In what format do EU Stock Brokers like IB exchange information according to CRS?

[DavidS]

European Union stock brokers like IB - what is the template on their automatic CRS information exchange?

How do they provide this information? Do they show only cash balance or turnover or stock positions and total sum at the day of reporting?

Or do they simply show the amount of stocks without showing the sum?

How does it work exactly?

Thank you.

Always assume they all report the entire account value and act accordingly

You can see the exact format below that CRS data is reported in.
