What is EMA death cross? — chart signal explained

This signal watches how two recency-weighted moving averages (EMAs) — one spanning 20 candles, one spanning 50 — sit relative to each other. Fast line above slow line is generally taken as an up-leaning market; fast below slow, a down-leaning one.

When does it fire? — BaroBara criteria

It fires on the first candle where the 20-candle EMA slips below the 50-candle EMA, after sitting at or above it on the previous candle.

How traders usually read it

With the short-term trend dipping under the long-term one, it's widely read as a warning that the broader direction may be turning down. It's well-known enough that 'death cross' headlines regularly make the financial news.

What to watch out for

It shows up late, only after a sizable decline — so it's not rare for the signal to coincide with a short-term bottom. If the drop ends quickly, a golden cross follows soon after, and that round trip can hurt you on both sides.

What the data actually shows (BTC 4h)

The common reading is a drop — but what actually happened matters more. This signal has fired 178 times on BTC 4h; across the most recent 178, price reached the small target (+0.25%) first about 47% of the time. Widen the target to ±1% and it becomes about 44%. 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%	47%	-0.02%
±0.5%	51%	+0.01%
±0.75%	43%	-0.11%
±1%	44%	-0.12%
±1.5%	46%	-0.12%
±2%	46%	-0.16%

📐 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.

Broken down by market regime

⚠️ This table uses a different basis than the symmetric (±) table above — a small +0.25% target with a wide −3.0% 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 (−3.0% stop)	Sample
Bear market	98%	+0.10%	N=46
Sideways	94%	+0.04%	N=71
Bull market	90%	-0.16%	N=59
