Indicator Overview

The Altcoin Days Since ATH Heatmap is a comparative performance tool that measures the duration of distress or stagnation for one crypto asset relative to another (e.g. ETH/BTC). By calculating the days since a relative all-time high, this tool quantifies the cyclical rotation between assets. It tracks how long a specific pair has been underperforming its previous peak ratio, providing a data-driven look at altseason cycles and capital flow.

The indicator utilises a heatmap palette to illustrate the strength of the current trend. A Deep Red print signifies that the pair is currently at its highest strength ever (a new ratio ATH), while a shift toward Deep Blue signifies that the ratio has been in a sustained decline or sideways chop for a significant period.

How To Use

This indicator is most effective for identifying catch-up trades and rotation points. When a ratio like ETH/BTC is in the Deep Blue zone, it signifies that Ethereum has been underperforming Bitcoin for a prolonged duration (often 500+ days). This typically suggests that it is stretched to its limit, and a reversion to the mean or a new leg of altcoin outperformance may be approaching.

Traders should look for the moment the heatmap begins to warm up, moving from blue to green or yellow. This often signals a momentum shift where the altcoin is beginning to reclaim lost ground. A return to the Red Zone confirms that the altcoin is in a dominant strength phase against its pair, indicating that capital is flowing aggressively into the secondary asset.
