EVA is an analytics terminal for crypto. It shows what is happening with price, with the flow of trades, with the order book and with the money of large players: on the chart, in the panes below it and on the Book & flow, Macro and Money pages.
EVA does not trade, does not connect to your exchange accounts and never tells you to buy or sell. Everything you see is an observation of what happened and what is there now. The decision is always yours.
Numbers come from exchanges and open sources; each block's “?” tip says where it comes from and what it does not show.
