With `-V` (and `--value` with COMM unspecified), hledger picks a

valuation commodity automatically. Typically your P directives

give prices in a single base currency, and -V will use that.

### Effect of valuation on reports
 | 
			
		||||
 | 
			
		||||
Here is a reference for how `--value` currently affects each part of hledger's reports.
 | 
			
		||||
It's work in progress, but may be useful for troubleshooting or reporting bugs.
 | 
			
		||||
See also the definitions and notes below.

Here is a reference for how valuation is supposed to affect each part of hledger's reports (and a glossary).
 | 
			
		||||
(It's wide, you'll have to scroll sideways.)
 | 
			
		||||
It may be useful when troubleshooting.
 | 
			
		||||
If you find problems, please report them, ideally with a reproducible example.
