Is there is a way to set up precision of close price in EOD pricing template and universal close price in history pricing template by using REST API? Why universal close price in history pricing template is more accurate than close price in EOD pricing template with the same currency(e.g. universal close price of CAD is 0.123456 in history pricing template while close price of CAD is 0.12346 in EOD pricing template)?
You can set up precision (decimal places) when using extraction with the instrument list and report template. When creating a report template, you can specify decimal places of fields, as shown in the REST API reference page.
However, setting decimal places is not available in the On-Demand extraction.
