Key levels: prior session and 52-week range

The few past prices traders watch most, and what they do and don't tell you

Prior session high, low and close

The highest, lowest and last prices of the last complete trading day. Many traders compare today's price to these three, so they often come up in market commentary.

52-week range

The highest and lowest prices over the last year of daily bars. Where today's price sits in that range (near the top, middle or bottom) is a quick way to describe the past year.

Limits

A level is a price that mattered before. It doesn't mean the price will stop, turn or break there. Coteau shows these from daily bars (Yahoo Finance, delayed) and labels them as past prices.
