Overbought

A description of an oscillator reading above a conventional upper threshold, such as RSI above 70.

How it is identified Test: oscillator value exceeds its conventional upper threshold, typically 70 for RSI or 80 for stochastics
Unit qualitative

In depth

The word suggests a judgement about value that the indicator cannot make: overbought means only that recent gains have outweighed recent losses by a set ratio, which is what a rising security does by definition. This is why selling into overbought readings performs badly in sustained moves, where an oscillator can remain above its threshold for months. The threshold is a convention chosen decades ago for readability, not a level with any statistical standing. This dictionary uses the word to describe a reading and never to suggest that a price is too high or should be sold.

Worked example

RSI at 78 means average gains have been roughly 3.5 times average losses over the lookback window. In a strong advance the reading can hold above 70 for forty consecutive sessions while price rises another 25%.
