### Downloadable **CSV** files

### API Access and data format

Historical data format is the same as provided by real-time Bitstamp WebSocket **v2** with addition of local timestamps. If you'd like to work with **normalized data format** instead (same format for each exchange) see [downloadable CSV files](https://docs.tardis.dev/downloadable-csv-files/overview) or official [client libs](https://docs.tardis.dev/api/quickstart) that can perform data normalization client-side.

[Tardis-machine](https://docs.tardis.dev/tardis-machine/quickstart) is a locally runnable server that exposes API allowing efficiently requesting historical market data for whole time periods in contrast to [HTTP API](https://docs.tardis.dev/api/http-api-reference) that provides data only in minute by minute slices.

See [tardis-machine](https://docs.tardis.dev/tardis-machine/quickstart) docs.

### Captured real-time channels

{% embed url="<https://www.bitstamp.net/websocket/v2/>" %}
See Bitstamp WebSocket API docs providing documentation for each captured channel's format
{% endembed %}

{% hint style="info" %}
Click any channel below to see [HTTP API](https://docs.tardis.dev/api/http-api-reference#data-feeds-exchange) response with historical data recorded for it.
{% endhint %}

* [live\_trades](https://api.tardis.dev/v1/data-feeds/bitstamp?from=2024-01-01\&filters=\[{%22channel%22:%22live_trades%22}]) Public trade executions stream
* [diff\_order\_book](https://api.tardis.dev/v1/data-feeds/bitstamp?from=2024-01-01\&filters=\[{%22channel%22:%22diff_order_book%22}]) Order book delta stream
* [live\_orders](https://api.tardis.dev/v1/data-feeds/bitstamp?from=2024-01-01\&filters=\[{%22channel%22:%22live_orders%22}]) Level 3 live order events stream

Bitstamp real-time WebSocket API **does not provide initial full order book snapshots** for `diff_order_book` and `live_orders` channels subscriptions. To overcome this issue we fetch initial order book snapshots from REST API and store them together with the rest of the WebSocket messages. Such snapshot messages are marked with `"event": "snapshot"` and `"generated": true` fields for respective channels.

### Market data collection details

[Market data collection infrastructure](https://docs.tardis.dev/faq/general#what-is-your-infrastructure-setup) for Bitstamp is located in GCP europe-west2 region (London, UK).

Real-time market data is captured via **multiple WebSocket connections** to `wss://ws.bitstamp.net`.

{% hint style="info" %}
Bitstamp servers are located in AWS eu-central-1 region (Frankfurt, Germany).
