All Time High

The highest price at which an asset has ever been traded.

The All Time High (ATH) typically refers to a peak price sustained for a brief period (e.g., at least 5 minutes) across multiple exchanges, not just a fleeting spike on a single exchange. The price of a cryptocurrency can fluctuate dramatically during short-term spikes on individual exchanges due to liquidity issues or volume surges.

If these fluctuations are isolated, the true price is usually corrected swiftly through trader arbitrage.
