What is RSI?

The relative strength index (RSI) is a technical analysis indicator that shows the strength of a trend and the probability of it changing.

RSI is seen as an oscillator, which means that it's strength is showing reversal and entry points.

It is represented visually as a line that follows a chart, moving within the boundaries of the values 0 and 100.

The RSI line periodically goes beyond the boundaries of 30 and 70, crossing the upper or lower level.
