What is 20-bar low breakdown? — chart signal explained
This one also skips the indicators and watches price directly. Take the lowest price of the last 20 bars as a floor, and check whether the current close has fallen through it. It means a floor that held for a while has finally given way.
When does it fire? — BaroBara criteria
It fires when the close touches or drops below the lowest low of the last 20 bars on barobara.
How traders usually read it
A broken floor is read as the moment buyers stopped defending. Many traders turn cautious, expecting the slide to continue after a fresh low — while bargain hunters watch the same spot hoping for an oversold bounce.
What to watch out for
Fake breakdowns are frequent too — price dips just under the floor and snaps right back. Some read this as big players pushing through the lows to scoop up stop-loss orders. A broken low by itself doesn't mean the fall goes on.
What the data actually shows (BTC 1h)
The common reading is a drop — but what actually happened matters more. This signal has fired 42 times on BTC 1h; across the most recent 42, price reached the small target (+0.25%) first about 57% of the time. Widen the target to ±1% and it becomes about 50%. 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% | 57% | +0.03% |
| ±0.5% | 50% | +0.00% |
| ±0.75% | 45% | -0.07% |
| ±1% | 50% | +0.00% |
| ±1.5% | 50% | +0.00% |
| ±2% | 48% | -0.08% |
Broken down by market regime
⚠️ This table uses a different basis than the symmetric (±) table above — a small +0.25% target with a wide −2.5% 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 (−2.5% stop) | Sample |
|---|---|---|---|
| Bear market | 64% | -0.81% | N=14 |
| Sideways | 80% | -0.38% | N=10 |
| Bull market | 94% | +0.02% | N=18 |
