“Oversold means it’s about to bounce” — does it?
The RSI playbook is simple: below 30 is oversold (buy), above 70 is overbought (sell). It’s on every beginner’s first indicator list. We ran it across 391 coins with real fees and beta-stripped the result.
The result
RSI oversold/overbought entries: a 47% win rate, and once you subtract the market’s own move, the edge was negative. Mechanically tradeable, but a money-loser after costs.
The flaw: oversold can stay oversold
Here is the property of RSI that the strategy ignores: in a real trend, RSI pins to its extreme and stays there. An asset crashing hard will print “oversold” RSI for days while it keeps falling — you buy the first oversold reading and catch a falling knife. The same in reverse during a parabolic rally: RSI screams “overbought” while price doubles.
RSI is a momentum oscillator, and it works as a description in a ranging market. But you don’t know in advance whether you’re in a range (where the bounce comes) or a trend (where oversold is a trap). Across all conditions, the trend traps cancel the range bounces, and after fees you’re left with negative expectancy.
The win-rate illusion
47% feels close to a coin flip, but notice you can make RSI look better by exiting fast on the bounces — which raises the win rate while the rare trend-traps deliver outsized losses. That’s the conservation law: you can dial the win rate but not the expectancy.
The honest takeaway
RSI is a fine description of momentum and a poor entry signal. “Oversold” is not a buy button — it’s a label that holds in ranges and fails in trends, and you can’t tell which you’re in until afterward. Test it yourself on the simulator and look past the win rate to the return after fees.
So what does work?
If indicators, patterns, and copy-trades all fail an honest test, the obvious question is: then what? Our answer isn’t a sharper prediction — it’s risk management. After testing 34 strategies, the only thing that survived wasn’t forecasting the next move; it was controlling how you hold — sidestepping the worst drawdowns and surviving the cycle. That’s crisis defense, not a crystal ball, and we never call it more than it is.
- The honest answer: a risk-managed portfolio — survive the bear, compound through the cycle, half the drawdown of buy-and-hold.

- Check it yourself: the simulator — your strategy, real fees, real coins.
