What Is RSI? How to Read the RSI Indicator (30 and 70 Levels)

Updated: 2026-10-26 · Türkçe

RSI (Relative Strength Index) is a momentum indicator that turns the strength of the last 14 candles' gains and losses into a number between 0 and 100. J. Welles Wilder introduced it in 1978. Below are today's daily RSI readings for major instruments, followed by how RSI is calculated and read.

Today's daily RSI readings

How RSI is calculated

On each candle, a higher close than the previous one counts as a gain and a lower close as a loss. Gains and losses are averaged over 14 periods with Wilder's smoothing (each new value enters with 1/14 weight). RS = average gain ÷ average loss; RSI = 100 − 100 ÷ (1 + RS).

A series that only rises pushes RSI toward 100; one that only falls pushes it toward 0. ByStock calculates RSI the same way as TradingView's ta.rsi.

What the 30 and 70 levels mean

The classic reading: above 70 is overbought, below 30 is oversold. It says price moved fast in one direction; it does not say a reversal is coming. In strong trends RSI can stay above 70 or below 30 for weeks.

RSI	Zone	Common reading
Above 70	Overbought	Fast rise; strong trend or a pause ahead
50–70	Bullish side	Buyers in control
30–50	Bearish side	Sellers in control
Below 30	Oversold	Fast drop; a bounce or further decline

RSI divergence

When price makes a higher high but RSI makes a lower high, that's bearish divergence; a lower low in price with a higher low in RSI is bullish divergence. It signals fading momentum, but timing is uncertain and most divergences don't end in a reversal.

Which timeframe?

Hourly and daily RSI on the same instrument can differ a lot; shorter timeframes hit extremes more often. ByStock's RSI scanner lists the top 60 Binance perpetuals on both 4-hour and daily RSI.

Limits of RSI

RSI is not a trading system on its own. Read it with trend direction (e.g. the 200-day average), volume and support/resistance. This page is educational, not investment advice.

Frequently asked questions

At what RSI should you buy or sell?

There's no fixed level. Below 30 reads as oversold and above 70 as overbought, but in strong trends RSI can stay there for a long time. It isn't used as a signal on its own.

Why is RSI set to 14?

14 is Wilder's default period and the most common setting. Shorter periods (e.g. 7) are faster and noisier; longer ones (e.g. 21) are slower.
