-hour OHLCV market statistics for a specific trading pair. Includes open, high, low, close prices and total trade volume. All fields are "0" if no trades occurred in the period.

### Method
GET

### Endpoint
/v0/markets/{symbol}/tickers

### Parameters
#### Path Parameters
- **symbol** (string) - Required - Market symbol in `BASE:QUOTE` form using the exchange's currency codes (e.g. `SOMI:USDso`). The authoritative, per-environment list of live symbols and currency codes is served by `GET /v0/markets` and `GET /v0/currencies`; do not assume codes are stable across mainnet and testnet. As of writing, mainnet lists `SOMI:USDso`, `WETH:USDso`, `WBTC:USDso`, and `USDC.e:USDso`.

### Response
#### Success Response (200)
- **symbols** (array of TickerInfo) - List of tickers for the requested symbols.

Each TickerInfo object contains:
- **symbol** (Symbol) - Market symbol in `BASE:QUOTE` form
- **timestamp** (integer) - Time the ticker was computed (server "as of" time), not a trade time. Unix Timestamp (ms).
- **lastTradeAt** (integer, nullable) - Time of the most recent trade on this market, regardless of the 24h window. Null if the market has never traded. Use this to distinguish "no trades recently" (stale OHLCV, but the market exists and may have depth) from "never traded".
- **open** (string) - 24-hour opening price (first trade), "0" if no trades in the period. Price as decimal string.
- **high** (string) - 24-hour high price, "0" if no trades in the period. Price as decimal string.
- **low** (string) - 24-hour low price, "0" if no trades in the period. Price as decimal string.
- **close** (string) - 24-hour closing price (last trade), "0" if no trades in the period. Price as decimal string.
- **volume** (string) - 24-hour total trade volume, "0" if no trades in the period. Quantity as decimal string.

#### Response Example
{
  "symbols": [
    {
      "symbol": "SOMI:USDso",
      "timestamp": 1700000000000,
      "lastTradeAt": 1700000000000,

      "volume": "100.5"
    }
  ]
}

### Error Response (400)
When any requested symbol is not a known market, the whole request is rejected with 400 `invalid_param`. The all-markets path (no `symbols` filter) always returns 200.
