ATH
All-Time High — the highest price an asset has ever traded at.
An all-time high is the highest price an asset has ever traded at. Traders watch it because old highs tend to act as resistance: holders who bought at the top often sell when price returns to break even.
'Near ATH' is not a bullish or bearish signal by itself. It simply means there is little historical overhead supply. Whether it breaks depends on new demand, not on the chart alone.
