In depth
The day high is set by a single trade, possibly a very small one, so it marks where a transaction happened rather than where the stock spent its time. Together with the day low it forms the day's range, which is the raw material for volatility measures such as average true range. A close near the day high after a wide range is read by technical traders as strength, but this is an interpretation of one day's data and nothing more. A day high touched on ten shares in an illiquid stock deserves far less attention than one set on heavy volume.
Worked example
A stock opens at ₹300, touches ₹318 briefly, falls to ₹296 and closes at ₹316. Day high is ₹318, day low is ₹296, and the range is 318 - 296 = ₹22, or 22 / 300 = 7.3% of the open.
