Kairi is one of forex technical indicator used by many traders in forex technical analysis to help their trading. Kairi indicates the percentage difference between the current closing value and its simple moving average.

Overbought: When the underlying symbol is moving upwards, but the Kairi is approaching its upper bound, the underlying symbol is likely to reverse direction and move downwards.
Oversold: When the underlying symbol is moving downwards, but the Kairi is approaching its lower bound, the underlying symbol is likely to reverse direction and move upwards.

The Kairi Indicator can be used in order to take advantage of an over extended trending market. For example, in an upwardly trending market when the price gets say more than 10% above the simple moving average, the asset could be sold and repurchased when the next hits the simple moving average again.

The Kairi Indicator could also be used in order to detect market tops and bottom. The idea being that market tops and bottoms often occur when the price is at an extreme value in relation to its moving average. That is, the Kairi Indicator should take an extreme value at market tops and bottoms.
