Savvy traders use a bunch of tools to analyze markets. The relative strength index (RSI) is one of the most popular ones, sniffing out trend strength and momentum extremes.
Right now, the RSI is signaling that bitcoin is oversold, suggesting the recent sell-off has been too intense, and prices could see a relief bounce. But don’t bet the farm: the oversold reading doesn’t promise a full-blown bull run.
Mechanical engineer and renowned 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 period, producing a value that oscillates between 0 and 100. A reading below 30 signals that price losses have outpaced gains too aggressively over the past 14 days, a sign of strong bearish momentum.
Wilder and RSI adherents call it oversold: the market has plunged too far, too fast relative to recent norms, priming it for mean reversion or a rebound.
The market often bounces when the RSI prints oversold conditions, even though a reading below 30 by itself only indicates what has recently happened.
The logic behind such oversold bounces is simple: trader interpretation turns it into a self-fulfilling prophecy, as enough desks and algos pile into oversold bounces, making the rebound happen.
It’s especially true when an oversold reading appears while the asset trades near key support – a price level where buyers previously stepped in to arrest the slide at that time.
That’s precisely the situation with bitcoin right now.
The chart shows BTC’s daily price swings in candlestick format, with the 14-day RSI in the lower pane. A candlestick chart visually captures an asset’s price action over a set period, such as a day or an hour, showing the open, close, high, and low prices in a single compact shape that resembles the candles we use in everyday life.
The RSI has dropped below 30, signaling oversold conditions, while bitcoin trades near the $73,000-$75,000 support zone. The April 2025 slide fizzled out in this range, and the early 2024 bull run stalled in the same range. This cements it as a pivotal battleground of buying and selling over the past two years.
Thus, the self-fulfilling prophecy could play out, leading to a notable price bounce.
That said, a bounce is not promised, and a potential bounce doesn’t necessarily indicate the beginning of a new bull run. Just as any other indicator, the RSI can produce fake signals.
Besides, context matters. Oversold readings have historically yielded only meagre bounces amid broader bearish trends, as in 2022. The last one, in November, ushered in a multi-week consolidation that ultimately gave way to last month’s deeper sell-off.
