Savvy traders use many tools to analyze the markets. The relative strength index (RSI) is one of the most popular, detecting the strength of trends and extremes of momentum.
Currently, the RSI is signaling that bitcoin is oversold, suggesting that the recent sell-off has been too intense and prices could see a relief rebound. But don’t bet on the farm: oversold numbers don’t promise a true bull run.
Renowned mechanical engineer and technical analyst J. Welles Wilder Jr invented the RSI in 1978, revealing the formula and interpretation in his book “New Concepts in Technical Trading Systems.”
The indicator measures price gains and losses over a standard 14-day time frame, producing a value that ranges between 0 and 100. A value below 30 indicates that price losses have exceeded gains too aggressively over the past 14 days, a sign of strong bearish momentum.
Proponents of Wilder and the RSI call it oversold: the market has plunged too far, too quickly by recent standards, setting it up for a mean reversion or rebound.
The market often rebounds when the RSI displays oversold conditions, although a reading below 30 alone only indicates what has happened recently.
The logic behind such oversold bounces is simple: traders’ interpretation makes it a self-fulfilling prophecy, as enough bureaus and algorithms pile into oversold bounces, allowing the bounce to occur.
This is especially true when an oversold figure appears while the asset is trading near key support – a price level at which buyers had previously stepped in to stop the fall at that time.
This is precisely the current situation of Bitcoin.
The chart shows daily BTC price fluctuations in candlestick form, with the 14-day RSI in the lower pane. A candlestick chart visually captures the price action of an asset over a period of time, such as a day or an hour, showing the open, close, high, and low prices in a unique compact form that resembles the candles we use in daily life.
The RSI has fallen below 30, signaling oversold conditions, while bitcoin is trading near the $73,000-$75,000 support zone. The April 2025 fall stopped in this range, and the early 2024 rise stopped in the same range. This makes it a crucial battleground for buying and selling over the past couple of years.
Thus, the self-fulfilling prophecy could come true, leading to a notable rebound in prices.
That said, a rebound is not promised, and a potential rebound does not necessarily indicate the start of a new uptrend. Like any other indicator, the RSI can produce false signals.
Additionally, context matters. Oversold stocks have historically given only meager bounces amid broader downtrends, such as in 2022. The last one, in November, marked the start of a multi-week consolidation that eventually gave way to a larger sell-off last month.
