What is Above upper Bollinger? — chart signal explained
Bollinger Bands map out the usual lane that price travels in: a middle line (the average of the last 20 candles) with an upper and a lower band, each placed two standard deviations away — about twice a typical wiggle. Statistically, price stays inside that lane most of the time.
When does it fire? — BaroBara criteria
The signal fires when a candle closes above the upper band, meaning more than two standard deviations above the 20-candle average.
How traders usually read it
Traders read this one in two opposite ways. Some expect a cooldown — 'it's stretched further than usual, a pullback may be due' — while others see it as strength: it takes real buying pressure to push price outside the band, so they expect the climb to continue.
What to watch out for
In powerful uptrends, price frequently rides along the upper band for extended stretches (band walking), so calling it 'too expensive' the moment it touches the band can leave you leaning the wrong way through the whole move. And since the two readings contradict each other, this signal on its own is thin ground for any directional call.
What the data actually shows (BTC 1d)
The common reading is a drop — but what actually happened matters more. This signal has fired 30 times on BTC 1d; across the most recent 30, price reached the small target (+0.25%) first about 60% of the time. Widen the target to ±1% and it becomes about 63%. A historical probability, not a guaranteed direction — and it shifts with market regime.
Odds and expected value — with symmetric target and stop (±)
Exactly the barobara framing: which side got hit first, +X% or −X%. Target and stop are set to the same %, and the win rate is how often the upside (+X%) was reached first.
| Target = stop (±) | Win rate (+ first) | EV (before fees) |
|---|---|---|
| ±0.25% | 60% | +0.05% |
| ±0.5% | 60% | +0.10% |
| ±0.75% | 60% | +0.15% |
| ±1% | 63% | +0.26% |
| ±1.5% | 57% | +0.21% |
| ±2% | 57% | +0.28% |
Broken down by market regime
⚠️ This table uses a different basis than the symmetric (±) table above — a small +0.25% target with a wide −5.0% stop (fees included). The small target makes the win rate look high while EV is often negative — exactly what signal groups hide. And the same signal behaves differently across regimes.
| Regime | Win rate (+0.25% target) | EV (−5.0% stop) | Sample |
|---|---|---|---|
| Sideways | 89% | -0.41% | N=9 |
| Bull market | 65% | -1.68% | N=17 |
