Which of IDYA and CPRX is more active right now?

Neither is showing unusual volume on the latest session, so nothing here is being driven by a volume spike.

Is this comparison data live?

Prices and % changes are anchored to the latest completed session and split-adjusted, so a reverse split never shows as a fake move. Float is estimated from SEC filings and refreshed as new filings publish.
