Data

What is Trade Data?

Trade Data is a general term for tick-by-tick data, or all trades occurring on an exchange. Our Trade Data products consist of all tick-by-tick trade data, normalized and timestamped. We provide trade data for all exchanges and currency pairs covered by Kaiko. 

What is an Order Book?

An order book is a list containing all outstanding buy or sell orders for a specific currency pair, organized by price level. An order book identifies the amount of the currency pair being bid or offered at a specific price, known as the market depth. An order to buy is called a ‘bid’ and an order to sell is called an ‘ask’. The exchange’s matching engine pairs up bids and asks, resulting in a trade.

All order books consist of Level 2 data. Our data is categorized in rows by: timestamp, order type (bid/ask), price, and amount. 

Kaiko provides order book snapshots at various market depths: 

  • 10% Order Books: orders placed at +/- 10% of the mid-price
  • 1% Order Books: order placed at +/- 1% of the mid-price (available upon request)
  • Full Order Books: all outstanding market orders (available upon request)

For the full definition of an Order Book, see Investopedia - Order Book Definition.

What is Historical Data?

Historical data refers to all available data up until a certain point in time. TRS guarantees all historical datasets contain data up to 1 day before purchase of our product. For example, if you buy All Historical Trade Data from the exchange Bitstamp, you will receive all trade data from the moment we began coverage of the exchange to a day before your purchase. 

We offer Historical Data for all of our products.

 

What is meant by 'bid' and 'ask'?

A ‘bid’ can be thought of as the highest price a buyer is willing to pay for a certain amount of an asset. This is in contrast to the ‘ask’, which is the lowest price a seller willing to sell an amount of an asset. The difference between these two is called the ‘spread’. In an Order Book, the ‘bid’ and ‘ask’ price are always accompanied by the amount of the asset being offered. In our Order Book datasets, bids are denoted as ‘b’ and asks as ‘a’.

Do you have data on futures?

Yes. We currently offer data on Bitmex and OKEx futures and will be adding to that list soon. 

Why are there different prices for different exchange data?

Kaiko prices our datasets in proportion to the amount of data processed and stored. Due to several reasons, some exchanges contain way more data than others; thus, those datasets will cost more.

Where do you get your data from?

We get our data from the public APIs provided by the exchanges.

If the exchanges' APIs are publicly available, why would I pay Kaiko for their data?

Fair point. However, collecting, storing, and normalizing immense amounts of data from all different exchanges and currency pairs is quite a task. We aim to provide data of the highest quality and completeness available on the market, and that takes time and resources.

How do you guarantee that the data is complete?

We strive to provide the most complete and qualitative data on the market. However, we partially rely upon the exchanges’ API to ensure this. Due to downtime of these API's (for example, due to maintenance) we sometimes experience gaps in our data and cannot always guarantee 100% coverage. 

We know that this can be problematic. That's why we are currently in the process of negotiating data distribution agreements directly with the exchanges in order to backfill past and missed trades. 

Is it possible to backfill missing data?

We are in the process of securing data distribution agreements with several major exchanges with the aim of backfilling gaps in the data. Customers having bought market data containing gaps will be notified when backfilling becomes available. 

Should you encounter any gaps in the obtained data, please do not hesitate to contact us and we will try to find a solution in a timely manner.
