.PP 
Open-High-Low-Close sample used in financial charts\&. 

In financial charts the movement of a price in a time interval is often represented by the opening/closing prices and the lowest/highest prices in this interval\&.

.PP
Check if a sample is valid\&. A sample is valid, when all of the following checks are true:
.PP
.IP "\(bu" 2
low <= high
.IP "\(bu" 2
low <= open <= high
.IP "\(bu" 2
low <= close <= high
