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 (BNB 1h)
The common reading is a drop — but what actually happened matters more. This signal has fired 15 times on BNB 1h; across the most recent 15, price reached the small target (+0.25%) first about 40% of the time. Widen the target to ±1% and it becomes about 33%. 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) |
