EMA -- Exponential Moving Average
A smoothed trendline that reacts faster to recent price than a simple average.
What it measures: An EMA is a smoothed version of the price that reacts faster to recent moves than a simple average -- like a trendline that leans toward what just happened.
Current price: $64,584
What it signals right now
The 50-day average is below the 200-day average (death cross state) and price is trading below the 50-day -- the medium-term trend is down, though the short-term (20-day) line may not yet agree.
How to read it
- Price above a rising EMA: the trend on that timeframe is up.
- Price below a falling EMA: the trend on that timeframe is down.
- EMA50 above EMA200 ('golden cross' state): medium-term trend is up.
- EMA50 below EMA200 ('death cross' state): medium-term trend is down.
- Shorter EMAs (20) react faster but whipsaw more; longer EMAs (200) react slower but are more reliable.
Typical misreadings
- A single EMA crossover is not a guaranteed trend change -- confirm with price holding the level for more than one day.
- EMAs describe the past and present, not the future -- they lag by construction.
- Comparing EMAs across different periods without matching warm-up leads to distorted early values -- this site always computes at least 4x the period of warm-up data before the first displayed value.
Honest historical context
Golden cross / death cross signals (EMA50 vs EMA200) are widely watched, but they are lagging by design -- by the time the cross confirms, a meaningful part of the move has often already happened. That is a known, honest limitation, not a flaw unique to this site's implementation.
