# ETH Flow Indicator

This namespace contains endpoints to retrieve entity flow based indicators. We provide certain indicators to avoid any risks, assume upside or downside potentials, and give insights on the value of bitcoin. For more detailed information, please refer to the description of each metric.

## Exchange Supply Ratio

> Exchange Supply Ratio is calculated as exchange reserve divided by total supply. The metric measures how much tokens are reserved in the exchange relative to total supply of the token.<br>
