Retrieves order book update/events (bid and ask). The volume of this data is very large for many exchanges and pairs.
Time Range Limit
The maximum time range (difference between startDate and endDate) is 1 hour.
In order to get more than the maximum allowed, you can use the
startDate&endDateparameters to move the time frame window to get the next n days/hours/minutes of data.This endpoint is used to retrieve historical data only and is updated every hour. If your query does not return any data, try the hour before using the
startDate&endDateparameters.
Not specifying startDate and endDate
If the startDate and endDate query parameters are not provided, the API will return the data from the previous hour.
*Note: The internal array of price, volume, and numOrders could be larger than 1 element if the exchange batches these events.
