RSI: meaning, example and why it matters

Relative strength index: a 0 to 100 momentum indicator comparing recent gains with recent losses. Readings above about 70 are often called overbought and below about 30 oversold, but strong trends can stay at extremes for a long time.

Worked example

If over 14 periods the average gain is 2 and the average loss is 1, RS = 2 and RSI = 100 − 100 ÷ (1 + 2) = 66.7.

Illustrative numbers for explanation only. They are not market data, a forecast or a suggestion.

Why it matters

RSI compresses recent gains and losses into one 0 to 100 number so momentum can be compared across instruments.
