Grayed-out stocks
If a stock shows up as gray instead of red or green, it’s likely that the system has a delay in reporting current market data.
In most cases, waiting a couple seconds will give your app time to refresh and update the respective stock to red or green. If that doesn’t happen, try logging out and logging in again to refresh it.
If a stock delists and is no longer available on major stock exchanges, Robinhood won’t receive active market data for it, and the stock will turn gray.
