Downloadable CSV files

Quick start
CSV datasets are available via dedicated datasets API that allows downloading tick level incremental order book L2 updates, order book snapshots, trades, options chains, quotes, derivative tickers and liquidations data.

For ongoing data, CSV datasets for a given day are available on the next day around 05:00 UTC.
CSV datasets are exported from exchanges' real-time WebSocket feeds data we collected (and also provide via our API as historical data in exchange-native format).
Historical datasets for the first day of each month are available to download without API key. 

Our Node.js and Python clients have built-in functions to efficiently download whole date range of data.

Data types
• incremental_book_L2 
Incremental order book L2 updates collected from exchanges' real-time WebSocket order book L2 data feeds - data as deep and granular as underlying real-time data source, please see FAQ: What is the maximum order book depth available for each supported exchange? for more details.
Learn in more detail how incremental_book_l2 CSV dataset is built from real-time data.
As exchanges real-time feeds usually publish multiple order book levels updates via single message you can recognize that by grouping rows by local_timestamp field if needed. 
If you have any doubts how to correctly reconstruct full order book state from incremental_book_L2 CSV dataset, please see this answer or contact us.

In case you only need order book data for top 25 or top 5 levels, we do provide datasets with already reconstructed snapshots for every update for those. See book_snapshot_25 and book_snapshot_5.

​
exchange
exchange id, one of https://api.tardis.dev/v1/exchanges ([].id field)
​
symbol
instrument symbol as provided by exchange (always uppercase)
​
timestamp
timestamp provided by exchange in microseconds since epoch - if exchange does not provide one local_timestamp value is used as a fallback 
​
local_timestamp
message arrival timestamp in microseconds since epoch
​
is_snapshot
possible values:
true - if update was a part of initial order book snapshot
false - if update was not a part of initial order book snapshot
If last update was not a snapshot and current one is, then existing order book state must be discarded (all existing levels removed)
​
side
determines to which side of the order book update belongs to:
bid - bid side of the book, buy orders
ask - ask side of the book, sell orders
​
price
price identifying book level being updated
​
amount
updated price level amount as provided by exchange, not a delta - an amount of 0 indicates that the price level can be removed
