Introducing point-in-time support
Point-in-time allows you to avoid look-ahead bias in your alternative data analysis workflows. We have now rolled out beta point-in-time support to the Data API, Exabel SDK, and Signal Explorer!
In December, we updated the Data API and Exabel SDK to allow all users to import time series data with an additional "known time" property, specifying the date from which each data point would have been known & available.
In Signal Explorer, you are also now able to evaluate signals as of a specific point-in-time, which is a good way to start exploring & understanding how the underlying time series data look at different points in time.
In December 2021, we queried for Apple's share price up till 31 Dec 2021. However, the signal evaluates to show only share prices available at the specified point-in-time date of 30 Sep 2021.
