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)

⚠️ Small sample (5 past occurrences). With this few cases, the numbers below could easily be luck. Treat them as "this happened a few times", not as probabilities.

The common reading is a drop — but what actually happened matters more. This signal has fired 5 times on BTC 1h; across the most recent 5, price reached the small target (+0.25%) first about 40% of the time. Widen the target to ±1% and it becomes about 40%. 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%40%-0.05%
±0.5%40%-0.10%
±0.75%40%-0.15%
±1%40%-0.20%
±1.5%40%-0.30%
±2%40%-0.40%
📐 How to read this. EV assumes a symmetric ±X% target and stop: EV = target × (win rate − loss rate), so any win rate above 50% gives a positive EV. Fees are NOT included — they differ by exchange and order type (maker/taker). In reality fees come off the top, and the smaller the target, the bigger the bite fees take (at ±0.25%, even modest fees eat much of the edge). Timeouts (neither side hit within the horizon) are classified by the closing side, and an asymmetric target/stop changes all of these numbers — setting-dependent references, not absolutes.
