Crypto RSI Divergence in Practice: BTC and ETH Cases
Crypto trades 24/7 with no daily limits, so once a trend starts, RSI "flatlines" above 70 for even longer than in stocks. Treating 70 as a sell and 30 as a buy loses money faster in crypto.
In a trend, RSI is evidence of strength
In a bull leg, BTC's daily RSI can sit in the 70–90 zone for a long time — this isn't "due to reverse," it's an extremely strong trend. Real opportunities often come when RSI pulls back to 40–50 and strengthens again (a bull retest), not on the first touch of 70.
Divergence in three steps (ETH top divergence)
- Price makes a new high; mark the two highs;
- Read RSI at those points: new price high with a lower RSI high = bearish divergence;
- Wait for confirmation: divergence is only a momentum-fading warning; it counts only after price breaks the prior swing low. In crypto, divergence can flatline three or four times — shorting the top directly is a classic way to get liquidated.
Period and overlays
The default 14 is fine; rather than optimize it, confirm across timeframes (4H divergence + daily trend). Set an alert on the RSI value (e.g. "crosses above 50"). RSI sets momentum, structure sets location; combine with the basis and sentiment for higher win rates.
