When I trade, am I trading at the delayed price or the actual price?

I know quotes are delayed by 15 or 20 minutes, but lets say I want to trade Company X at 100. I see the price hit 100 so I sell. Would I be selling it for 100, or if it dipped in those 15 mins to 94, Id be selling it at that price?

Does the same apply to options?
