What is this page?
This section presents the most updated quality tests for our cryptocurrency bar generator engine. Additionally, it summarizes
the different types of bars and steps offered (each step has a different meaning depending on the bar type. More info in the API docs ) .
When data is updated by pulling raw trades from the exchanges (for now only Bitfinex), bars are automatically built and data quality is
evaluated based on volume conservation . Essentially, we check that the sum of all trades volume is equal to the sum
of all bars volume. If the difference observed is low, then we have a guarantee that the bars have been built correctly and have included all the existing trades
provided by the exchange, no more and no less. However, note that small errors can be observed due to floating point operations.
We set our error tolerance to 0.01 — any error higher than this threshold should raise our concern and the affected bars should be revised and possibly
regenerated from scratch using the raw trade data.
