Open-High-Low-Close sample used in financial charts.

Calculate the bounding interval of the OHLC values.
For valid samples the limits of this interval are always low/high.

A sample is valid, when all of the following checks are true:
Time of the sample, usually a number representing a specific interval - like a day.
