Placement of warning within a trade flow

We need to warn customers who are about to trade a stock that it is currently suspended (https://www.nasdaq.com/glossary/s/suspended-trading). What's the best place and way to notify the customers about it? I was thinking of three possible ways (or a combination of few):

  1. Have a short message above 'Buy/Sell' button with a link to more information about the status of this stock
  2. Have a separate screen that appears when customer clicks 'Buy/Sell' that explains the status of the stock before customer can 'Continue' to Trade screen.
  3. Have a warning message with an explanation in the Trade screen (after customer clicks 'Buy/Sell')

In all scenarios, the customer can still perform a trade but we need to notify them (and possibly provide a checkbox for a consent acknowledging the status) before they continue.

Hopefully that's enough information.

Thanks!
