# DXtrade API POST /marketdata

Independent and unofficial. Not affiliated with or endorsed by any broker or platform named here. Educational only: nothing here is advice, and nothing here recommends a broker or a trade.

This is the markdown version of https://openbrokerapi.com/platforms/dxtrade/endpoints/post-marketdata, written from the same records as that page.

Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

Ask for current quotes or for historical candles for one or more instruments. One call serves both, chosen by the event type in the body.

- Request: `POST /marketdata`
- Group: Market Data
- Status: verified. Source: [demo.dx.trade](https://demo.dx.trade/developers/#/DXtrade-REST-API), checked 2026-10-12.
- Official reference: https://demo.dx.trade/developers/#/DXtrade-REST-API?id=request-market-data

Note: Read on 12 Oct 2026 in the DXtrade REST API specification on DXtrade's developer portal. The portal draws its pages in the browser from Markdown files it also serves directly, and the Markdown file of this page (DXtrade-REST-API.md) is what was read, with the model files it includes. The portal writes each address after a base address it fills in from its own settings, which on this portal is https://demo.dx.trade/dxsca-web. A broker or firm that offers DXtrade hosts its own, so the path here is what follows that base. The specification says every request needs authentication unless it says otherwise, and this section says the Authorization header should be included, which is why it is recorded as required. The body is the Market Data Request model and its Market Data Event Type, with the models' own marks. The reply is a market data list. The page says a request for symbols with no quotes is answered 404 with error code 35.

## Parameters

- `eventTypes` (in body, type array, required): The kinds of data wanted, each an object with the fields below.
- `eventTypes[].type` (in body, type string, required): Either Quote or Candle.
- `eventTypes[].format` (in body, type string, optional): Marked optional. Always COMPACT.
- `eventTypes[].candleType` (in body, type string, optional): Marked optional. The candle size, for candle requests. One of: m, 5m, 15m, 30m, h, 2h, 4h, d, w, mo.
- `eventTypes[].fromTime` (in body, type string, optional): Marked optional in the table, which also says it is required for Candle. UTC time the history starts at.
- `eventTypes[].toTime` (in body, type string, optional): Marked optional in the table, which also says it is required for Candle. UTC time the history ends at.
- `eventTypes[].count` (in body, type number, optional): Marked optional. The most candles to return. When the period holds more, the older ones are dropped.
- `symbols` (in body, type string, required): Instrument symbols, as a list of strings or one comma separated string.
- `account` (in body, type string, optional): Marked optional. An account code, used only where a user's accounts have different pricing.

### Authentication headers

- `Authorization` (type string, required): With token authentication, send DXAPI followed by the sessionToken from POST /login. With HMAC authentication the same header carries DXAPI with a principal, a timestamp and a hash, signed for each request as the specification describes. Placeholder only: never paste a real token into this site.

## Request

Written from the method, path and parameters recorded on this page. No demo host is recorded as a plain address for this API, so the samples read the base address from an environment variable. Not executed against a live or demo account. Credentials are read from environment variables on your own machine and are never entered on this site. The request builder at https://openbrokerapi.com/tools/request-builder writes these same snippets, from the same record.

This call takes a request body. The samples send it as JSON with a placeholder for each of the 3 body fields the record marks as required. Each placeholder has to be replaced with a real value before the request can succeed.

### Python

```python
# Set DXTRADE_BASE_URL, DXTRADE_SESSION_TOKEN as environment variables first. Never paste real values into code.
# DXTRADE_SESSION_TOKEN holds the Authorization header that POST /login returns.
# No demo host is recorded as a plain address for this API, so the base address is read from DXTRADE_BASE_URL.
# Replace each {placeholder}, "..." and 0 with a real value before running.
# Optional and not shown: body fields eventTypes[].format, eventTypes[].candleType, eventTypes[].fromTime, eventTypes[].toTime, eventTypes[].count, account.
import os
import requests

BASE_URL = os.environ["DXTRADE_BASE_URL"]
headers = {
    "Authorization": "DXAPI " + os.environ["DXTRADE_SESSION_TOKEN"],
}
body = {"eventTypes": [{"type": "..."}], "symbols": "..."}
resp = requests.post(BASE_URL + "/marketdata", headers=headers, json=body, timeout=10)
resp.raise_for_status()
print(resp.json())
```

### JavaScript

```javascript
// Set DXTRADE_BASE_URL, DXTRADE_SESSION_TOKEN as environment variables first. Never paste real values into code.
// DXTRADE_SESSION_TOKEN holds the Authorization header that POST /login returns.
// No demo host is recorded as a plain address for this API, so the base address is read from DXTRADE_BASE_URL.
// Replace each {placeholder}, "..." and 0 with a real value before running.
// Optional and not shown: body fields eventTypes[].format, eventTypes[].candleType, eventTypes[].fromTime, eventTypes[].toTime, eventTypes[].count, account.
// Run as a module, for example a .mjs file, on a Node version that has fetch built in.
const BASE_URL = process.env.DXTRADE_BASE_URL;
const res = await fetch(BASE_URL + "/marketdata", {
  method: "POST",
  headers: {
    "Authorization": "DXAPI " + process.env.DXTRADE_SESSION_TOKEN,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({"eventTypes": [{"type": "..."}], "symbols": "..."}),
});
if (!res.ok) throw new Error(`HTTP ${res.status}`);
console.log(await res.json());
```

### curl

```bash
# Set DXTRADE_BASE_URL, DXTRADE_SESSION_TOKEN as environment variables first. Never paste real values into code.
# DXTRADE_SESSION_TOKEN holds the Authorization header that POST /login returns.
# No demo host is recorded as a plain address for this API, so the base address is read from DXTRADE_BASE_URL.
# Replace each {placeholder}, "..." and 0 with a real value before running.
# Optional and not shown: body fields eventTypes[].format, eventTypes[].candleType, eventTypes[].fromTime, eventTypes[].toTime, eventTypes[].count, account.
curl -X POST "$DXTRADE_BASE_URL/marketdata" \
  -H "Authorization: DXAPI $DXTRADE_SESSION_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"eventTypes": [{"type": "..."}], "symbols": "..."}'
